Hi All,
 
I also have this problem occasionally. My app is built in iPhone5 with iOS 7.0.

I have an iOS app written in Objective-C that works, and am now working on an alternative, written in Swift.  I can connect to my BLE device, but the call to discoverServices on the CBPeripheral never results in the callback to didDiscoverServices.  My BLE delegate class implements CBPeripheralDelegate (along with CBCentralManagerDelegate):

class foobar: NSObject, CBCentralManagerDelegate, CBPeripheralDelegate {


The callback method is defined as:


func peripheral(peripheral: CBPeripheral!, didDiscoverServices error: NSError!) {


The app is running in an iPhone 4s running iOS 7.1.2.   I have the Bluetooth Diagnostics profile installed, and the log produced shows that the service discovery is happening and that a message is going back to my app:

09:17:58.388 XpcConnection.cpp:1700    sendMsg              XPC        Notice     Sending XPC message "CBMsgIdPeripheralServicesDiscovered" to session "com.onsetcomp.testapp-central-5033-180"

But the didDiscoverServices callback is never invoked.  As I said, this is working in another app, written in Objective-C, with this same BLE device and iPhone, so I’m assuming I’ve just overlooked something silly.  Ideas?
