Wifi -- why so hard?

[segdy]

Phew, surprising I am getting stuck here at connecting to Wifi.... Usually there's an AP for initial configuration or at least configuration at compile time.

I am just re-using an ESP32-CAM module to play around so I don't have a switch.

Flashing the compiled firmware works well but how the heck do I get access to the serial console? I tried connecting to the COM port via putty, tried 9600, 115200, no flow control, 8n1 but I either get nothing or just a few characters of garbage.

Is there any straight forward way to get connected to the Wifi so I can just play around with the HAP part a bit?

@segdy it does work with 115200 on the serial port. After connecting, reset the device so that it runs through a clear boot. I used CoolTerm on MAC. If you then press "A" it does start a local hotspot

[segdy]

Thank you. Still no luck :-(

Pressing reset button does nothing. Unfortunately I can't open the serial console from boot on because once I unplug USB, the serial port is gone. So after plugging in I have to wait a fraction of time to open the serial port. When I success I get the screenshot above.

Again, it flashed successfully so it can't be completely off.

that looks like either wrong baud rate or the serial bridge is a bit funky. The correct baud rate is 115200 and is defined here

Try the new version, now the access point autostarts at boot.

Absolutely amazing!! So much just happened :-) :-)

I tried to build the newest version but I am getting tons of errors now. I updated platform IO and I also cleaned everything and push'ed the latest version:

Meanwhile I downloaded your repcompiled binary and flashed if via esptool.py. I could eventually connect my Wifi, add it to Home app and now the key is already showing up in my wallet :-) :-) So awesome. I'm stoked and looking forward for the NFC reader to arrive, but this looks already so promising. Thanks for the great work.
