because RS485 and 4G module use same serial port. if you not need to use RS485, you need remove IC:U26 (74LVC1G125) . Then you can use 4G module.
we have update KCS A8M firmware for V2.2.4 to solve the 4G module problem. just download it directly to use.
Thank you very much for your quick response and support. I purchase several SHT20 RS485 Modbus modules to get samples from several places. Anyway, I will use an alternative.
