I'm currently working on developing an app that is heavily dependent on iBceaons.
I managed to create a beacon region which wakes up the app process in the background for 10 seconds when entering the region.
The next step is making phone it self advertise when it enters the region while in background
Currently while the app is open it keeps ranging and transmits as a beacon while its in a region
where as when the app is in the background , it ranges for 10 seconds but doesn't transmit as a beacon when it enters a region
so is there a way to allow the phone to transmit as a beacon when its in the background when it enters a region ?
I already had a look into Apple's background Bluetooth which mentioned that the advertising packet is differs when transmitting in the background. I have also looked at This Solution but this solution doesn't use core location so it can't wake the app when entering a region
