I've been struggling to get my new Bontrager Duotrap on my new Trek to work. It won't sync with any of my devices … or I should say, I can't figure out how to do it. When I look at the documentation on paper or on line, it tells me a lot about how to install the thing, but not how to link it with my phone, watch, whatever.

I know someone out there has dealt with this. If you can help, please!

The diagnostic information:

• I have a Samsung Note 10+ and a Samsung Frontier 3 Watch. I also use Strava, which does not seem to give me diddly from the computer.
• When I spin the wheel, the sensor light goes on
• Most of the time when I go to Bluetooth on my phone (when the light is on) the phone does not pick up the Duotrap
• One (count'em, 1) time the Bluetooth listed it. But when I tried to synch it gave me an error message. I was so frustrated I didn't record the message, which I should'a.

Is this thing just crap?
