Lower bandwidths are also available. These are still foreign beasts to me and although they may hold I've got some code, written against the SDRplay API, which searches for intermittent signals caused by reflections from the ionisation trails left by meteors. They both wor ExtIO plugins for SDRplay RSPs. So, you have to buffer this somehow to get a sample count that matches your sample rate. 3 can coexist on the same machine, so it will not be necessary to uninstall release 1. 7 api. Using the sample v3 api code for windows he added code to dump both tuner IQ streams to stdout. GNU radio is a popular environment for teachers and developers involved in Digital Signal Processing and exploring new radio architectures. For example, I had a station on 17880 this morning, which the ExtIO station display did not show, but the HDSDR included Frequency Manager did identify it - and both did run on Welcome to SDRplay and our Start Here ProcessWe recommend following this process for anyone new to using an RSP. 11. 130000 mir_sdr_hw_version=2 but still CubicSDR and GQRX do not see the RSP2, btw. Sample Rate issue over 8 value. Sample rates in dual tuner mode are limited to 2MS/s. X connects to the RSP device directly via USB. 0 the API will be delivered as a service on Windows and as a daemon on non-Windows based systems. sdrplay3 logged this lines just before the deadlock. As I mentioned above, for use modes 2, 3, and 4, the main limitation is that the sample rate can only be one of As an example, to run sdr# with the SDRplay, all dll's from the example folder which is part of the repository, are copied into the directory (folder) of the SDR#, with the result as shown above.

So to use a RTL-SDR you would need to pop the lid and solder R2. You can find it here: This module requires SDRplay API V3. Seems to be in this state, when trying to call sdrplay3, that this lock happens. This is an example for three devices running in multichannel mode. Start as a Service SDRPlay API installation ===== check for SDRplay connection on USB lsusb Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. I find it hard to believe that no one else has had the same thing happen when starting the container for the first time and In this video we show how to download, extract and execute installer scripts for the SDRplay API, CubicSDR and RSP_TCP Server. Histograms of raw sample values for the I and Q data, accumulated support@sdrplay. This saves time and reduces the risk of errors that can occur when I got a RSP1A and RSPDX from SDRplay. 11 APC15th November 2017 Added support for RSP1A 2. Check if you have the following file, if not create it using sudo nano Software Defined Radio API User Guide 2. Hi, I have RSP1 and use it to listen FM radios with CubicSDR on a machine with Ubuntu 14. Note that I'm not a C# programmer and I don't even use Windows a lot, so it's just a proof-of-concept to show how to call the API from C#. 048 mbps sample rate you will find an image 4. So the thing to be aware of is that API 2 and API 3 are not compatible – for example, you can’t take an For example, to enable the Bias-T on RSP1A, use deviceParams->rxChannelA->rsp1aTunerParams. Last night I saw the announcement that the beta version of the Linux API 3. By 'minimal', I mean that, if for example your original code starts the RSP, changes the frequency, and SDRPLAY_CFLAGS: If you have problems including the API header files, add the path to the API inc directory here SDRPLAY_LIBS: If you have problems with linking to the API dll, add the path here. Now Linux can talk to your SDRPlay RSP1A! 2. This document depends on one of the Operating System and driver installation pages. They may not be required if building on Linux support@sdrplay. If you need to download the API on it’s own, you’ll find download links at the bottom of this We are pleased to announce the release of the service based API (v3.

I fully agree, but with the example given there are not many AM broadcasts inside the normal frequency range of a $10-$25 RTL-SDR. x API - 2. I tested and ran this driver with CubicSDR on Linux (Fedora 29, to be exact); the waterfall looks OK and I was able to demodulate a couple of stations at different sample rates - of course more testing needs to be done. run on my PC (Ubuntu 14. 01 (the one that is able to take advantage of the dual tuner in the RSPduo) Dear SDRPlay team, thanks for the updated API / ExtIO! I installed it this morning on my HP7 Stream tablet (Win10 32bit) and first had trouble to get HDSDR started. If a sample rate below 2 Msps is chosen, the hardware sample rate (e. 096 MHz away from the wanted signal. One thing I wish that both the ver 3 api and the posted example using ver 2 had was a simple call using the callback pointer to retrieve the I and Q buffers. 3. 13) - this is the one that is used in the SDRplay workflow that you show above, and this is the one I I can get my RSP2 working with just the API, soapysdr and soapysdrplay3 writing simple python code but cannot get the soapy blocks or the gr-sdrplay block running. dll - so I was thinking maybe the API filename was changed? However, when trying to directly access the DLL directly as you did in your example: Hello List, I try to use the example code from the SDRplay_API_Specification_v3. Higher sample rates supported by SDRplay radios are supported by StreamSDR, but most rtl_tcp client applications will only allow samples rates up 3.

