Why do you have to disable BLE before going to light sleep mode ESP-WROOM-32D?

[leogs01]

Code: Select all

 case ESP_GAP_BLE_ADV_START_COMPLETE_EVT:
        //adv start complete event to indicate adv start successfully or failed
        if ((err = param->adv_start_cmpl.status) != ESP_BT_STATUS_SUCCESS) {
            ESP_LOGE(DEMO_TAG, "Adv start failed: %s", esp_err_to_name(err));
        }
        else {
            ESP_LOGI(DEMO_TAG, "woke up and now starting adv successfully");
        }

        int64_t t_before_us = esp_timer_get_time();
        vTaskDelay((1000*1) / portTICK_PERIOD_MS);
        int64_t t_after_us = esp_timer_get_time();
        printf("Returned from vTaskDelay, t=%lld ms, delayed for %lld ms\n",
        		t_after_us / 1000, (t_after_us - t_before_us) / 1000);

        esp_ble_gap_stop_advertising();

        break;

    case ESP_GAP_BLE_ADV_STOP_COMPLETE_EVT:
        if ((err = param->adv_stop_cmpl.status) != ESP_BT_STATUS_SUCCESS){
            ESP_LOGE(DEMO_TAG, "Adv stop failed: %s", esp_err_to_name(err));
        }
        else {
            ESP_LOGI(DEMO_TAG, "Stopped adv successfully and now going to sleep");
        }

        //below using light sleep
		esp_sleep_enable_timer_wakeup(4000000);
		/* Enter sleep mode */
		uart_tx_wait_idle(CONFIG_ESP_CONSOLE_UART_NUM);


		ESP_ERROR_CHECK(esp_light_sleep_start());

		esp_ble_gap_start_advertising(&ble_adv_params);


        break;

When starting light sleep using the above 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. Is it okay for me continue using the above method, or do I have to use

Code: Select all

ESP_ERROR_CHECK(esp_bluedroid_disable());
		ESP_ERROR_CHECK(esp_bluedroid_deinit());
		ESP_ERROR_CHECK(esp_bt_controller_disable());
		ESP_ERROR_CHECK(esp_bt_controller_deinit());

before going to light sleep and then

Code: Select all

		  ESP_ERROR_CHECK(esp_bt_controller_init(&bt_cfg));
		  ESP_ERROR_CHECK(esp_bt_controller_enable(ESP_BT_MODE_BLE));
		  ESP_ERROR_CHECK(esp_bluedroid_init());
		  ESP_ERROR_CHECK(esp_bluedroid_enable());
		  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.
