I'm trying to get the HC-SR04 sonar to work on Naze 32 Rev 6, running the latest v2.0.2 software, but it doesn't seem to be working.
I'm connecting the echo and trigger to the pads on the back of the Naze (supposedly has built in resistors). The Naze is getting 3.7V from a battery; the voltage is supposedly outside of the voltage range of the sonar, so to eliminate a source of problem, a steady 5v is supplied from my arduino.
In clean flight, the sonar mode is turned on. The sonar status icon on top does not light up; no signals are coming through in the sensor's tab.
I can't figure out why it's not working, so I hope someone on here has the answer.
Thanks in advance lads!
