Hello everyone.

I have the following problem.

When I put in the code blecen_Scan the timer 1s stopped working.

Has anyone ever had a similar problem?

Ok, perhaps now I understand the question. If you initiate the blecen_scan in the create function, it will enter this state of scanning until it is interrupted. You will have to implement the blecen_scan(No scan) some where to interrupt/break it, then those timers will continue to work and count. Alternatively, don't start the scan in the create function, put it in an interrupt handler.

For example:

void app_create(void)

{

    bleprofile_Init(bleprofile_p_cfg);

    bleprofile_GPIOInit(bleprofile_gpio_p_cfg);

    // Enable Button Interrupt

  

    // register to process peripheral advertisements, notifications and indications

    blecm_RegleAdvReportCb((BLECM_FUNC_WITH_PARAM) advertisement_handler);

    blecen_Scan(NO_SCAN);

    bleprofile_regTimerCb(app_fine_timer, app_timer);

    bleprofile_StartTimer();

}

void app_fine_timer(UINT32 arg){}  //do nothing

void app_timer(UINT32 arg){

     ble_trace0("1s has elapsed");

}

The above will allow the timer to run, and if I apply an interrupt, the state will change to that of scanning. You may also want to implement a

callback when the scanning process ends, then the device will return to counting again. Insert some traces to show the executions.

Are you referring to the SW 1s application_timeout? And where did you put blecen_Scan?

In any case, I assumed that you are working on a client application and I would like to refer to the hello_client application.

If P0 is pressed for 6s, then the client_app will deemed it as an interrupt and proceed to call the handler, subsequently entering

a high duty scanning state:

{

    ble_trace0("Stop adverts and start high scan");

    bleprofile_Discoverable(NO_DISCOVERABLE, NULL);

    blecen_Scan(HIGH_SCAN);

}

Do refer to the hello_client app on how to deploy blecen_Scan.

Did you perform the kill_timer function first before you start it?

// change timer callback function.  because we are running ROM app, need to

// stop timer first.

    bleprofile_KillTimer();

    bleprofile_regTimerCb(hello_client_app_fine_timer, hello_client_app_timer);

    bleprofile_StartTimer();

Yes, 1s application_timeout. I put blecen_Scan in the "create" function.

I do not use the killtimer function, but using her did not work.

The timer will worl if the blecen_scan function is commented on.

My app need scan beacons advertisements and send data via UART. Blecen_scan is the better way to do 20737 scan beacons?
