[admin]

If you are not familiar with modbus, we suggest you download v1.0.7 firmware to your KC868-AK, because every modbus command, last two bytes is CRC code, it's not fixed. i suggest you download this firmware:

  kc868-ak-v1.0.7.zip (Size: 453.15 KB / Downloads: 46)
you only need download firmware to ESP32, then use your computer connect to the board by AP mode, easy to config every button for every actions.
