No AP after flashing ESP32 #48

Hello Magnus,

thank you for creating this awesome project. Unfortunately I am not able to see an AP after I flashed my ESP32.

To flash the device I used esptool and my output was:

esptool.py write_flash 0 /Users/morris124/Downloads/flash_esp32_inetbox2mqtt_v264_4M.bin.zip esptool.py v4.5.1 Found 3 serial ports Serial port /dev/cu.usbserial-0001 Connecting.... Detecting chip type... Unsupported detection protocol, switching and trying again... Connecting...... Detecting chip type... ESP32 Chip is ESP32-D0WD-V3 (revision v3.0) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 94:b5:55:fa:1e:b4 Uploading stub...

So I assumed it was succesfully written on my ESP32. The red LED is constantly flashing super fast.

To troubleshoot the issues I already tried a diffrent ESP32 with no success. I hope I'm not missing something obvious.

I would be happy for any advice.

Don't flash the .zip file but the unzipped .bin file. IIRC fast flashing says 'no bootloader', which of course the zip does not provide.
