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

I need UART Service and HRS service both data at a same time. to get UART profile data, i have accessed service and characteristics in enableTXNotification() function in UARTService.java I have same tried with HRS profile in same function , but it is not working.

sample code below:

public void enableTXNotification()
    {
        try {
        BluetoothGattService RxService = mBluetoothGatt.getService(RX_SERVICE_UUID);
        if (RxService == null) {
            showMessage("Rx service not found!");
            broadcastUpdate(DEVICE_DOES_NOT_SUPPORT_UART);
            return;
        }
        BluetoothGattCharacteristic TxChar = RxService.getCharacteristic(TX_CHAR_UUID);
        if (TxChar == null) {
            showMessage("Tx charateristic not found!");
            Log.d("no tx char ","Tx charateristic not found!");
            broadcastUpdate(DEVICE_DOES_NOT_SUPPORT_UART);
            return;
        }
            mBluetoothGatt.setCharacteristicNotification(TxChar,true);
            BluetoothGattDescriptor descriptor = TxChar.getDescriptor(CCCD);
            descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE);
            mBluetoothGatt.writeDescriptor(descriptor);

        BluetoothGattService RxServiceHRS = mBluetoothGatt.getService(RX_TSSERVICE_UUID);
        if (RxServiceHRS == null) {
            showMessage("Rx service not found!");
            broadcastUpdate(DEVICE_DOES_NOT_SUPPORT_UART);
            return;
        }
        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;
        }
