CC2640R2F: BLE 5.0 Pairing Issue.

Neville Frank

Part Number: CC2640R2F

Hi,

I am using BLE5 Project Zero code from SDK :simplelink_cc2640r2_sdk_3_30_00_20 for my project.

I am facing some issues with pairing. In the project we are using custom profile with 4 Characteristics, One Characteristic has permission : GATT_PERMIT_AUTHEN_READ|GATT_PERMIT_AUTHEN_WRITE and properties: GATT_PROP_INDICATE.

I am able to pair and communicate with Samsung S10, but same pheripheral device not able to communicate with one plus 3.

following are GAP bond settings.

uint8_t pairMode = GAPBOND_PAIRING_MODE_WAIT_FOR_REQ;
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);

Can you please help me with this issue.

Thanks and Regards,

Neville

Hi Neville,

I am going to ask a concerned engineer to comment. Please bear with me.

Hi Neville,

1) Can you specify what you mean by "not able to communicate"? Does the connection succeed? Does the device crash when this happens?

2) Please capture and post a sniffer log of the failed pairing process.

Hi Marie,

In both devices connection was established, but at the time of pass key entering device does not get paired for OnePlus 3 phone.

I am currently not having ble sniffer device.

Thanks,

Neville

What APP do you use on OnePlus 3 phone to do pairing and bonding with CC2640R2 BLE5 Project Zero? I would suggest you to make sure CC2640R2 BLE5 Project Zero is completely removed from your OnePlus 3 phone BLE device settings to do the test again.
