My photon crashes if I put it in listening mode. With both method:
I call WiFi.listen();
I try to update with CLI: particle flash --serial test.bin
It blinks SOS reds, the 3-3-3 then 1 slow, then a lot of quick then one slow
But it only crashes if I am not connected the Wifi (turned off the router).
1.5.2 firmware, but noticed at older version too.
Is your device crashing when attempting to enter Listen Mode from a "non-connected" status" only? For example it crashes when LED is flashing green and you try to enter Listen mode through any method? Meaning when connected to WiFi you are able to enter Listen Mode successfully?
How are you calling WiFi.listen() from a non-connected state? Are you running Thread Enabled or Semi-Automatic mode, interrupts?? ?
