+1 to Skydog's description. Another pebble2 + android = no connection.
(In case the details differ... I can Bluetooth pair the two, but that's it. The app never really seems to search for a pebble2: from the "manage pebble" screen, click "find a new pebble", click "Pebble 2", and the app goes back to the "manage pebble" screen with "find a new pebble" at the bottom. if I click "find a new pebble" and any other model besides "Pebble 2", the app goes back to the "manage pebble" screen but has "stop searching" at the bottom and the progress chaser thing in the upper right
I also tried the "pebble old version" app since I still have one of those, but interestingly it doesn't find the pebble 2 but does show the pebble time I have.)
