Incorrect Soil Sensor value

Hello there My Soil Sensor work abnormal when I use the Farmbot Arduino v4.0.0 **UART command “F42 P5 M1” --> always return “R41 V987 Q0” After I traced it and found below code in farmbot_arduino_controller.cpp pinMode(UTM_D, INPUT_PULLUP); I remove it and the Soil Sensor return value is correctly. Is it a bug? Thanks! FBTUG(Taiwan)
