Platform doesn't support Bluetooth Low Energy Central/Client role

Question

In settings I see Bluetooth is turned on. But

- (void) centralManagerDidUpdateState:(CBCentralManager *)central

returns

central.state == CBCentralManagerStateUnsupported

What does it mean?

iPad model mc796rs/a and iOS 7.0.3

Answer 1

The iPad 2 does not have a bluetooth 4 (low energy) chip, so CBCentralManagerStateUnsupported means that it is not supported.
