Title Body

I am working on an iOS core Bluetooth application, I am able to connect with the BLE device using iPad3. I am able to reach to the block didDiscoverServices , but unable to proceed from here. My questions are ; How can I read characteristic from Bluetooth device? How can I read other information of Bluetooth device? Help me on this or provide any suggestion. Thanks Wilhelmsen for reply. I got the following from the mentioned block : [0] - Service : <CBConcreteService: 0x1769a0> UUID: Generic Attribute Profile [1] - Service : <CBConcreteService: 0x174470> UUID: Generic Access Profile [2] - Service : <CBConcreteService: 0x1744e0> UUID: Unknown (<00005301 00000041 4c505749 53450000>) Characteristic [0] - Characteristic : <CBConcreteCharacteristic: 0x15d410> UUID: Service Changed [0] - Characteristic : <CBConcreteCharacteristic: 0x1805b0> UUID: Device Name [1] - Characteristic : <CBConcreteCharacteristic: 0x1806a0> UUID: Appearence [0] - Characteristic : <CBConcreteCharacteristic: 0x183810> UUID: Unknown (<00004301 00000041 4c505749 53450000>) [1] - Characteristic : <CBConcreteCharacteristic: 0x1838a0> UUID: Unknown (<00004302 00000041 4c505749 53450000>) Now how to get the exact values from this Characteristic in didUpdateValueForCharacteristic block?
