For some reason on some of the XRP’s the sensor has stopped working on one device, but if we attach the sensor to another XRP robot it works. Is there a way to program the sensor to work from another connection. IE the “Line” sensor work out of the “Extra” connector? ---

Hi there, Which sensor are you referring to? And in what way did it stop working? Did you get any error messages, or is the data just bad? ---

I have had problems with the range detector and line follower on different units. When I run the test to check out XRP they line sensor values do not change, same with the range values. But when I use the same sensor on another robot they do work. ---

Ok, sounds like the sensors themselves are fine then. When you swap to the other robot, are you using the same cables? My hunch is that you have a bad cable, or a bad connector. If the cables all seem fine, then it’s possible your control board is damaged. ---

Also, the line sensor will only work on the “Line” connector, because that’s the only connector with 2x ADC-capable GPIO pins. And the GPIO pins on the “Extra” connector have other default uses, so best to leave that connector alone unless you know what you’re doing. ---

We have occasionally seen bent pins in the connectors. With the sensor unplugged you should be able to look down at the connector and see all 4 pins. Young eyes or a magnifier can help see if any of those are bent. ---

Thanks, I know what you mean, I’ll check that out.
