Hello, I'm asking for help because I have a problem.
My application consists for the moment in 2 pages, a first one of welcome where we connect the app to an Arduino board in bluetooth via a bluetooth module (and in the future directly to the board), and then a second one with buttons supposed to send a letter and in return the arduino code launches its instructions at the reception of the said letter.
You can't go to page 2 until the bluetooth device is connected, and yet when I press my button on page 2, I get a 515 "Not Device Connected" error.
I don't understand why I'm getting this error and I'm asking you for help.
Many thanks in advance

Hello,
the bluetooth connection doesn't work across screens. You can use virtual screens to maintain your connection across “views”.
An example:
