I don’t have the watch but does the manual that comes with the watch show WiiWatch2 as the correct app? Or you could use WatchDroid unless you have an iphone.
WiiWatch2 also shows WiiWear in some screens, so i think it’s the right application to use. However, i have not succeded in pairing with the watch. In fact to be precise, the pairing succeeds, but the wiiwatch application doesn’t see it. Watch and phone are still not seeing eachother, even if they are well paired.
Maybe a problem with those early FW versions.
