My device needs to be connected to WiFi though right? And my rak 4631 doesn't have WiFi. My heltec-v3 does though. I can get that setup tomorrow.

i've never used MQTT before. i enabled wifi on my heltec. i made sure this channel was uplink and downlink enabled. i've senet messages. i guess lemme know if you get them?

oh i also turned on MQTT, using the default settings.

i still have 0 idea if im doing any of this right lol. believe i have MQTT enabled and my device is connected to WiFi.
