Make sure you have miniterm installed 'sudo apt install miniterm'

Connect the device directly vis usb or a serial to usb converter

Enter `dmesg` too see which ttyUSB[X] device it is, where [X] is a number (probably 0)

Crank 'miniterm /dev/ttyUSB[X] 115200 -e' into the terminal.

Hack 'Status 11' into the terminal and see the wifi params.

If you need to reprogramn them prepare the following line in kate (or any other text editor):

Backlog SSID1 yourwifi1; Password1 yourpassword1; SSID2 yourwifi2; Password2 yourpassword2; MqttHost 192.168.2.5

Then copy and paste it into the miniterm and hit enter.

It should restart and connect to your wifi finally…

Cli only / (no vscode needed)

Look here but install python3-pip instead of python-pip on ubuntu >=20 https://tasmota.github.io/docs/PlatformIO-CLI/#download-the-tasmota-source-code a backup is here installplatformio-copy

Put this at the end of tasmota/user_config_override.h. Fill in passwords and MQTT Server.

For typcial sonoff use this to compile and upload:

platformio run -e tasmota --target upload --upload-port /dev/ttyUSB0

For esp32 and bluetooth use this:

platformio run -e tasmota32-bluetooth --target upload --upload-port /dev/ttyUSB0

Or esptool

esptool.py -p /dev/ttyUSB0 --chip esp32 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dout --flash_size detect 0x0 tasmota32.bluetooth.bin

If compiler errors about missing dependcies show up delete your .platformio folder, which might contain files from previous platforms
