Have you tried  ‘scanForPeripheralsWithServices:options:’ specifying @{CBCentralManagerScanOptionAllowDuplicatesKey: @YES} for options?

But I don’t want to connect again. I just want to be notified that the peripheral is available, so I can display it in a list. If iOS didn’t automatically connect without request or consent, I would receive advertising events…

Thanks

You can call -connectPeripheral:options: again from the -centralManager:didDisconnectPeripheral:error: delegate method, to make iOS call your delegate method again when the device is reconnected again.

Hi all,

If I:
  • Scan for peripherals
  • Connect to a peripheral
  • (pair)
  • Turn off the peripheral
  • Turn on the peripheral

Then the peripheral will automatically connect to iOS, but no delegate method is called. That is because iOS didn’t receive an advertising packet so didn’t call didDiscoverPeripheral but also the connection wasn’t requested by the App so didConnectPeripheral isn’t called either. I still want to know about the presence of the device though. The only way I can see I can do that is by repeatedly calling retrieveConnectedPeripheralsWithServices. Surely iOS should provide some delegate method to be notified when a device connects to iOS rather than directly to the App? Personally I think it should call didConnectPeripheral, but it doesn’t…

Thanks
Nick
