I'd still have to be close enough to you to actually use this channel, right?

I do not believe so. I set this up so that it works over the internet as well.

First time setting something like this, so not entirely sure.

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.

i scanned the QR and tried to send a few messages in the channel, no idea if they're going anywhere. i have a max retransmission reached error.
