Is there any known protocol to control CC and CV? I bought a D3806 which has the same control board as the b3603 and hoped to be able to control it like described here: https://blog.benjames.io/2018/06/29/secret-uart-on-chinese-dcdc-converters/

but everytime I send something over the UART connection nothing comes back

The serial port appears to be used to program the microcontroller.

P.S. you might want to take a look at my active project https://github.com/rin67630/Drok-Juntek-on-steroids, where I completely replaced the control unit with an ESP32 jettisoning the device in a complete new WiFi enabled realm...
