Hi all,
I have a LYWSD03MMC laying around on which I seemded to brick the firmware via flashing over OTA. Now to revive the device and switch to Zigbee while Im at it, I would want to use an Raspi 2 as UART programmer, so I dont have to buy one just for that project.
The wiring is clear after I read through the documentation here GitHub - pvvx/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometers and Telink Flasher and I checked the UART PIN on the Raspi for the output of 3.3V.
Where Im currently struggling a bit, what software do I use in this case to flash the new firmware on the MCU? As the web flasher is designed for USB, I guess that should not work? Installed Raspbian without a GUI, otherwise I would try going that way for now.
