Tian’s got it right on all counts. When a device connects, we don’t have any idea what service(s) it’s interested in. So, in order to be safe, we’d have to wake up every app with a CBPeripheralManager, in case it’s the “right” one. This is incredibly wasteful from a power perspective and fairly inelegant to boot.

In the end, it seemed natural that if an app is hosting a service, it could wait to find out about a remote device once it began “using” the service, via a read, write, or subscription event.

Thanks for the history and information, Tian!  

It does make sense, I suppose...

Hi Justin,

Currently there is no public API to get notification when a central connected to peripheral. If you find that’s something you really need, please file an enhancement request on http://bugreport.apple.com .

When CBPeripheralManager first introduced in iOS 6 beta, there was a delegate callback when the peripheral get connected. However, in the later release, the team made the argument that since a peripheral (iOS) can host multiple services from different apps and the central may not interested in your app’s service, they decided to remove that delegate callback. I’d say the possibility to bring that API back is really small.

Best Wishes,
Tian

Greetings!

I have a peripheral app which is working fine.  

I want to be notified when a central connects to my peripheral.

I understand there is a didSubscribeToCharacteristic which works when a central subscribes, but I would like a notification on the connection itself.  (like didConnectToPeripheral on the central side)


Am I missing something in the documentation?  I can't seem to find this information anywhere!


Thanks in advance,
Justin
