I am new to the bluetooth technology, i want to use CC2540 for audio data transfer. CC2540 can support A2DP for audio data transfer.
Latest BLE stack can support A2DP?.
What are the profiles supported by latest BLE stack?
Thanks in advance.

Hi,
Audio streaming is explicitly NOT supported in BLE, as the BLE protocol was not designed to do this. A2DP is therefore only supported in "classic" Bluetooth, not BLE.
Version 1.2 of our BLE stack supports the following profiles:
- Blood Glucose
- HID over GATT
- Proximity
- Find me
- Health Thermometer
- Heart Rate Sensor
- Time
- Alert Notification
- Battery Status
As well as some custom profiles defined by TI.
There profiles are all GATT-based, as opposed to "traditional" profiles, which usually use their own custom protocols.
If you look at the Bluetooth SIG's list of adopted specs at https://www.bluetooth.org/Technical/Specifications/adopted.htm, the profiles supported in BLE are the ones listed in the "GATT-based specifications" table, while the profiles listed under "Traditional profiles" (including A2DP) are only supported in "classic" Bluetooth (including dual-mode devices like the CC2564). As CC2540/41 are BLE-only devices, they can only support the GATT-based profiles.
Best regards,
Karl
