CCS/LAUNCHXL-CC26X2R1: How does the Callback parameter in GapAdv_create() work?

Tool/software: Code Composer Studio

Dear team,

I am trying to wrap my mind around the interplay between TI-RTOS, iCall, BLE protocol stack. I believe I understand how GapAdv_create() works, but I wanted to make sure that I am not getting something backwards. When GapAdv_create() is called the SimplePeripheral_advCallback() is invoked which then sends a message to the TI-RTOS message queue. I am familiar with the situation when an event occurs in the protocol stack which is then sent to application. Is GapAdv_create() a case where information, through the creation of an advertisement set, is sent to the protocol stack from the application.

Best regards,

Hi Connor,

Please refer to the BLE API documentation about GapAdv_create().

Thanks,

Dear Elin:

I have reached that resource prior to my post, but it does not answer my question. What it is briefly explained, but not elaborated on is how the callback function works when GapAdv_create() is called. The following snippet is what I am in reference to:

How do these various events get passed into the callback function? Are these events from lower in the protocol stack?

Best regards,

Connor Desmond

Hi Connor,

Apologies for the delay.

There is a lot of information about that in the GAP chapter of the User's Guide, especially the GAP Advertiser.

Thanks,
Elin
