The Android app is running on a Motorola Edge phone (Android 10) which implements Bluetooth 5. writeCharacteristic() that take the same parameter Hi Android-Ble-Library developers, I tried to illustrate the communication diagram between a BLE Device and an Android device when I tried to send the data (with my observations). It works as expected on Android 11 and 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, so there is a Hi @philips77, thanks for the response!I'm a coworker of @wcauchois and have been digging into this a bit more.

Contains officially supported repositories. The lib should proceed (repeat the last operation (on older Android versions) or wait until Android does it on its own (on newer)) after the bond is complete. Any nRF5 DK or another device is required in order to test the BLE Blinky service. Indeed, BLE library doesn't call BluetoothGattServer. The phone is the central in my setup and every device notifies data on a characteristic as fast as he Hey All, I'm facing an issue with the BLE connection.

Sometime private final static UUID CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR_UUID = UUID. Android 4. 1). I'm finding that on connections to my peripheral that are not the very first one, but subsequent connections after bonding has already happened, the BleManagerGattCallback. I have tried to follow the code provided by Android-nRF-Toolbox. This library allows to emulate scanning with PendingIntent on pre-Oreo devices by starting a background service that will scan with Hi, Since Android 12, location permission has been separated from Bluetooth permission. By creating BluetoothDevice without scanning, Android will assume public type of address if it didn't scan that device since Bluetooth was turned Android should initiate bonding automatically. Setting the timeout less than 30 seconds definitely helped reduced the frequency of the crashes, thanks for that suggestion! I need to send/receive more than 20 bytes of data through BLE. 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. hi~ Now I pair my mobile phone with the device and connect it with Bluetooth. Follow the snippet below when using the Android-Ble-Library in combination with the Android-Mesh-Library to send and receive data. A library that makes working with 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. If I use built-in Gatt callback, method onCharacteristicChanged get called as expected. There are a few methods that were deprecated in API 33 that I see are still used in this library: BluetoothGatt. So I cant use requestConnectionPriority from the BleManager,or the another way of describing is that I dont know how to use requestConnectionPriority from the BleManager and BluetoothGatt in the same time. Next time I open the app and reconect the BLE device I would like to see if it is already bonded and hide the button. hi,I am using writeCharacteristic to write a value to my BLE device(a light) but when I try to control the light with high frequency, the light cannot catch up with my speed, I mean, not smooth, do u have any idea about this function?

You signed in with another tab or window. 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. 0.
