Hi @scle
Now I can understand it better, thanks! However, after reading LoRaWan spec, I have a nother question more related to the real implementation in the TTU, since in order to check whether or not my mote has got something from the gateway I have to check if mac_rx has been received right? So, if I am transmitting mode and this string shows up, I will have to read the data as something send me back by the server , is that correct?
