Android GATT connected to multiple radinos

[Albert92]

Hello,

I have modified the nRFUART App for Android in order to connect and receive notifications from two different radinos nRF8001. There is no problem to establish the connection with the peripherals but I cannot enable the notifications from the second one. Instead I get the following warning:

D/App﹕ Trying to create a new connection.
D/modifycpuclass﹕ ------------------------>classname = com.example.proves.caminadorBLE.MainActivity
D/BluetoothGatt﹕ onClientRegistered() - status=0 clientIf=2
D/BluetoothDevice﹕ mAddress: C3:EE:DD:D5:E8:CB

D/BluetoothDevice﹕ mAddress: C3:EE:DD:D5:E8:CB

It seems that in onClientConnectionState it keeps the other device instead of the new connection.

I am using one BluetoothGatt and BluetoothGattCallback and also a BluetoothDevice instance for each peripheral. Data is passed to main activity with a local broadcast.

Thanks in advance.

@Albert: Could you post more log when you get the warning ? Did you use separate BluetoothDevice instance for each device ? How do you send broadcast from the service back to main application ? I assume that you need to send extra data to distinguish the 2 peripheral. Could you capture a sniffer trace, we can find what would be wrong with the 2nd peripheral .

Hi Albert,

Have you made sure you used 2 separated instance for BluetoothDevice and BluetoothGatt for 2 devices. Seems that we hit "!address.equals(mDevice.getAddress())" in onClientConnectionState() as in line 173 here.

If possible please share your source code.
