Nordic semiconductor android ble library github With the Nordic central I found it BluetoothLeService2 has leaked IntentReceiver no. com/NordicSemiconductor/Android-BLE The library simplifies usage of Android Bluetooth Low Energy on Android. If the write request doesn't succeed or fail within given timeout, the withTimeoutOrNull function will cancel the block inside it and return null, so we can handle this case. We tried changing MTU sizes but nothing solve this issue The problem describe by @rickymohk still exist on some devices (with Android-BLE-Library v2. So the library works next way: it stores request and depending of its type - performers different operations in our case You signed in with another tab or window. Note, that newer Android versions will enforce using low power mode in background, even if another one has been The problem is that Android-BLE-Library needs to establish a connection at least 1 time before using the flag autoConnect internally, unfortunately, that's where the troubles begin because I'm looking to use the flag autoConnect precisely because I don't need to connect quickly and I want to save battery life.

However, on Android 13 the bluetooth disconnects with the following logs: 2022-09-15 12:59:30. This just adds a delay, which causes troubles when you write and get notifications from the same characteristic (data is reused for sending and receiving and may be overwritten). [!Note] We're working on a new version of Bluetooth LE library, which eventually will replace this one: Kotlin On Github, the Android BLE Library has a warning in the readme that states that it will be replaced by the new Kotlin-BLE Library. However, whether MTU is 23 (max 20 bytes), or 512 (max 509 bytes of payload), if your actual payload is longer than that you need to Hi, Since Android 12, location permission has been separated from Bluetooth permission. Please let me know if you would need any more specific central or peripheral side logs. You signed out in another tab or window. You switched accounts on another tab or window. It would be great if the BLE library also reflects this change to enable apps to work without location permission when required. It will be addressed in version 2. enqueue() inside. I'm using no. IntentReceiverLeaked: Service BluetoothLeService2 has leaked IntentReceiver Here, instead of using library's . android. android:ble-ktx:2. Hello, I am working on a device with an NRF52. I was wondering if there is an example similar Nordic Kotlin Library For BLE. 1. Reliable Write would cancel all remaining requests and fail, but the base atomic Hello, I'm writing an android application, using no. I What I meant was that it might have been nullified on disconnection (it's not, as uuid is logged) or not refreshed after the second service discovery (so it was obtained on the first connection), but I think even such should work, as all it's used is the handle number, which is the same. 2. ConnectRequest's completion callback is called after the initialization is done (without or with errors). x. 14. To understand things I wrote the central using the Nordic SDK 15. 3. scanner screen; nRF Logger tree for Timber - logs to nRF Logger app using Timber; Android Gradle Plugins - Hi, I need to send/receive more than 20 bytes of data through BLE. iOS part has been implemented in Kotlin Multiplatform and uses native iOS classes like I've begun developing a sample server using the BLE library, to be followed by a sample client using the BLE library. Yes, the atomic queue will complete no matter of the inner requests result. We can easily When I call BleManager. nextRequest where the WriteRequest will be stored to private field private Request request;. 13) Library version: v2. 6. Sign up for GitHub By I think that is an android 13 BLE problem. enqueue() method for initialization requests!. writeCharacteristic where the data has 543 bytes in the array, the call succeeds on Android 12. The problem is, that in the current version all BLE requests are performed from the main thread, while the gatt callbacks use their own thread, Yes, all callbacks are executed in a binder. (Version 2. Library version: 2. A library that makes working with Bluetooth LE on Android a pleasure. In the connectGatt is it now possible to specify the callback thread, but that only means the binder will call the callback on this looper. Move your callback implementation from BleManagerGattCallback to request callbacks. app. Hi, We are facing some issues between our ble devices (ble version 5) and android mobiles using nrfsdk ("Android-BLE-Library") library.

I'm using a Redmi note 7 (Android 10) I got no problems but with a Samsung Galaxy S20 (Android 12) I always have REASON_LINK_LOSS when my BLE device perform a Hi, I use this nice library to connect to a Nordic device and subscribe to notifications from one specific characteristic. Hi, As shown in the title, i've an issue related to random connection timeouts that cause the user of our application to wait too long for a successful connection attempt, that hopefully happens after 10/20 seconds. cancelQueue() in fail handler of each inner request to cancel further requests if you don't wish to continue after a fail. To communicate in both ways, I (the Android app) receive notifications from the characteristic and when I need to send a message, I write to that characteristic and the device replies with the same exact data. I use the BLE library to connect to another Android device with the peripheral role. The GATT service on the peripheral has a We have developed an Android application for a customer (Ibiza) which makes use of nRF's Android-BLE-Library (https://github. Tested on Device: One plus 8T (Model KB2001) OS: Android 13 (KB2001_11_F. I do not think it is a remote device issue since there is no outgoing BLE traffic after the re-connection if I do not do the workaround. Are you missing a call to unregisterReceiver()? android. .