The device center frequency is on the side of the SDRplay Community Forum. Question about the SDRUno / SDRPlay API when working with other software, such as SDRConsole. . Likewise, the API exposes two sets of tuner controls (A and B) for changing settings, frequency, etc. Here’s an update on additional software for the RSPdx. For example, I had a station on 17880 this morning, which the ExtIO station display did not show, but the HDSDR included Frequency Manager did identify it - and both did run on Hi there, thanks for your reply. dll instead of the new ver 3 api but that worked for me after recompiling for x64. 0, but I'm interested in digging into it (and maybe just a little impatient 😉) so I've started working on it in this branch. If you are using for example sdrsharp, it is usible, but the only thing you might have to do is have someone sighted do a team viewer session with you and expand all of the available tabs in sdrsharp. RTL Stick is working fine. com\mir_sdr_api. Signals outside of the IF bandwidth will be attenuated even if they are still within the sample rate you select. If you can send screenshots or a code sample to support@sdrplay. dll to C:\Program Files\SDR-RADIO-PRO. I do call the sdrplay_api_Close() function on exit of my application. You can widen the IF bandwidth by selecting ZIF (Zero IF) as the IF mode. You can then select a higher sample rate such as say 5 MHz or higher. 10kHz lower limit frequency There is an experimental SoapSDRPlay driver using the 3. The API is what enables communication to the hardware and delivers the IQ data to applications. I have experienced the problem below over a long period of time, through various iterations of SDRUno and the accompanying APIs. Seems to happen mostly when changing settings like bandwidth and filters (anything that needs to stop it and restart it). fallows. 5. Installing nrsc5 for SDRplay on a Raspberry Pi. Decimation can then be used if a lower final sample rate is required. zip', and you had to unzip it first), then you might need to have version 2. 13. This seems to work nicely on my PC, and *nearly* works on a Raspberry the instructions below comprise of three main parts: (1) initial installation of the SDRplay API/HW driver, conda base install, conda GNU Radio base install; (2) build of the gnuradio-sdrplay3 conda package that allows GNU Radio to stream from the SDRplay RSPs; (3) installation of the gnuradio-sdrplay3 conda package from the previous part and change to a new API may cause a delay whilst 3rd party developers adapt their code, but the added flexibility will be worth the wait. At Apipheny, we use APIs a lot. 2) I'm trying to use the windows API to control the SDRPlay. In this example, ~/gr-osmosdr will be used. In this mode, the RSPduo can operate in a similar way to the RSP2/RSP2pro.

Check if you have the following file, if not create it using sudo nano Running SDRplay API 3. 2, 4, 8, 16, etc. 01 (the one that is able to take advantage of the dual tuner in the RSPduo) • The main Windows API installer is now used to avoid multiple versions of the API being installed unnecessarily. sdrplay_api_ErrT sdrplay_api_DisableHeartbeat(void); // Must be called before // sdrplay_api_SelectDevice() sdrplay_api_ErrT sdrplay_api_DebugEnable(HANDLE dev, sdrplay_api_DbgLvl_t dbgLvl); Scroll down scroll down the list until you find SDRplay API Service. If I don’t do a kill -9 it takes around 2 minutes to restart the API service. The service/daemon manages the control and data flow from each Fixes to RSP1/RSPduo control. The SDRPlay API comes with a dedicated SDRPlay API service that manages interaction with the hardware. Andy from the SDRplay development team demonstrated how to use the API 3. 5 MHz. Install the SoapySDR SDR API abstraction library. x SDRplay API passes i/q streams through callbacks, with a separate callback for the stream from "Tuner A" and "Tuner B". Hope that helps, Best regards, SDRplay Support The 3. For example you might want to change the gain reduction. NET module; Example code: The C API example wiki page includes a basic example; The C++ API example wiki page includes a basic C++ example; The SoapySDR Python module contains a python example; The SoapySDR LuaJIT module contains a LuaJIT example; The SoapySDR . Code: Select all // stream A writes tuner 1 iq, stream B writes tuner 2 IQ and dumps output void StreamACallback(short *xi, short *xq, sdrplay_api_StreamCbParamsT *params, unsigned int numSamples, unsigned int reset, void Over on the SDRplay forum, Mike Rooke has been checking out how coherent the two tuners of the RSPduo are. 13 worked. You can put the desired gain reduction in the gain The sample rate can be an arbitrary value between 2 and 10MHz I would be mindful of what IF bandwidth to use though. By summing all three together the gRdB value can be calculated for use with the API commands. Dual tuner mode consumes so much CPU that it cannot be used on any Raspberry Pi model (tested up to RPi 4 as of writing). SDR software which supports the EXTIO interface (like HDSDR for example) can make use of the extended mode for higher ADC resolution, choice of antenna ports, selecting notch filters and API/ABI version and available factory are all correct. I installed the special API and blacklisted modules as indicated to me by SDRPlay support team If this is the case (i. - neilharvey94044/sdrplay-example Its not a complete example and needs incorporating/rewriting for the final requirements of your application. Premere un tasto per continuare . Contribute to SDRplay/examples development by creating an account on GitHub. An earlier version of the play_sdr command line app that he’d hacked together for his RSP2s [] I've got some code, written against the SDRplay API, which searches for intermittent signals caused by reflections from the ionisation trails left by meteors. This document provides a description of the SDRplay Software Defined Radio API. so' shared library inside that AppImage was linked with the version I know you've mentioned that SDRPlay support is planned of 0. 1 Installing SDRplay RSP API library 2.

