Same experience again with a stand-alone Argon running 0.9.0. Was about to update it.
Again a hardware reset does not get it online. Surprisingly the EN pin did not get it online either …
In both cases the Argon restarts and blinks green for a few seconds then signalling that it is online breathing Cyan. But the console show it as offline - even after reloading. Can’t ping or signal. Also it is not performing it’s function (AC control).
After a short while the Argon blink cyan for a few seconds and then breathes Cyan but it still not online.
If I cycle power removing it, the Argon jumps online happily again for true.
Lesson learned looking for a reliable watchdog concept for a new always online product based on Argon/Boron:
- LED and particle.connected() can not be trusted even right after a restart.
- Neither the RST pin or the EN pin alone with a HW watchdog is sufficient recovery
