Well, rc26 appears to be another bust.
I’ve left my mesh running since my last post here last night. It seemed to working properly. After 20 hours without touching anything, I started power cycling the xenons while leaving the argon alone. They consistently reconnected flawlessly and took anywhere from 3-6 seconds to get from receiving power to breathing cyan, which seams to be working properly.
The Argon was basically running code printing sensor data from the xenons to an OLED and also printing its uptime. I made it to 23 hours, 45 minutes, 11 seconds and the Argon appears to have hard crashed. The LED is breathing cyan, the OLED is not updating, and D7 which would indicate incoming data from the xenon is stuck on.
The console ping for both devices shows them as unreachable.
The Xenon LED is flashing green and the D7 LED is blinking to indicate it is still running through the loop sending the sensor data.
Edit: After 30 minutes like that, I pressed the Argon’s reset button. After about 25 seconds the Xenon went back to breathing cyan and the system appears to be working again.