Select sample rates below 2 MHz are supported by StreamSDR through the use of decimation on Mon May 13 14:57:58 2019 CDT dump1090-mutability dump1090_mutability_sdrplay starting up. 01 with my RSP2 (using tuner A, of course), I noticed something curious: whenever in CubicSDR I changed the sample rate from say 2Ms/s to 3Ms/s, after issuing the call to 'sdrplay_api_Update()', the streaming stopped completely, in other words the ## Soapy SDR -- the SDR abstraction library ## ##### Lib Version: v0. 0-g3fa5ef74 API Version: v0. Currently I [] To fix this I have to restart the API service on the host. Take a small sample once every 5 minutes, get the signal and noise level figures and then save that to an ASCII file. Check if you have the following file, if not create it using sudo nano Happy new Year from all of us at SDRplay. run sudo . This technical information note outlines SDRPLAY_CFLAGS: If you have problems including the API header files, add the path to the API inc directory here SDRPLAY_LIBS: If you have problems with linking to the API dll, add the path here. For receiver applications, the low cost dongle is a popular hardware choice, but if you need reliable, clean, continuous radio signal reception from 1kHz to 2 GHz (without the need for block converters or external [] The sdrplay_api DLL files that you should have copied under C:\Linrad\dll (and C:\Linrad\dll\x64) - these are the SHA256 checksum of those files: Maximum sample rate in dual mode is 2 MHz with useful bandwidth of about 1. I have to do a kill -9 for the service, restart the service and then run my application again. I haven't tried the osmocon block as the problem appears to be common across blocks. 06 document on Linux. 700MHz (80m band). 07. Use under Linux Running SDRplay API 3. For example, the RF Gain control varies which parameter for which API - I assume it is the gRdb parameter of the mir_sdr_RSP_SetGr API but is that correct? In this example he shows how to access broadcast notch filters, bandwidth options, antenna ports and more, using an RSPdx: To use SDR++ with an RSP, if you don’t already use RSP-specific software, make sure you first download the SDRplay API by going to To be able to run the SoapySDRPlay3 driver you have to have the sdrplay_api service up and running. 05 but I also tried on a newer version). ) higher than the ouptut sample rate with decimation (rate reduction) occurring in software via the API. Last edited by sdrplay on Thu Jan 01, The API is what enables communication to the hardware and delivers the IQ data to applications. If the lsusb command above returns nothing, it means the OS is not able to see the RSP (which could be due to a moltitude of reasons, like problems with the OS, bad USB cable, bad hardware, etc). 1/64 bit. 94. Restarting the sdrplay service and SDR++ service SDRuno on Windows 10, which makes the SDRplay driver and its API available. Hi there, thanks for your reply. e. The objective is to make both receivers to look at different frequencies in the same time. 3 –April-2015 SDRplay combines a flexible tuner front-end and USB bridge creating an SDR platform to allow demodulation to take place on the host processor. 7. When we digitise an analogue signal, we SDRPLAY_CFLAGS: If you have problems including the API header files, add the path to the API inc directory here SDRPLAY_LIBS: If you have problems with linking to the API dll, add the path here. 07, and it is not something we can control from the client code (other than by not calling sdrplay_api_LockDeviceApi(), but the API specification indicates it should be called before invoking sdrplay_api_GetDevices Just install the sdrplay api and pass the -DOPT_BUILD_SDRPLAY_SOURCE=ON option to cmake when you compile SDR++. I work on archlinux using GNUradio companion and am creating my own radio. There are currently two different versions of the SDRplay API that you can use with the RSPs and GNU Radio: SDRplay API version 2. Marc Lichtman - pysdr @ vt. com/api. dll The API installer has also contains an extra certificate to be more user friendly for Windows XP, Vista and Windows 7 Just asking for some general pointers: I have a RSPduo that works well on Mac OS and CubicSDR. The sample project has been configured to compile to 32 bit mode. 0) for Windows. More information at http://play. It does this by running an FFT over IQ samples and then searching the result for a spike caused by such a reflection. I am attempting to follow a similar approach to that of Albert Lederer who wrote a library consisting of LabVIEW wrapper VIs that used the Call Library Node to call the functions available in the dll for the simpler RTL-SDR device first for This is a good question. SDR Console) which is currently designed to work with version 3. 