Wifi.begin crashes device
Posted: Sat Dec 23, 2017 12:35 am
Hello, I am relatively new to the esp32's development but I'm having trouble just getting started, it seems my module does not like it when I try to initialize the onboard wifi. it crashes and fails to give me any diagnostic data what so ever here is what I get from the monitor when using the IDF template application and several others.
py init always fails to calibrate it seems so I thought maybe that was a problem so I turned it off in make menuconfig but that didn't help
I also enabled gdb but that says the following
I powered it up with a lithium-ion battery and it connected but then the battery died and i haven't had the same luck with that battery since, i don't understand how that could make any sense? i have the adafruit esp32 development module and I'm starting to believe mine may just be defective so i went ahead and bought another.
