Could two boards be connected to iOS app simultaneously?
Could two boards be connected to one iphone app simultaneously?
More than one board can be Paired to a phone but only one board can be connected. Just like your other devices and speakers and headphones.
If you ride with a friend and have his/her board Paired on your phone I would go to your board settings and turn off the auto connection so that your phone won't randomly pick-up info from a board nearby, especially if you lose connection to your own board
