Hello, I have set up the v4 controller board and 3 v4.5 modules programmed with AVRdude serial programming (UPDI). However, when I power the controller, it will not register any of the modules, whether or not there is a battery connected to the module. I have verified the controller by connecting TX to RX and seeing the ignored requests coming in. For now I am powering the controller by the ESP32 usb cable.
Hello, I had the same problem, controller ESP8266 v4 and v4.5 modules. In the platformio.in for controller esp8266 i changed -DCOMMS_BAUD_RATE=2400 to -DCOMMS_BAUD_RATE=4800 and all working.
