I create a sample project for Bluetooth and arduino and i have 7 page and each one need send and receive via Bluetooth
i insert AStream_NewData in each one and when project start only one page receive data and another did not receive any data.
i check AStream_NewData with debug point in another page , and i know in another page AStream_NewData not going to start or recive data.
why ?

and sometime i get error Broken pipe bt socket closed, read return: -1
