Android Bluetooth Low Energy readRemoteRssi

Question

I can\'t figure out how to get the \'onReadRemoteRssi\' callback work.

My code is very simple :

final BluetoothManager bluetoothManager = (BluetoothManag         


        

Answer 1

Put readRemoteRssi() in the callback onConnectionStateChange() of BluetoothGattCallback.

private final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        String intentAction;
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            intentAction = ACTION_GATT_CONNECTED;
            mConnectionState = STATE_CONNECTED;
            boolean rssiStatus = mBluetoothGatt.readRemoteRssi();
            broadcastUpdate(intentAction);
            // Attempts to discover services after successful connection.
            Log.i(TAG, "Attempting to start service discovery:" +
                    mBluetoothGatt.discoverServices());
        }
    }
};

And also put the onReadRemoteRssi in BluetoothGattCallback function　　　

@Override
public void onReadRemoteRssi(BluetoothGatt gatt, int rssi, int status){
    if (status == BluetoothGatt.GATT_SUCCESS) {
        Log.d(TAG, String.format("BluetoothGatt ReadRssi[%d]", rssi));
    }
}
