Not exactly sure what you are looking for, but in addition to read the TRM, you can also take a look at the following links:

www.ti.com/.../swpb017a.pdf (think this is valid for CC13x2 as well)

Hi siri,

I studied Ti simplelink CC13x2 TI 15.4 - stack user's guide. Document mention that, To build the image with no security, perform the steps that follow:

In application maclib_secure_combo_cc1352.a file is there.

maclib_secure.a and maclib_secure_combo_cc1352.a, these two files are same or not ??

what exactly are you trying to do? are you trying to disable security in TI 15.4 Stack?

Also yes those 2 libraries are equivalent, the names have changed in some releases of the SDK

Hi Hector,
No , I am not trying to disable security in TI 15.4.
I have to prove encrypted data transmission is using application to my clients.

If using TI 15.4 Stack the easiest way of doing this is setting up a packet sniffer PACKET-SNIFFER-2 and take 2 sniffer captures one with security disabled and another one with security disabled.

The fastest and easiest way of enabling/disabling security is by going to the file config.h and set "CONFIG_SECURE" to true if you want security and false if you want to remove security.

If you are using security, TI 15.4 Stack uses AES 128 for encryption and a 32 bit MIC(Message Integrity Code) by default. The default security key is defined by KEY_TABLE_DEFAULT_KEY in config.h
