The function SecLib_CcmStar is referenced in the 802.15.4 MAC PHY Software Reference Manual Rev.6 but I can not find it in any source or compiled library of Beekit Rev 3.0.2. Is it available somewhere else?
No, the CCM* function implementation is not available. Please review my previous answer because I've updated it. The MMCAU is public available, I've posted the link so you can download it.
