how to get the number of bonding informations stored.......?

[iqbalpalemad]

Hai

i am using mbed to program my nrf51822. i need to implement bonding in my application. for that i am using securitymanager. and i have changed DEVICE_MANAGER_MAX_BONDS to 24 in device_manager_config.h. now i am able to store 24 bonding information. but when i bond a 25th device nrf51822 gets hang. so i need to get the number of bonds at any time and i need to clear that info when it is equal to DEVICE_MANAGER_MAX_BONDS. so is there any way to get the number of bonds............?

Hi,

The device manager does not expose an API for retrieving number of stored bonds in flash directly, but you can use the dm_service_context_get() function which will return NRF_SUCCESS for stored entries.

uint8_t bonds_count_get(void)

{

   uint32_t                       err_code;

   uint8_t                        cnt = 0;

   dm_handle_t                    p_handle;

   static dm_service_context_t    service_context;

   memset(&p_handle, 0, sizeof(dm_handle_t));

   for (uint8_t i=0; i < DEVICE_MANAGER_MAX_BONDS; i++)

   {

        err_code = dm_service_context_get(&p_handle, &service_context);

        if(err_code == NRF_SUCCESS)

        {

             cnt++;

        }

        else if(err_code == NRF_ERROR_INVALID_STATE)

       {

              APP_ERROR_CHECK(err_code);

        }

       

        p_handle.device_id++;

    }

return cnt;

}
