I had the same issue. : ( Device: Android 12 react-native-ble-manager version: 10.1.2 react-native version: 0.71.2 BleManagerDidUpdateValueForCharacteristic did not trigger when startNotification

On IOS device BleManagerDidUpdateValueForCharacteristic can listen the data, but on Android device, I had this problem for the above phone Galaxy s21

@Srikanth-Enuguru, you still had issues with your Android device? Try another android version or update [v.10.1.3](https://github.com/innoveit/react-native-ble-manager/releases/tag/v.10.1.3) ? Device: Android 12 react-native-ble-manager version: 10.1.2 react-native version: 0.71.2

> BleManager.requestMTU(chosenPeripheral, 512) > then > BleManager.startNotification My case was fixed by ``` BleManager.requestMTU(chosenPeripheral, 512) then BleManager.startNotification ```
