BLE Advertising after light sleep

[leogs01]

When starting light sleep using the below code, I am able to to go into light sleep and measure a current consumption of about 2mA, and when I exit light sleep and start advertising, I measure a peak consumption of about 16-20mA.

Code: [Select all] [Expand/Collapse]

1. case ESP_GAP_BLE_ADV_START_COMPLETE_EVT:
2.         //adv start complete event to indicate adv start successfully or failed
3.         if ((err = param->adv_start_cmpl.status) != ESP_BT_STATUS_SUCCESS) {
4.             ESP_LOGE(DEMO_TAG, "Adv start failed: %s", esp_err_to_name(err));
5.         }
6.         else {
7.             ESP_LOGI(DEMO_TAG, "woke up and now starting adv successfully");
8.         }
9.  
10.         int64_t t_before_us = esp_timer_get_time();
11.         vTaskDelay((1000*1) / portTICK_PERIOD_MS);
12.         int64_t t_after_us = esp_timer_get_time();
13.         printf("Returned from vTaskDelay, t=%lld ms, delayed for %lld ms\n",
14.                 t_after_us / 1000, (t_after_us - t_before_us) / 1000);
15.  
16.         esp_ble_gap_stop_advertising();
17.  
18.         break;
19.  
20.     case ESP_GAP_BLE_ADV_STOP_COMPLETE_EVT:
21.         if ((err = param->adv_stop_cmpl.status) != ESP_BT_STATUS_SUCCESS){
22.             ESP_LOGE(DEMO_TAG, "Adv stop failed: %s", esp_err_to_name(err));
23.         }
24.         else {
25.             ESP_LOGI(DEMO_TAG, "Stopped adv successfully and now going to sleep");
26.         }
27.  
28.         //below using light sleep
29.         esp_sleep_enable_timer_wakeup(4000000);
30.         /* Enter sleep mode */
31.         uart_tx_wait_idle(CONFIG_ESP_CONSOLE_UART_NUM);
32.  
33.  
34.         ESP_ERROR_CHECK(esp_light_sleep_start());
35.  
36.         esp_ble_gap_start_advertising(&ble_adv_params);
37.  
38.  
39.         break;

Is it okay for me continue using the above method, or do I have to use:

Code: [Select all] [Expand/Collapse]

1. ESP_ERROR_CHECK(esp_bluedroid_disable());
2.         ESP_ERROR_CHECK(esp_bluedroid_deinit());
3.         ESP_ERROR_CHECK(esp_bt_controller_disable());
4.         ESP_ERROR_CHECK(esp_bt_controller_deinit());

before going to light sleep and then

Code: [Select all] [Expand/Collapse]

1.           ESP_ERROR_CHECK(esp_bt_controller_init(&bt_cfg));
2.           ESP_ERROR_CHECK(esp_bt_controller_enable(ESP_BT_MODE_BLE));
3.           ESP_ERROR_CHECK(esp_bluedroid_init());
4.           ESP_ERROR_CHECK(esp_bluedroid_enable());
5.           ble_ibeacon_appRegister();

when waking up from light sleep. The problem with this 2nd method is that I measure a peak consumption of about 60-80mA when waking up from light sleep. I use a multimeter to measure current consumtion.
