Duplicate post on gitter, sorry. Just found your forum.
just wondering if loraserver has same behaviour as described here about TTN? https://www.thethingsnetwork.org/forum/t/backend-retry-policy/3599
From my tests it appears so, but maybe im missing something. So thought i would ask before spending too much more time setting up tests.
Ie the server will not send another ack if the node misses the ack and retransmits the uplink.
This is described in one of the example timing diagrams in the spec. Images from the spec are on the ttn thread.
Btw, well done on an awesome project.
