Scenario:

Design is to detect probe. If no probe absent, enter Sleep/Low Power Mode for 6 seconds and repeat

If probe is present, then Enable BLE Timer for 1sec.

On first entry to 1 sec timer call back. Abort Low Pwer mode.

Measure probe,  enable ADVertisement and wait for pairign etc.

Issue: We do not get registered even call back for BLECM_APP_EVT_LINK_UP alone

But all other event callback (BLECM_APP_EVT_LINK_UP and BLECM_APP_EVT_ADV_TIMEOUT ) are called back properly.

Note: Tried executing without calling

        bleprofile_enteringDiscLowPowerMode(DEV_LPM_DISC_LOW_POWER_MODES_SLEEP); and

        bleprofile_abortingDiscLowPowerMode(DEV_LPM_DISC_LOW_POWER_MODES_SLEEP);

in code

Then, in this case all 3 registered app event are called.

Code:

On create()

{

.................

    bleprofile_Init(bleprofile_p_cfg);

    bleprofile_GPIOInit(bleprofile_gpio_p_cfg);

.

.......

// register connection up and connection down handler.

    bleprofile_regAppEvtHandler(BLECM_APP_EVT_LINK_DOWN, cookp_connection_down);

    bleprofile_regAppEvtHandler(BLECM_APP_EVT_LINK_UP, cookp_connection_up);

    bleprofile_regAppEvtHandler(BLECM_APP_EVT_ADV_TIMEOUT, cookp_advertisement_stopped);

.............

    // Low powe mode initialize

    devlpm_init();

    devlpm_registerForLowPowerQueries(cookp_lpm_queriable, 0);

    bleprofile_enteringDiscLowPowerMode(DEV_LPM_DISC_LOW_POWER_MODES_SLEEP);

}

UINT32 cookp_lpm_queriable(LowPowerModePollType type, UINT32 context)

{

  if(!cp_lp_abort){

    if(cookp_probe_chk()){

       ble_trace0("LPQ No");

       cookp_reg_timer();

       return 0;

    }

    else {

     ble_trace0("LPQ yes");

     return 1000000 * 6;

   }

  }

  return 0;

}

void timer_cb()

{

      if(!cp_lp_abort){ /* if probe detected on wake up */

       cp_lp_abort = TRUE;

       bleprofile_abortingDiscLowPowerMode(DEV_LPM_DISC_LOW_POWER_MODES_SLEEP);

      }
