CC2640R2F: Which BLE stack version do I use?

Hello,

I want to know which BLE stack version I use.

Where can I look it up?

Is the BLE stack version related to the SDK?

I already found this thread ( https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/546439/how-to-check-ti-ble-stack-version ) in the forum,

but if I look at the file location I only get: .../multi_role_cc2640r2lp_stack_library.

My SDK: 4.30.00.08

My CCS Version: 10.1.1.00004 

Thanks in advance.

Regards Sebastian
