thanks for your reply. I wonder is there any demo code that shows how to use this on mDot? I do find some examples using sx1272 library such as this one https://os.mbed.com/users/c_Ake/code/SX1272PingPong/, but after I compile and download to the mdot, nothing happens. I’m wondering how to use this library on mdot.
Thanks,
