Hi, I'm currently running into some weird issues with Wifi sometimes not connecting properly. I've cut down the issue to essentially the scan example from the IDF repository (Code Attached). The issue occurs on both Devkits I have here, as well as a bare WROOM32 module. On a good boot I'll get: I (2...

In my application I'm measuring the amount of times a line has been pulled low per second by a hall senso...
