It's definitely the app. Just checked the web. The EW-WU111 is a Bluetooth LE, which will not appear in the normal Bluetooth settings section. Apparently LE only appears through the various appropriate apps for connection. Neither E-Tube ride or Project on iOS will sense it. Again, may be the app, may be the beta iOS. But I checked BT on my Windows PC and sure enough, EW-WU111 appears there via Bluetooth. I'll file a report in the beta testers forum, and cross my fingers that it will be resolved in the final iOS release.
