Nordik UART app with Multiple service reception

[Shrikant]

I need to receive both UART Service data and HRS service data on the app.

Currently I have seen on Nordik Connect app , both the services can be found and can connect and receive data.

I need to do same with my app using nordik UART App code.

I have changed UART profile to HRS profile and code was working, i was receiving Nordik HRS service data.

But i want both services should be used and receives data. so i have prepare separate UARTService_HRS for hrs profile in the same code.also added needed changed.but it gives error null pointer exception on BLEGattService.

Please help

If the service object is returned, have you check which characteristics are belong to that service ? You can call RxServiceHRS.getCharacteristics() to get the list.

One thing I noticed from your code, you call :

  BluetoothGattCharacteristic TxCharHRS = RxService.getCharacteristic(RX_TSCHAR_UUID);
        if (TxCharHRS == null) {
            showMessage("Tx charateristic not found!");
            Log.d("no tx char ","Tx charateristic not found!");
            broadcastUpdate(DEVICE_DOES_NOT_SUPPORT_UART);
            return;
        }

Shouldn't it be:

  BluetoothGattCharacteristic TxCharHRS = RxServiceHRS.getCharacteristic(RX_TSCHAR_UUID);
        if (TxCharHRS == null) {
            showMessage("Tx charateristic not found!");
            Log.d("no tx char ","Tx charateristic not found!");
            broadcastUpdate(DEVICE_DOES_NOT_SUPPORT_UART);
            return;
        }

RxServiceHRS instead of RxService ?
