Maxbotix LV-EZ04 to Pixhawk over Serial

Hi guys,

Has anyone managed to connect a sonar to a pixhawk using anything other than analog or i2c? I’m trying to interface the sonar with the pixhawk’s serial 4 port usinga TTL inverter but I’m not sure which protocol to setup the serial port to in MAVlink.

Any help would be appreciated :slight_smile:
