Sure, I’m aware that TTN will validate the counters. I’m not using TTN on those tests. I’m running my own loraserver, then I can ignore the counters if I have to.
Anyway, I read the thread you mention about OTAA best practice, and I’m still confused about the ADRACKReq command. On my analysis here I believe that forcing the NS to send a ADRACKReq command would solve my current situation and probably can be the final solution or part of it. Using the MKRWAN lib I can easily keep track of the counters, but as far as I know I can’t mask the channels by myself (there’s no AT command to do so), that’s why I need the NS to send the ADRACKReq MAC command to the device, defining the channels to be used.
Thanks again.
