ONLY FOR MAGICIANS!(-..mentalism..--)
Remember you need bluetooth activate.You need 2 decices, see the screenshot for the instructions. Deactivate (Receiver Mode) "Time Out" on display setting. The first time and everytime you change the Calculator/Receiver mode maybe you need to restart the application in the "Receiver Mode" to sync the bluetooth. ONLY FOR MAGICIANS. GOOD FUN!</br>
