I just performed a fresh install of ESP IDF 5.2 with the offline installer ("Espressif-IDE 3.0.0 with ESP-IDF v5.2.2" for Windows 11. I used the default options for installation.

The installation completes without error. But launching the ESP-IDF cmd window fails, putting up an alert window:

I want to compile a version of
Espressif\frameworks\esp-idf-v5.2.2\examples\provisioning\wifi_prov_mgr
to use security version 0.

Short form:
What must I change in menuconfig to specify security level 0?

Details:
Running ESP-IDF 5.2 (under Windows 11) with an ESP32-c3, I launch menuconfig ...

Solved.

Although the https://github.com/espressif/esp-idf/tree/master/tools/esp_prov#dependencies states:

This requires the following python libraries to run:
bleak
protobuf
cryptography
To install the dependency packages needed, please run the following command:
bash install.sh --enable ...

Solved.

Though the document
https://github.com/espressif/esp-idf/tr ... pendencies
doesn't specify say so, on a Windows system you need to run
.\install.bat
rather than
bash install.sh --enable-pytest

Using .\install.bat the script completed without error.

Addendum:

This line in the script is suspicious:

On my Windows 11 system, running inside ESP-IDF 5.2 CMD window, I'm trying to run install.sh as described in

However, when I run it, it fails with "lzma module is not available":

Update: I realized that I had not run Those commands completed without error, but after doing so, I still get "No module named 'google'" as described in the original post.

Using a fresh build of the ESP IDF 5.2 shell under Windows 11, I have built and flashed the code in

on an ESP32-C3. It compiles and runs without error.

The more things that can wake the processor from sleep, the better.

One that I've not seen anywhere is a "sleepy UART" mode that draws almost no current until a start bit is seen, then proceeds to capture the entire first byte as it wakes the processor.

If you want a longer discussion about ...

Are you are saying that FreeRTOS is permanently baked into every ESP32 application?

That would be a pity -- as good as FreeRTOS is, the mulib framework I'd like to port is extremely efficient for low-power applications -- it's inherently tick-less and its single threaded design means that task ...
