I want to determine the BLUETOOTH ADDRESS for an iPhone or iPad from within an app on said device. But I didn't find any API that will return the BLUETOOTH ADDRESS or name. Please help me for finding the BLUETOOTH ADDRESS in iOS7.
@JeanetteMueller and @tleavy86 no, not a bug, harpher is right about it
@chrismaddern yes: free to use, but I was requested to leave some "Original source code courtesy John from iOSDeveloperTips.com"
@jontyankit I will investigate with CoreBluetooth maybe
For all: sorry, I never received any email alert for your comments, so I didn't notice for months there were comments here.
