Unable to create Osal Timer event CC2541 BLE Central application

Arjun Veneshetty

I've a question regarding the function "osal_start_timerEx", I've created a timer event as shown below:
osal_start_timerEx( simpleBLETaskId, TIMER_UPDATE_EVT, 250 ); (received errcode SUCCESS here)

but I don't see this event getting triggered in function "SimpleBLECentral_ProcessEvent()". Can anyone please explain me the reason?

Sample code:

SimpleBLECentral_ProcessEvent( uint8 task_id, uint16 events ) -

if ( events & TIMER_UPDATE_EVT )
{
LCD_WRITE_STRING( "Test...", HAL_LCD_LINE_3 );

osal_start_reload_timer(simpleBLETaskId, TIMER_UPDATE_EVT, 250);
}

Hi Arjun,

You would need to start the timer at some point outside the timer event, otherwise the event will never be triggered and the timer never started. Perhaps in the task Init().

Also you don't need to re-start the _reload_timer, because it does what it advertises. Unless you stop it, of course.

Best regards,
Aslak

Thanks Aslak,

I was calling this function - osal_start_timerEx( simpleBLETaskId, TIMER_UPDATE_EVT, 250 ); in SimpleBLECentral_Init( uint8 task_id ) function and trying to get the callback in SimpleBLECentral_ProcessEvent() function wth event set to ( events & TIMER_UPDATE_EVT ) but I'm not getting this event at all!

Hi Arjun,

is HAL_TIMER = TRUE under the preprocessor options?

Thanks Lenio,

I've added HAL_TIMER=TRUE under the preprocessor options and also changed the following lines in hal_board.cfg.h -

/* Set to TRUE enable H/W TIMER usage, FALSE disable it */

#ifndef HAL_TIMER

#define HAL_TIMER TRUE // Changed from FALSE

#endif

Still, I didn't get the callback. Anyhelp is highly appreciated.

How are the constants defined under SimpleBLECentral.h? You should see something like this:

/*********************************************************************

* CONSTANTS */

// Simple BLE Central Task Events

#define START_DEVICE_EVT 0x0001

#define START_DISCOVERY_EVT 0x0002

#define TIMER_UPDATE_EVT 0x0004

Thanks Lenio,

Yes... I've exactly the same. My first test didn't flash properly I guess. I recompiled and flashed again and it worked. Thank you very much.
