Version parameter error in AU_915_TTN

[aalbinati]

Thanks @facchinm ! Arduino MKR 1310 now joins correctly and at the first try in the 1.3.1 branch!
But I am afraid there's an error showing up when sending packets to the network server.

In my chirpstack server this shows up:

Jan 30 18:24:43 ip-172-31-14-1 chirpstack-network-server[828]: time="2021-01-30T18:24:43Z" level=error msg="uplink: processing uplink frame error" ctx_id=85c97751-bb45-4364-bc74-4554358d5261 error="create uplink frame-log error: marshal phypayload error: lorawan: max value of Minor is 7"

This error is referenced here: Chirpstack Code

It seems it has something related to LoRaWAN version specification inside the AU_915_TTN configuration because AU_915 does not have this error.

Tell me if I can be of any help solving this issue!

Hi @facchinm !
Maybe I didn't explain correctly what's happening. The MKRWAN 1310 now connects reliably in AU915_TTN because its using only the sub band 2. The same one the gateway is listening to. The problem is that the payload is not correctly configured when trying to send the uplink packets. On band AU915 it this works fine so there must be some minor error causing this problem. Tell me if I can be of any help solving this issue.