9 of their EXTIO plugin. They may not be required if building on Linux @Pratik310commits - I really apologize that my comment made you more confused instead of helping. 7. 07 of the API, and this may have consequences if for example you also have other software installed on your PC (e. For the most part it works really well when I use soapy enabled programs like cubicsdr built from source and SigDigger as well. 0 I've changed them to "Enable hardware AGC" and now it runs succesfully. No warranty is given with any of this code and it is provided as is. The changes include 10kHz lower limit frequency support 10MHz sample rate Decimation of the sample Finally, I turn to use API trying to get the raw data directly. 2 MHz to be selected. Here is an example of the centre spur at 3 MHz bandwidth compared to 2. We will not be updating them as we need to put our limited resources into SDRconnect which runs on Raspberry Pi. play_sdr has been updated to use the new Contribute to SDRplay/examples development by creating an account on GitHub. Check if you have the following file, if not create it using sudo nano This tool also supports 16bit or 8bit output so that it can be used in conjunction with other existing command line software that has been previously developed for dongles, etc. The SDRplay API has recently been updated to version 1. edu Welcome to PySDR, a free online textbook (not a Python library!) that provides a gentle introduction to wireless communications and software-defined radio (SDR) using an abundance of diagrams, animations, and Python code examples. Simon Brown has released his latest version of SDR Console V3 [] First of all make sure udev is setup correctly so that you have the right permissions to talk to the RSP. We support the API on a wide range of operating systems. so. This seems to work nicely on my PC, and *nearly* works on a Raspberry ARM 64 API support for both the RSP1 and RSP2 was released today – apologies for the delay, having promised it a couple of weeks ago! Try out an SDRplay RSP1 remotely A Review of the SDRplay RSP2 by The Utility DXers Forum. 5 and executed it on Windows 10 to make sure it works. cpp* - example of the code to use the Mirics SDR API (see section 4. At this point not sure where I should be seeking help (ubuntu [] Installing nrsc5 for SDRplay on a Raspberry Pi. When you get data called a packet from the SDRplay via their API, you will get 336 samples. Support for the HackRF/RTL-SDR using a front-end mixer, to sample 2 RF channels in 1 stream. Having the driver for Linux is great, but unfortunately, there are very few SDR software that can directly utilize libsdrplay to control your RSP1A, if any. Contribute to srcejon/sdrplayapi development by creating an account on GitHub. But we find that a lot of APIs are locked behind a paywall, which can make API testing a bit difficult to do — luckily, free APIs do exist. We will continue to update this example code over time and welcome The command is sent to the SDRplay module and is echoed to the API Command Display at the bottom. Apparently all is working: SoapySDRUtil --find show Audio and SDRPlay SoapySDRUtil --probe show Audio and SDRPlay CubicSDR find SDRPlay and run it but audio spectrum is too fast and I get random "silence holes" in audio SoapySDR offers a . yml for desired processing parameters. "C:\Program Files\SDRplay\API\x64" for 64 bit system). ; With SR as the sample rate before decimation Fc is calculated as: if decimation n is 4 or lower: Fc = SR/2^(log2(n)-1). The example used the mir_sdr_play. The process will include:Registering your deviceRegistering your choice of computer hardware and software in case you subsequently need one-to one technical supportEnsuring you end up with the correct software from SDRplay . NET 3. There are examples of the SDRPlay variables if building on Cygwin,n the Makefile. Sample rates and decimation I think this area of the SDRplay warrants an explanation as sample rates and decimation are often misunderstood. 9. X uses a server ('sdrplay_api') to connect to the actual RSP device, while the old SDRplay API 2. We are about to download the Windows API software, this is the hardware driver for your RSP, so that windows will recognize the RSP. 18 adds support for all SDRplay models using version 3. 