RE: SDK15.0 LESC

Hi,

As far as I can see, the LESC support in Peer Manager have had major refactoring and modifications from SDK 15.0.0 to SDK 15.1.0. There are also some additions to the library between SDK 15.1.0 and SDK 15.3.0, but after this there seems to be no changes to the LESC module until current SDK version (17.0.2).

Since this is within the same major version of the SDK, maybe you are able to do the migration? If the libraries were not in production at the time, there is no guarantee from our side that the libraries are thoroughly tested or verified, and we will not have tested older versions of the library when releasing new SDK versions. That said, it is always your responsibility as a product developer to verify that the libraries and modules provided in the SDK are functioning correctly in your application.

I'm not aware of more examples showing encryption with LESC, but you can have a look at the message sequence charts in the softdevice documentation: Peripheral LESC Pairing.

Best regards,
Jørgen
