Send downlink to multiple devices

@arjanvanb

you’re reinventing the LoRaWAN confirmed uplink, which handles this much better

Or maybe not, emphasis mine:

@cslorabox

the confirmed message scheme is badly thought out - if you’re going to use it, then at least modify the node to never retransmit on failure, instead make the next ordinary message confirmed as well. That’s because if it’s the downlink side of the confirmation that fails, then no matter how many times you re-transmit the uplink, you will never get a confirmation for that re-used frame count.

Best might be to not need any confirmation at all…

@arjanvanb

If this implies that each device is sending a unique ID in its LoRaWAN application payload

Ah, my bad again, you wrote message identifier. Still, it’s text. Don’t send text. See also Multiple sensors with different payload decoding TTN.
