Hello everyone

The example code "UltrasonicRF_test" does not work for me, did someone else experience any problems there? The sensor is working if I use it with 4 wires (Echo and Trig separately).

Thanks for your help :slight_smile:

There is also one unclear formulation in this section: "Make sure that the cable is modified correctly like shown here (one of the cable’s in the cable assembly needs to be moved from the 2nd to the 4th position)".
If you must move something than it can just be between 2nd and 3rd position.
Please just tell us which signal pin must be connected. Gnd and Vcc should be clear though.

Hello,

Provide us a picture of the circuit built where we can see the wiring on the board and a screenshot of the error you're getting.
