GY_US42 UART protocol

ArduCopter
1

hello,

I’m trying to use GY_US42 (Ultrasonic Distance Measure Moduler) on the serial4 port of Pixhawk but no distance sensor showing at the sensors menu . (I tried the sensor on I2C its working correctly)
here is the setting that I made for serial4:
SERIAL4_BAUD = i tried 9 and 115
SERIAL4_PROTOCOL = 9
RNGFND1_ADDR = 112
RNGFND1_MIN = 20
RNGFND1_MAX = 700
RNGFND1_TYPE = i tried 13 and 31

Any response would be appreciated
Regards

Thanks for your reply.

Cool. Explains why you can’t run it; it’s support is only on master.
