Advertising with timeout in loop

Question

Hello, 
 I want to design an application that advertises for X seconds. then stops advertising for Y seconds. then again starts advertising. I am trying to implement the same using app_easy_timer(); 
 
 as it is visible from the image, I have called stop_advertising_cb(). 
 
 in the stop advertising call back fuction I have stopped advertising using app_easy_gap_advertise_stop(); 
 Which is working fine. I can also see the next line printed on my uart consol. 
 Then I have initialised the same timer handler with, 
 start_advertising_again_cb(); 
 which is not working. 
 
 Have I missed something. I have currently set 10s in app_easy_timer();

Hi Sumo, Thank you for posting your question online. When you call the app_easy_gap_advertise_stop function, the app_on_adv_undirect_complete callback function will be called. So, for my implementation I worked on the ble_app_peripheral example and I declared the following: On user_callback_config.h file: .app_on_adv_undirect_complete = user_app_adv_undirect_complete, // Default Handler Operations
static const struct default_app_operations user_default_app_operations = {
 .default_operation_adv = user_app_adv_start, //user_app_adv_start
}; On user_peripheral.c file: timer_hnd app_adv_timeout_timer_used __SECTION_ZERO("retention_mem_area0");
#define START_ADV_IN_SEC 500	//5 seconds
#define STOP_ADV_IN_SEC 1000 // 10 seconds On user_app_init function I initiliaze the app_adv_timeout_timer_used: app_adv_timeout_timer_used = EASY_TIMER_INVALID_TIMER; The callback user_app_adv_start function will be called after default_app_on_init: void user_app_adv_start(void)
{
 // Schedule the next advertising data update
 app_adv_data_update_timer_used = app_easy_timer(APP_ADV_DATA_UPDATE_TO, adv_data_update_timer_cb);

 struct gapm_start_advertise_cmd* cmd;
 cmd = app_easy_gap_undirected_advertise_get_active();

 // Add manufacturer data to initial advertising or scan response data, if there is enough space
 app_add_ad_struct(cmd, &mnf_data, sizeof(struct mnf_specific_data_ad_structure), 1);
	//Check if Timer for Advertising is unitiliazed and initialize him again
 if( app_adv_timeout_timer_used != EASY_TIMER_INVALID_TIMER)
 {
 app_adv_timeout_timer_used = EASY_TIMER_INVALID_TIMER;
 }
 // Start the timer to stop advertising after 10seconds
 app_adv_timeout_timer_used = app_easy_timer(STOP_ADV_IN_SEC, stop_adv_cb);
 arch_set_extended_sleep(false);
 app_easy_gap_undirected_advertise_start();
	
} After 5 seconds, the stop_adv_cb callback function will be called: void stop_adv_cb(void)
{
 //Check if Timer for Advertising is unitiliazed and initialize him again
	if( app_adv_timeout_timer_used != EASY_TIMER_INVALID_TIMER)
	{
 app_adv_timeout_timer_used = EASY_TIMER_INVALID_TIMER;
 
	}
 app_easy_gap_advertise_stop();
	
} Then the user_app_adv_undirect_complete custom callback function will be called: void user_app_adv_undirect_complete(uint8_t status)
{
 // If advertising was canceled then wait 5 seconds and start advertising again
 if (status == GAP_ERR_CANCELED)
 {
 app_adv_timeout_timer_used = app_easy_timer(START_ADV_IN_SEC, user_app_adv_start);
 }

} With the SmartSnippets Toolbox, Power Profiler Tool I am able to see: So, keep in mind to initialize your Timer each time and that when you stop advertising to use the callback function. Note: You should use the app_easy_timer_cancel function if you establish a connection. Kind Regards, OV_Renesas
