Setting DEFAULT_AP_PASSWORD to empty string or "\0" causes boot loop #26

Closed liftoff closed 5 years ago

I tried to set DEFAULT_AP_PASSWORD to "" as instructed in the comment above in wifi_manager.h but this results in a boot loop. Looks like this:

I (0) cpu_start: App cpu up.

Rebooting...

I believe it has something to do with how the wifi_settings_t struct gets created initially. Not sure (I'm terrible with C).

Hello,

You also need to change AP_AUTHMODE in this case. I'll updat the comment to make this clearer