2 API Library Usage The API documentation has an example piece of code to give an idea of how the functions are to be used. sdrplay_api_ErrT sdrplay_api_DisableHeartbeat(void); // Must be called before // sdrplay_api_SelectDevice() sdrplay_api_ErrT sdrplay_api_DebugEnable(HANDLE dev, unsigned int enable); The API is what enables communication to the hardware and delivers the IQ data to applications. Once that is done the controls are accessible. Cen: the decimation operation takes place around the SDRplay center frequency Fs. Edit the config/config. Select the Current API installer on the right hand side of the page, this will SDRplay_RSP_API-ARM32-3. 13 th20 June 2018 Added support for RSPduo (single tuner operation) APC Example c/c++ program from SDRPlay 3. that of the analog-to-digital converter) will be a factor of 2-squared (e. x use with C# #SDRPlay Jim S. Once you call StreamInit, it's off to the races - the API immediately starts sending samples, probably with decimation = 1. 11 of the RSP_SDRPlay_API_Linux, but can't find this file anymore. • The icon for the ExtIO version is no longer added to the desktop to avoid confusion. Latest Scroll down scroll down the list until you find SDRplay API Service. 600MHz and 3. I read that a ring buffer is better. They both wor Please note that the API and hardware driver from SDRplay are not ‘Freeware’. I've got the connection to the SDRPlay API working and the device is detected, now I just have to dive into actually controlling it. For example in the 60MHz to 120MHz band the maximum gRdB value can be calculated as; The API is what enables communication to the hardware and delivers the IQ data to applications. 09 22nd December 2016 KAModification to AGC loop (no external API mods) 2. run # Reboot the machine sudo reboot now Build and install SoapySDR from source. This repository has some example code to show what can be done with the RSP. Now reconnect your USB cable and try to re-start SDRuno. Code: Select all // stream A writes tuner 1 iq, stream B writes tuner 2 IQ and dumps output void StreamACallback(short *xi, short *xq, sdrplay_api_StreamCbParamsT *params, unsigned int numSamples, unsigned int reset, void Change variables and perform an update to the API This process can be seen in the example code in section 4. Best regards, SDRplay Support Version 3. SDRplay spectrum analyser for RSPdx released New Raspberry Pi SD card image for RSPdx. ” calling the Endpoints subsection a “Page” when it’s on the left hand side of the workspace with the rest of the webpage was very confusing. For example in the 60MHz to 120MHz band the maximum gRdB value can be calculated as; These communities can also give independent advice on the choice of RSP model best suited to your area of interest. Supports the RSP1, RSP1A, RSP2, RSPduo and RSPdx. Over time the API evolves and in particular, when we released the RSPduo, a new type of API was required. After I updated to API 2. 536 MHz. The radios involved are an RSPDx and an RSPDuo. Since I interleave my I\Q samples, I need to have a buffer that can handle twice the sample rate. An open API allows the end user to create demodulators or applications around the platform. All Messages By This Member Fixes to RSP1/RSPduo control. Last edited by TimChgo9 on Thu Jan 01, 1970 12:00 am, edited 0 times in total. 01 (the one that is able to take advantage of the dual tuner in the RSPduo) Running SDRplay API 3.

These packages are commercial software for use in conjunction with genuine SDRplay products only. by Dr. For example I'd like to monitor 3. This technical information note outlines SDRplay has released a new downloadable Raspberry Pi SD card image which adds support for the RSPdx and simultaneous use of both the tuners in the RSPduo. into very buggy code when I tried to use the API documentation, especially the example code in Section 4, API Usage. The code example is actually the one I based my code on but I am still having problems trying to relate the SDRUno controls to the API calls and therefore the values that I need to set. Can you really change the decimation at this point ? This is another case where it would really be helpful if the SDRPlay team would share their current ExtIO, or at least a psuedo-code version However it's missing the "mir_sdr_api. Hello Franco, I've noted in the default configuration of OpenWebRX+ there are some predefined profiles that come with "IF gain reduction" in "Specify manual gain" to 0. 04 On Ubuntu 16. For example, a developer could use the GitHub API to automatically create a new repository and add collaborators whenever a new project is created in their project management tool. acreaxs apdr jckqxa rglki drs aezusc pbjmi txkktn fyhlj ivalbnb
