Hello Indragie,

With some iPhones (got the problem with a 4S, a 5 and a 6), the Bluetooth devices enter a connect/disconnect loops:

Found device: Victor's iPhone
Victor's iPhone disconnected with error: Error Domain=CBErrorDomain Code=6 "The connection has timed out unexpectedly." UserInfo=0x60000006c040 {NSLocalizedDescription=The connection has timed out unexpectedly.}

This is repeated infinitely, with both Bluetooth icons (on the Mac and on the iPhone) blinking, indicating that the connection is indeed established for a few milliseconds.

I tried unpairing, turn off and on the Bluetooth, rebooting, resetting the iPhone. Nothing changes.

Any idea what is happening there ?

I'm running both INDANCSMac (on a MacBook Pro 15'' mid-2014, OS X 10.10) and INDANCSiPhone (on an iPhone 4S, 5 and 6, iOS 8.1.3) applications.

In INDANCSClient.m didDiscoverCharacteristicsForService the array returned here...

NSArray *characteristics = service.characteristics;

...is empty, causing a crash.

Were looking to create a service that finds nearby users using bt autonomously , your lib looks on the surface like something that might solve our problem , is it possible to use this lib to find nearby devices ( all we need is a single unique identifier )

When I run the mac app, I get the error 'ObjectiveKVDB/ObjectiveKVDB.h' file not found
