What BLE block to use when sending data to Micro:Bit

I am trying to send messages to my Micro:Bit. I am New and do not know which BLE Block to use

If you add the Microbit extension from our directory here, you can add a Microbit_Simple_Uart to your project and associate it with the BLE component by setting its BluetoothDevice property in the designer. This extension has a SendMessage block to send text to your micro:bit and a MessageReceived event block to receive messages sent from the micro:bit.


You can also see a complete tutorial using the micro:bit with App Inventor here.
