Raspberry Pi & Meshtasticd

Support
1

I just watched Jonathan’s YT video about Meshtasticd on the RPi. I’ve ordered my HAT and now I wait.

I’m preparing my RPi. The video discusses accessing Meshtastic through the webpage, but the video (nor online documentation) discusses setting up a Webserver. Do I need to get Apache running first?

Presumably, you’re talking about this video from Jonathan Bennett. Based off of what’s shown, I would assume that you don’t need to spin up a separate web server – it appears meshtasticd runs its own webserver (the video shows “Port: 443” in the config file, and a “RootPath” entry, both hinting that meshtasticd runs its own webserver).

Hi and thanks to all who have contributed to Meshtastic and a special thanks to the creators of Portduino and meshtasticd.

I am debugging a problem in which the meshtasticd process crashes about every 75 minutes. I see the same behavior on two different Raspberry Pi devices, each running meshtasticd. I’ve set the meshtasticd LogLevel in /etc/meshtasticd/config.yaml to ‘debug’ and I notice a huge stream of empty meshtasticd INFO and DEBUG log messages that seem to lack newline characters and that have nonsensical time stamps such as ??:??:??, 02:44:41, and 15:38:14 on a log entry line from 08:57:41. This one log entry line is 9577 characters long. Perhaps this is the result of a C string that was not properly terminated?

To see this, scroll to the right below. Hopefully the problem can be found and fixed easily.

I haven’t seen any lock-ups. I’m running a RPi 4 64-bit Bookworm with a Waveshare SX1262 HAT. I’m still running 2.3.7 firmware. My node is configured as a Router.

You guys are getting further than me. When I start the meshtasticd service it dies about 64 seconds in with a segmentation fault.

I didn’t find this in any of the instructions relating to meshtasticd docs I saw. I had to uncomment the “gpiochip: 4” line in the config.yaml for that board to work on the Rpi 5.

. ### Set gpio chip to use in /dev/. Defaults to 0.
. ### Notably the Raspberry Pi 5 puts the GPIO header on gpiochip4
. gpiochip: 4
