Cli is telling me the spark recieves the flash upload. The core blinks magenta a few times, then the multicolor led goes completly blank no power for a second (core still getting power). The inexplicitly goes back to the old sketch right to cyan, no green searching for wifi.
Try flashing again and see what happens. I had some encounters with this when running on a program with super tight loops and OTA not being triggered correctly sometimes.
Tried again same deal, though I had already tried quite a few times before that.
The only major difference I see from my last good upload was the addition of a 13 char array. I might have ran out of ram? or maybe that is a red herron. I can reduce the size a bit… and I’ll test it on the web ide
When I started testing the new loop I created, seems to stop on an output that would normal shut in a reasonable loop time and then the multi led starts flashing red until it resets a second later.
Try to isolate the trouble statement with serial prints. The flashing red is the core in panic. This is could be a number of things so isolating the statement will help. Could be memory, could be a pointer, isolate the statement. Keep tinker and a blank sketch handy to overwrite. Good luck!!!
