Just got a rtl515 and trying to use with rwgps. Using rwgps I paired the rtl515, and now on the screen rwgps shows the gray strip on the left. But trying it on a ride, I never heard any tones. I did not set rwgps to keep screen on, so I don't know if there was any visual indication.
I also have it paired to a garmin 245 watch, which gave a buzz everytime a vehicle approached. So I know the rtl515 was working.
Any ideas what could be wrong?
Thanks,
Neal
