ECDH in BLE-STACK 1.5.0 for CC2540 and CC2541

As I know, CC254x doesn't support Bluetooth 4.2 Core Specification. You can refer to the discussions in e2e.ti.com/.../1370855

As I know,

BLE-Stack 1.5.0 is a maintenance release and provides most up-to-date and robust Bluetooth 5.0 SW protocol stack while maintaining the same Bluetooth 4.0 defined feature set and API capability to the previous BLE-Stack 1.4.2 release. It is strongly recommended that all ongoing and new development projects update to BLE-Stack 1.5.0 release. For further details on this update, see the release notes and migratoin guide in the BLE-Stack 1.5.0 SDK installation folder.

Is there an official people to indicate whether the current BLE-STACK 1.5.0 (CC2541) supports ECDH ?
Our customers need to know this answer.

Thanks.

Hi Mars,

BLE-Stack v1.5.0 is BT5.1 qualified although does not contain any of the optional BT4.2-5.1 features. It's limited to BT4.1 functionality.

Hi Joakim,

I don't understand you provide information, So the conclusion is BLE-Stack v1.5.0 does not support Elliptic Curve Diffie-Hellman (ECDH) ?

------------------------------------------------------------------------------------------------------------

As I know, qualified is BT5.0 not BT5.1

and

According to TI webpage ( https://e2e.ti.com/blogs_/b/connecting_wirelessly/archive/2016/08/11/how-bluetooth-4-2-can-help-enable-product-security)

Bluetooth 4.2 Core Specification. including Secure pairing based on ECDH.
