Switching Gateway and Device Frequency

A post on not sending on AS923, did you read it?

MCCI LMIC payload not received by TTN or node is not sending (AS923Mhz)

Actually at 3m likely too close esp if antennas aligned hence channel bleed and or front end distortion…. Using SF12 means extended Tx hence opportunity for discriminators to do their job over time…… Move to 10m best with absorber in between…wall, window etc. and drop SF’s back, then try again….

And you will see this come up nearly in every thread where people have issues on connecting.
