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: dfu-uti...

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: PS C:\Esp...

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-pytest ... ...

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: Extracting .../.espressif/dist/xtensa-esp-elf-13.2.0_20230928-x86_64-linux-gnu.tar.xz to .../.espressif/tools/xtensa-esp-elf/esp-13.2.0_20230928 Traceback (most recent call last): I'm on a Windows system, not Linux.

On my Windows 11 system, running inside ESP-IDF 5.2 CMD window, I'm trying to run install.sh as described in https://github.com/espressif/esp-idf/tree/master/tools/esp_prov#dependencies However, when I run it, it fails with "lzma module is not available": PS C:\Espressif\frameworks\esp-idf-v5.2.2> b...

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 https://github.com/espressif/esp-idf/tree/master/examples/provisioning/wifi_prov_mgr on an ESP32-C3. It compiles and runs without error. Now I would like to communicate with the wifi_prov_mgr app usin...

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 optimizi...

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 switc...
