Hi there,
I’m really new to LoRa, so i apologize if making a dumb question. I’m using a Class A end-node, with OTAA, which timeouts waiting for an acknowledgement message to the sent ConfirmedDataUp message. When looking to the lorawan’s frames logs it is kind obvious that the server is not sending the ack message, my question is why?
