It sounds like you are trying to pair the Curt Echo part # C51180 to the Bluetooth on your phone which is why the app is not recognizing it. You want to go into your settings on your phone and make sure you disconnect the Bluetooth from the Curt Echo device. Then go to the Curt app and pair the brake controller. If you do not disconnect the Bluetooth from the Echo in your settings it will not allow you to pair on the app. You want to connect through the app not your phone settings.

I had the same issue, I followed the directions to the T and never could completely pair. Blinking blue light, see the device in the app's connect screen, but after 5 to 10 minutes it fails to connect with a red banner. I did everything in the comments and still nothing. So I started to wonder if everything I'm doing is correct but the pin is wrong. So I lifted the lid on the controller and the pin there did not match the one on the card. I have no idea how I got that enter pin prompt to reappear but it did on its own after about 15 minutes of trying to connect the 5th time. I entered the pin from the device and this time it worked. If you have been using the pin on the card compare to the one inside the lid of the controller since the pin there should be matched to that device (one hopes). I guess worse case, is their QA sucks and they placed the wrong pin inside the lid too. In that case, you are out of luck. The thing is, the software does not tell you that the pin is incorrect, it just tries to pair up and then will fail after several minutes.
