NimBLE start-up time after deep sleep

[timmbo]

Hi all,

my system currently wakes up every 60 seconds to advertise and receive beacons for 1100ms. Then it goes into deep sleep again.

After waking up I always call the method

esp_nimble_hci_and_controller_init();

which takes around 500ms while consuming an average of 100mA (running @80MHz), which is quite a lot of energy!

Do I always need to execute the method after coming out of deep sleep? Is there any way to shorten this or reduce the power consumption during the 500ms (e.g. by clocking down to 10MHz?).

Thanks in advance & Greetings,
Timm
