[ESP32-C3] RF calibration after wakeup from deep sleep

Postby glitch911 » Wed Sep 22, 2021 5:11 pm

Hello,

From documentation (https://docs.espressif.com/projects/esp ... alibration) RF calibration is not supposed to occur after wake-up from deep sleep as long as phy calibration data is available in NVS.

I use same code with former ESP32 and I can see on current measurement the RF calibration at power-up and no calibration after wakeup from deep sleep.

But with my new ESP32-C3 setup I still observe RF calibration (big current spike) :(

I'm I missing something or is this a bug ?

Thank you,

Thomas
