sleep mode current high (3mA) after enabling and disabling BLE, if not < 1 mA

Postby vinodstanur » Tue Mar 31, 2020 4:23 pm

Hello,

I am able to achieve sleep mode current < 1 mA if my BLE is not enabled for first time.

Code: Select all

	esp_sleep_enable_gpio_wakeup();
	esp_light_sleep_start();

Now with gpio if I enable BLE and then disable it by below commands and then if I do above sleep commands,
it is going to sleep but taking around 3+ mA of current. I am unable to bring it down.

Code: Select all

	
		esp_bluedroid_disable();
		esp_bluedroid_deinit();
		esp_bt_controller_disable();
		esp_bt_controller_deinit();	
I am using above commands to disable BLE completely and no user task is running and all tasks are blocked using a SLEEP_EVENT before issuing the esp_light_sleep_start.

Issue can be solved only if I reboot the esp32 and if ble is not enabled for first time and if I sleep the device, it takes <1 mA. At any time if I use ble and later disable also, then the sleep mode current is increased to 3+ mA and I am unable to reduce it :(
