In Linux kernel code how to disable CTKD (Cross Transport Key Derivation) feature for Bluetooth-BLE
When we connect and bond BLE, link keys are generated for both BLE and BREDR. This because of CTKD (Cross Transport Key Derivation).
Query: In Linux Kernel code, with Bluez 5.61, I want link keys to be generated separately during BLE and BT connection. How can I disable this CTKD feature? Is there any flag that will help to disable this?
My attempt: I tried to comment the code that generates BREDR link key during BLE connection, but this way has a impact during BREDR connection.
