uploading using esptool

[netzbasteln]

I was able to upload the binary using esptool.py instead of the windows-only app by espressif.

esptool.py --port /dev/cu.wchusbserial210 --baud 921600 write_flash --flash_size 4MB --flash_mode dio 0 dtuGateway_release_1.6.0009.bin

I used the esptool to flash the ESP32 on my mac. Seemed to work.

esptool.py --port /dev/cu.SLAB_USBtoUART --baud 921600 write_flash --flash_size 4MB --flash_mode dio 0 dtu.bin
esptool.py v4.8.1

I assumed, I'd find a new Wi-Fi network from the ESP's access point afterwards, but nothing.
Any idea?

can you show your serial log after rebooting ... there should be shown that the AP was started or if there are any general errors.

Usually your assumption is right... after first flashing dtuGateway is starting in "factory mode" and starting an own AP for first setup.
