Can't do a WiFi scan, RuntimeError: Wifi Unknown Error 0x0102
Posted: Sun Sep 27, 2020 8:32 pm
I've got an ESP32 devkitc board here and I'm unable to connect it to wifi or even do a wifi scan. The micropython bin I'm using is
esp32-idf3-20200902-v1.13.bin
Here is the code that's generating the runtime error and the output. I've searched far and wide for this error message and can't find any information. My board is being powered by USB and I'm connecting to the serial output on mac using command
'sudo cu -s 115200 --parity=none -l /dev/cu.SLAB_USBtoUART'
MicroPython v1.13 on 2020-09-02; ESP32 module with ESP32
Type "help()" for more information.

Does anyone have any idea what could be causing this? I know the micropython code is open source, but I'm not familiar with the project and I don't know where to find the network module to search for the scan function and see what's going on. I'm not even positive that would be helpful, but that's about all I can think of at this point, I'm really at a loss here.
