We setup a RUI3 lorawan RAK3172 node and use api.lorawan.send() successfully. This api call returns true if the node is setup with a confirmed message and the message is not confirmed (lora router turned off). Is this api call supposed to return false in this case as the uplink message was not successfull?
Alternately, we could check the status in the TX callback. Is there any documentation for the status value that is passed into the TX callback? It seems to return a 4 for confirmed uplink failure.
