Hi,

I'm Using CC2642r with Simple_peripheral project.

I'm trying to set GAPBondMgr in order to get passkey on BLE connection and encryption .

i'm using this code :

uint8_t pairMode = GAPBOND_PAIRING_MODE_INITIATE;
uint8_t mitm = TRUE;
uint8_t ioCap = GAPBOND_IO_CAP_DISPLAY_ONLY;
uint8_t bonding = TRUE;

GAPBondMgr_SetParameter(GAPBOND_PAIRING_MODE, sizeof(uint8_t), &pairMode);
GAPBondMgr_SetParameter(GAPBOND_MITM_PROTECTION, sizeof(uint8_t), &mitm);
GAPBondMgr_SetParameter(GAPBOND_IO_CAPABILITIES, sizeof(uint8_t), &ioCap);
GAPBondMgr_SetParameter(GAPBOND_BONDING_ENABLED, sizeof(uint8_t), &bonding);

instead of getting passkey to set i got "Authentication failed" .

if there something i need to in project environment in order to be able to use these BLE features ( defines , includes ... )?

Thanks

Hi Hady,

Check out the GAP Bond Manager and LE Secure Connections section in the User's Guide with some GAP Bond Manager examples for different pairing methods.

You can also refer to the two security SimpleLink Academy labs; BLE Security Fundamentals and Advanced Security Features.

Thanks,
Elin

Hi Elin,

Thanks for the reply, i followed user guide step by step, still same problem.

Do you have any HEX file or project that you can share with me ? (example of project zero if it's possible)

Thanks,

Hady

Hi Hady,

Thanks for testing it again.

Yes, we have pre-compiled hex files for some of the projects in the SDK. There is a hex file for project_zero (unsecure) located in <SDK dir>\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\hexfiles.

Thanks,
Elin
