https://docs.espressif.com/projects/esp-iot-solution/en/latest/usb/usb_overview/usb_vid_pid.html in documentation it is mentioned that if You use TinyUSB stack you do not need to get a PID if you wan't to produce a product but don't need to stand out. I was wondering how is it with the USB Serial ...

For some reason when I bump up sampling freq to >10kHz and run esp_wifi_start() the adc_continuous_read() function starts timing out. Is it perhaps due to the reason that WiFi controller polls the ADC for values and in turn blocks the SAR ADC ?

I was wondering if it's possible to get PWDET controller data, this way I would be able to measure the energy that's coming to the antenna.

Use the ESP-IDF adc_cali_* APIs (ADC calibration driver).

Capture a new baseline once Wi-Fi is active, and subtract that from your continuous readings.

Yes, that is one way to fix the issue. Doesn't tell us why this happens though! The root cause is what's interesting.

I'm dealing with a problem that when I run esp_wifi_start() I get an ADC continuous reading drop of ~30 raw ticks. I'm using esp32c6 devkit m1 ADC_UNIT_1, atten_12.
This problem persists even when I flash code with that line commented out. Only when power is cycled with commented code does it ...

Are you facing the same issue with the ESP32-S2, @ginspe?

I see another topic created by you here.

No it's with C6. Saw this topic was quite old so I thought I'd start a new one. But the issue still stands.

Hello everyone!
Why is there a check on adc_continuous_config() (IDF v5.5) on whether the attenuations match per unit? Page 1360 of technical reference manual even shows an example of this. Is this due to the calibration driver problems that would arise when doing so?

Please fix this issue.

I was wondering how does esp-now protocol handle overcrowded channels? Can two ESP devices change channels automatically?
