Wifi AP does not show up after flashing

[emmrichd]

Hello,

I managed to compile the firmware with platformio on windows.
However, uploading within platformio did not succeed. Therefore I first tried NodeMCU-PyFlasher-4.0 with firmware.bin and the espessif flash download tool 3.9.2, uploading partitions.bin to 0x8000 and firmware.bin to 0x10000.
However, I never got an Wifi AP, not with PC power nor with external power.
Please, what do I do wrong?

Regards, Dieter

PS: I managed to flash it via platformio, this works.

Hi Dieter,

Doesn't the serial monitor show anything?
115200,8,n,1

I compiled and flashed it with arduino-ide, becaus platformio didn't work for me. I had to change the name of the main.c to keyble.ino and copie the libraries in the arduino-lib folder, so the gui could find them.

eventualy you have to erase the esp32 with:
esptool.py --port "$port" --chip esp32 erase_flash
