scanner

Hi.
I want to implement the BLE scanner function.
The gapm_adv_report_ind_handler event does not occur.
I implemented the source code as below.
Please check the code.
Is there a simple scanner sample project?

EXTERN const struct ke_msg_handler app_default_state[] =
{
....
{GAPM_ADV_REPORT_IND, (ke_msg_func_t)gapm_adv_report_ind_handler},
...
}

int gapm_adv_report_ind_handler (ke_msg_id_t是否,struct gapm_adv_report_ind *param, ke_task_id_t dest_id, ke_task_id_t src_id)
{
app_adv_report_ind_func(param);
return (KE_MSG_CONSUMED);
}

void app_set_dev_config_complete_func(void)
{

// We are now in Initialization State
ke_state_set(TASK_APP, APP_DB_INIT);

// Add the first required service in the database
/* if (app_db_init())
{
// No service to add in the DB -> Start Advertising
app_adv_start();
}
*/
app_start_scanning();

return;
}

void app_start_scanning(void)
{
arch_printf( "app_start_scanning \n");
struct gapm_start_scan_cmd *msg = KE_MSG_ALLOC(GAPM_START_SCAN_CMD, TASK_GAPM, TASK_APP, gapm_start_scan_cmd);
msg->mode = GAP_OBSERVER_MODE; //GAP_GEN_DISCOVERY;
msg->op.code = GAPM_SCAN_ACTIVE; //GAPM_SCAN_PASSIVE;
msg->op.addr_src = GAPM_PUBLIC_ADDR;
msg->filt_policy = SCAN_ALLOW_ADV_ALL; //SCAN_ALLOW_ADV_WLST; //SCAN_ALLOW_ADV_ALL;
msg->filter_duplic = SCAN_FILT_DUPLIC_EN;
msg->interval = 4000; //10;
msg->window = 4000; //5;
ke_msg_send(msg);
return;
}

//App_scanning_completed_func is called as soon as app_start_scanning is called.
void app_scanning_completed_func(void)
{
arch_printf( "app_scanning_completed_func \n");
// app_start_scanning();
}

int gapm_cmp_evt_handler(ke_msg_id_t const msgid, struct gapm_cmp_evt const *param, ke_task_id_t const dest_id, ke_task_id_t const src_id)
{
switch(param->operation)
{
case GAPM_SCAN_ACTIVE:
case GAPM_SCAN_PASSIVE:
{
app_scanning_completed_func();
break;
}
}
}
