Hi, can FRDM-KW41Z be used to implement A2DP connection to a Bluetooth headset? Are there any software examples for reference?

Thanks.

Hello,

Sorry for the inconvenience this might cause you but it does not support it.

The KW41 supports BLE 4.2 and the A2DP it’s a Bluetooth classic profile.

Hello,

So, the KW41Z can't be used to communicate with the headset of bluetooth classic, and it is not compatible with HFP(Hands-free Profile) either, is it right?

Thanks a lot.

Hello,

You are right, and the reason why is because BLE is not intended to be used for audio streaming; it has the sleeping times to be low power and the packet size tend to be small.

Sorry for the inconvenience this might cause you.
