app_easy_gap_advertise_stop

Hello support team,

I'm trying to understand how the SDK works.

Using example ble_app_barebone.

I'm trying to have the device running in 2 states :

state 0 : advertising
state 1 : doing nothing

为此我修改上述项目that way :
in function adv_data_update_timer_cb() -- timer callback : I'm switching state based on an internal counter
When counter reaches the expected value, I change state and ask for adv stop:

myStatus is a global variable

uint8_t myStatus __attribute__((section("retention_mem_area0"), zero_init)); //@RETENTION MEMORY uint8_t nb __attribute__((section("retention_mem_area0"), zero_init)); //@RETENTION MEMORY static void adv_data_update_timer_cb() { nb++; if (nb==2) { myStatus=1; // evite la relance app_easy_gap_advertise_stop(); } else if (nb>=4) { myStatus=0; nb=0; } // If mnd_data_index has MSB set, manufacturer data is stored in scan response uint8_t *mnf_data_storage = (mnf_data_index & 0x80) ? stored_scan_rsp_data : stored_adv_data; // Update manufacturer data mnf_data_update(); // Update the selected fields of the advertising data (manufacturer data) memcpy(mnf_data_storage + (mnf_data_index & 0x7F), &mnf_data, sizeof(struct mnf_specific_data_ad_structure)); // Update advertising data on the fly app_easy_gap_update_adv_data(stored_adv_data, stored_adv_data_len, stored_scan_rsp_data, stored_scan_rsp_data_len); // Restart timer for the next advertising update app_adv_data_update_timer_used = app_easy_timer(APP_ADV_DATA_UPDATE_TO, adv_data_update_timer_cb); }

than in user_app_adv_start I do not call app_easy_gap_undirected_advertise_start when myStatus == 1

void user_app_adv_start(void) { //arch_printf("user_app_adv_start"); /*SB*/ // 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); /*SB*/ if (myStatus==1) { return; } 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); app_easy_gap_undirected_advertise_start(); }

The result is not what I expected as it finishes in NMI_HandlerC.

Could you help me understanding what I did wrong

Thanks
