Hello Joakim,
We have a BLE application which normally runs in the background. When an advertising BLE device comes within range, we want our app to be woken up and interact with the BLE device. Can we setup a callback/event in Core Bluetooth Framework to do so? Are there timeout on connection requests when app runs in background?
Thanks in advance.
Kind regards,
Jeff

Hi zz_zhang,
That is correct. The connection request will be pending until you cancel it. This can be quite useful if you want to connect to a device as soon as it comes within range. There is no timeout on connection requests. The system tried to connect to the peripheral for as long as you want (days, months, years) or until you cancel it.
Thanks,
Joakim

After a shot time, if I make the BLE device in advertizing, the connection automatically establish without a button pressing.
