and get it’s results using meshtastic?
I’ve done this and it was simple, however the old meshtastic forum is gone so all the info I posted about it is gone too.
I used a HC-SR04 range sensor connected to a pair of GPIO on a Heltec V3, the most difficulty was in getting the speed correct and setting the serial.mode SIMPLE on the V3.
I still have the code I wrote
The issue I had was errors in reading so I’d get reading like this:
