I know this questions has been asked multiple times, But My case is slightly different from others. I am successfully able to connect and receive values from a heart rate device within my app (iPhone 5, iPhone 4S, iPad 3) with different ios versions. But in client end, Its not working at all, dont know why.
Also i debug the code again today and its working fine with iPhone 5,5C and iPAd 3 but in iPhone 4S with iOS 6.1.3, I got CBCentralManager.state = 2 ( is not powered on) May be this is the issue in client ends too?.
Can someone explains me what is happening? If same code runs fine on iPhone5,5c,iPAd 3 then why not in clients end as well as now mine 4S ? Can someone point me what is happening as now i am totally frustrated with this. Any guidance will be really appreciable. Thanks
iPhone 4S does not support BLE. And central/peripheral manager state == 2 actually means 'Unsupported'. 'Not powered on' state is 4. Take a look at apple core bluetooth reference: https://developer.apple.com/Library/ios/documentation/CoreBluetooth/Reference/CBCentralManager_Class/translated_content/CBCentralManager.html#//apple_ref/c/econst/CBCentralManagerStateUnknown
