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`

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

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
