Pairing with Smart RF Board as peripheral and PC Application as central

Ramesh Kumar Jayaraj

Other Parts Discussed in Thread: CC2540, CC2640

Hi,

By following the same Bond Set Param and HCI Commands,  now I cannot able to pair a RF board with a PC Application.

When we are trying to connect with PC application with CC2540 USB dongle and Smart RF Board with CC2640, the connection has been done successfully. For Pairing procedure we are done the following steps.

In CC2640, RF board has been flashed from Simple BLE central project initialize as Peripheral.

Pairing Mode = GAPBOND_PAIRING_WAIT_FOR_REQ
GAPBOND_MITM_PROTECTION = Enabled
GAPBOND_BONDING_ENABLED = Disabled
GAPBOND_IO_CAPABILITIES = Display only

In PC App with CC2540 USB Dongle initialize as central role,

Pairing Mode = GAPBOND_PAIRING_DONT_WAIT_FOR_REQ
GAPBOND_MITM_PROTECTION = Enabled
GAPBOND_BONDING_ENABLED = Disabled
GAPBOND_IO_CAPABILITIES = Keyboard and Display

But, the Authentication has been end with failure as wrong passkey.

Since we have to exchange the passkey as displaying in RF board and enter the value in PC application to pair the devices.

Kindly help me on, to understand the issue and guide to make the Authentication success with proper Passkey exchange.

Regards,

Ramesh Kumar

    Hello Ramesh,

    Can you provide a BLE air sniffer trace of the pairing?

    Also, please clarify: "Simple BLE central project initialize as Peripheral".

    Best wishes

    HI JXS,

    Please find the attached trace with two CC2540 dongle in BTool with the same set of Bond Parameter set and executed for pairing.

    Peripheral:

    Pairing Mode = GAPBOND_PAIRING_WAIT_FOR_REQ

    GAPBOND_MITM_PROTECTION = Enabled

    GAPBOND_BONDING_ENABLED = Disabled

    GAPBOND_IO_CAPABILITIES = Display only

    Central:

    Pairing Mode = GAPBOND_PAIRING_DONT_WAIT_FOR_REQ

    GAPBOND_MITM_PROTECTION = Enabled

    GAPBOND_BONDING_ENABLED = Disabled

    GAPBOND_IO_CAPABILITIES = Keyboard and Display

    The Authentication has been completed successful without waiting for Passkey Update.

    When I am executing the same with Smart RF board (Peripheral) and PC Application (Central) the authentication has been ended with wrong passkey failure.

    Hi Ramesh,

    It looks like you attached the file for the successful authentication. Could you please attach the file for the failure case?

    Which version of the BLE Stack SDK are you using for the CC2640?

    HI,

    Please find the failure sequence during the Authentication with PassKey exchange getting failure.

    We are using the 2.1 version of the BLE stack is using in CC2640 smart RF project.

    Also we are using the Peripheral Sample project we are using in the Smart RF board.

    We have captured the sniffer logs for the packets available in air. Also I have attached Tx and Rx packets captured from PC application.

    Kindly go through the logs and let me know, to make the Authentication complete with Success by exchanging the PassKey.

    Hi Ramesh,

    I am unable to recreate your problem on my side so I have a few questions to make sure we are using identical setups:

    1. What is the exact version number of the BLE Stack you are using on your CC2640 (2.1.0, 2.1.1)?
    2. What is the name of the sample project you are using for the CC2640?
    3. What is the name of the sample project you are using for the CC2540?
    4. What modifications were made to each project?
    5. Are you using the default passcode for pairing?
