RTOS/CC2650: What is difference between Establishing a Link and Pairing?

Arun Joe

Part Number: CC2650

Tool/software: TI-RTOS

I want to know what is the difference between, establishing link defined in the GAP Role and the pairing option in the GATT Profile?

I get the pairing option only(in BLE scanner app) when characteristics that require authentication is accessed.

Is this how it is supposed to work? why is there no pairing option while connecting?

What is the function of GAP_PAIRING_REQ_EVENT event of gapRole_processGAPMsg(gapEventHdr_t *pMsg) function and when is this accessed?

Hello Arun,

In BLE connections are independent of the optional Security Management Protocol in which LE Pairing is used. You can find details about connections with our SimpleLink Academy BLE Connections lab. For Security, I recommend reviewing the GAP Bond Manager section of the SIMIPLELINK-CC2640R2-SDK BLE stack documentation.

I couldn't find any documentation on GAP Bond Manager in the link you have given.
Please answer my question regarding the simple peripheral example given below,

What is the function of GAP_PAIRING_REQ_EVENT event of gapRole_processGAPMsg(gapEventHdr_t *pMsg) function and when is this accessed?

Hello Joe,

You can find the GAP Bond Manager documentation here: software-dl.ti.com/.../gapbondmngr.html

You don't need to be concerned with the GAP_PAIRING_REQ_EVENT since this is handed by the bond manager. The documentation describes the interaction with the application.
