I want to decrypt some packets caught in LE Audio(Using the sample:nRF5340 Audio application), but need the link-key.

According to this case, I add these to prj.conf to get the link-key.

CONFIG_BT_LOG_SNIFFER_INFO=y
CONFIG_BT_DEBUG_LOG=y

Get the link-key:

I use the link-key for decryption but failed, and I notice the answer of this case change the link-key.

The link-key in log need to transform?How to transform it?

Please help! Thanks!

  • Hi dejans,

    Sorry, English is not my native language, so my expression may not be clear enough.

    Yes, the two links lead to the same one.

    The answer in the link shows different link-key between log and Ellisys panel, why the link-keys are different?

    I want to know:

    Can the link-key printed in log be directly used for decryption?

    If no, how to transform the link-key that can be used for decryption.

    Thank you for your patience!
