Reply BLE pair params error

[MapleBay]

I'm using pc-ble driver-master for programming.
The hardware uses 52840 dongle and calls SD_API_V5.
After I successfully connected, I sent a pairing request using the sd_ble_gap_authenticate() function, The sd_ble_gap_sec_params_reply() function is then used in the "BLE_GAP_EVT_SEC_PARAMS_REQUEST" event.
But this function has an error message 0x07, I try to check or use other parameters to reply will get an error.

Genfeng, I totally missed to see that you mentioned using pc-ble-driver. Peer manager is not relevant for this.

You issue looks very similar to this.

Try turning off the Mass Storage Device (MSD) and check if this thread also have some useful suggestions.

Hi, Susheel Nuguru.

I use nRF Connect BLE app try to pair my dut. There seems to be nothing wrong with it. After that, I close the app and tried to program to realize the same action, but he reported an error, so now I am not sure if there is any problem. I also read the help document, and I think my process is OK. But the passing of parameters can be problematic.

This code, when run under "sd_ble_gap_sec_params_reply()", gets an error :0x10.

uint32_t pair(){
    uint32_t err_code;
    memset(&m_sec_params, 0, sizeof(ble_gap_sec_params_t));

    m_sec_params.bond = 0;
    m_sec_params.mitm  = 0;
    m_sec_params.lesc  = 1;                                // Use LE Secure Connection
    m_sec_params.io_caps = BLE_GAP_IO_CAPS_KEYBOARD_DISPLAY;   // Setting I/O capabilities may vary
                                                           // depending on your device
    m_sec_params.oob          = 0;                           // Do not use OOB
    m_sec_params.keypress     = 0;  // Disable keypress notifications
    m_sec_params.min_key_size = 7;                           // Minimum key size
    m_sec_params.max_key_size = 16; // Maximum key size
    m_sec_params.kdist_own.enc = 0;                           // Own encryption key distribution
    m_sec_params.kdist_own.id  = 0;  // Own identity key distribution
    m_sec_params.kdist_peer.enc = 0; // The encryption key of the peer end is distributed
    m_sec_params.kdist_peer.id  = 0;  // The identity key of the peer end is distributed

    err_code = sd_ble_gap_authenticate(m_adapter, m_connection_handle, &m_sec_params);
    if (err_code != NRF_SUCCESS)
    {
        DEBUG_PRINT("Failed to initiate authentication 0. Error: %d\n", err_code);
        return err_code;
    }
    
    err_code = wait_trigger_evt(BLE_GAP_EVT_SEC_PARAMS_REQUEST);
    if (err_code != NRF_SUCCESS)
    {
        DEBUG_PRINT("Failed to initiate authentication 1. Error: %d\n", err_code);
        return err_code;
    }
    return err_code;   
}



static void on_sec_params_reply(ble_gap_sec_params_t sec_params)
{   
    uint32_t err_code;

    err_code = sd_ble_gap_sec_params_reply(m_adapter, m_connection_handle,
                                           BLE_GAP_SEC_STATUS_SUCCESS, NULL, &m_keyset);

    if (err_code != NRF_SUCCESS)
    {
        DEBUG_PRINT("Failed to reply to security parameter request. Error: 0x%02X\n", err_code);
        return;
    }

}

Sorry to trouble you, I made a very low-level mistake that led to this problem, please close this post.

So sorry about than. Thanks for your halp!
