[Bug]: rak4631 crashes after ~1 day on latest stable fw about firmware HOT 8 CLOSED

How do you have the node configured?
Do you have another node that you can serial monitor log to capture crash data?

from firmware.

How do I do a remote serial monitor capture?

from firmware.

There is no way to do this remotely unfortunately. You'll have to use USB and capture with meshtastic --noproto or a serial terminal like tio or putty

from firmware.

I've been doing battery testing on my RAK node and it has been up and functioning properly for about a week now.

Do you have a lot of nodes in your node list? Are you possibly being flooded with MQTT traffic from the default channel? I've definitely learned my lesson about connecting to the default MQTT channel so maybe that is what's going on here.

from firmware.

I've just now experienced this issue. Upgraded to 2.3.13 and approximately 24 hours later (not sure exactly when because it happened over night) RAK node stops responding and sending telemetry.

I'm a little suspicious that I may have fried my solar charging circuits by connecting a panel that output 6.5 volts. I have a new 19007 board coming and I'll see if the issue exists on the new board in about a week.

Any possibility of posting (or emailing) you battery setup on the RAK?

from firmware.

I have no battery setup. Running it off a usb power supply.

Yeah, I fried the RAK4631 module. Replaced it and now everything seems to be working as expected but the batteries only seems to charge every other day or when the percentage drops below 90. I'm using 3x 150mA 5v rated solar panels, wired in parallel, plugged into the solar charging port on the RAK19007 baseboard. I'm using 2x 2600mAh 18650 batteries wired in parallel with a battery charge/discharge protection board between them and the RAK baseboard.

I plan to eventually install an MPPT charge controller to take over solar charging duty and just wire the RAK in parallel with the batteries. Hopefully this will have a more regular charge cycle.
