bond with iOS center and Master Control Panel

[steven]

hi, i add bond function on my project , now the Master Control Panel can work correctly(show the Confirm Box ) but the iOS app(on LightBlue),not show any Confirm Box for pairing.

In my opinion,the bond function is on the GAP. The BLE service and Characteristics no relation with bond.

can you give some suggestion ?

follow my code:

to redefine macro

#define SEC_PARAM_BOND                  1                                           /**< Perform bonding. */
#define SEC_PARAM_MITM                  1                                           /**< Man In The Middle protection required (applicable when display module is detected). */
#define SEC_PARAM_IO_CAPABILITIES       BLE_GAP_IO_CAPS_DISPLAY_ONLY

add the new macro for bond data

#define FLASH_PAGE_SYS_ATTR             (BLE_FLASH_PAGE_END - 3)                    /**< Flash page used for bond manager system attribute information. */
#define FLASH_PAGE_BOND                 (BLE_FLASH_PAGE_END - 1) 

and the ble event handle function

static void on_ble_evt(ble_evt_t * p_ble_evt)
{
    switch (p_ble_evt->header.evt_id)
    {
    ........
     case BLE_GAP_EVT_SEC_PARAMS_REQUEST:
            err_code = sd_ble_gap_sec_params_reply(m_conn_handle, 
                                                   BLE_GAP_SEC_STATUS_SUCCESS, 
                                                   &m_sec_params);
            break;
        case BLE_GAP_EVT_TIMEOUT:
            if (p_ble_evt->evt.gap_evt.params.timeout.src == BLE_GAP_TIMEOUT_SRC_ADVERTISEMENT)
            {
                nrf_gpio_pin_clear(ADVERTISING_LED_PIN_NO);

                // Go to system-off mode (this function will not return; wakeup will cause a reset).
                GPIO_WAKEUP_BUTTON_CONFIG(KEY_PRESS_BUTTON_PIN_NO);
                GPIO_WAKEUP_BUTTON_CONFIG(BONDMNGR_DELETE_BUTTON_PIN_NO);
                err_code = sd_power_system_off();    
            }
            break;
        case BLE_GAP_EVT_PASSKEY_DISPLAY:
                p_passkey = (char *)p_ble_evt->evt.gap_evt.params.passkey_display.passkey;
                success = nrf6350_lcd_write_string(PASSKEY_TXT, 
                                                   PASSKEY_TXT_LENGTH, 
                                                   LCD_UPPER_LINE, 
                                                   0);
                APP_ERROR_CHECK_BOOL(success);                
            break;
        case BLE_GAP_EVT_AUTH_STATUS:
        case BLE_GAP_EVT_CONN_SEC_UPDATE:
            break;
}

add the ble_bondmngr_on_ble_evt

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
    ble_bondmngr_on_ble_evt(p_ble_evt);
    ble_gls_on_ble_evt(&m_gls, p_ble_evt);
    ble_bas_on_ble_evt(&m_bas, p_ble_evt);
    ble_conn_params_on_ble_evt(p_ble_evt);
    on_ble_evt(p_ble_evt);
}

hi, i reference nordic sdk sample project,ble_app_gls.( Demonstrating the Blood Glucose Meter Profile) That have a bond function, but when i use LightBlue .it also no show the Confirm Box when connect.

Can anyone have idea about this?

Or that characteristic need Declare authorized_write/read?

[Ole Morten]

On iOS, no bonding will occur unless an app tries to read a characteristic that is protected. If you use LightBlue, this app will not do any such reads unless you specifically asks it to. To trigger bonding, you should therefore make sure to navigate the services/characteristics in such way that either a protected read or write is triggered, which again should trigger bonding.

[steven]

hi, thank you for your reply. you mean the LightBlue app ,it only show Confirm Box when read/write protected services/characteristics.

What in the world do you mean protected read/write services/characteristics? it is GATTS Read/Write Request with Authorization.

i try to program the Blood Glucose sample for it on battery service,but it don't show any message(confirm box)

ble_app_gls.zip

[Ole Morten]

No, authorization doesn't have anything to do with bonding, it's just a way for the application to know and authorize each read/write.

The protection I mean is the one set with the BLE_GAP_CONN_SEC_* macros. If you try to read any characteristic that is set as for example BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(), this will trigger bonding.
