I have connected to a bluetooth device. I am able to read charectristic using mGatt.readCharacteristic(getMiliService().getCharacteristic(uuid));

But I am not able to register indicate for a characteristic.

What I tried boolean flag1 = m_Gatt.setCharacteristicNotification(bluetoothgattcharacteristic, flag); BluetoothGattDescriptor descriptor= bluetoothgattcharacteristic.getDescriptor(Helper.UUID_DESCRIPTOR_CLIENT_CHARACTERISTIC_CONFIGURATION); descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE); mGatt.writeDescriptor(descriptor); descriptor.setValue(BluetoothGattDescriptor.ENABLE_INDICATION_VALUE); mGatt.writeDescriptor(descriptor);

and waiting for onCharacteristicChanged(BluetoothGatt bluetoothgatt, final BluetoothGattCharacteristic characteristic)

method getting called. which never happend.

I am not sure what I am missing here.

Can anyone give a working example for indicate?
