The core specification for Bluetooth 4.0 defines GATT procedure Read Long Characteristic Values, which is used to request a characteristic value longer than the limit of ATT_MTU – 1 bytes.
Is this feature supported by CoreBluetooth( and iOS)? The peripheral device is a TI CC2541 dev kit.
Yes it is supported on iOS6 anyway – if you request a read on a characterstic that is set up to be longer than 20 bytes then iOS will return that longer data.
