Thanks. Boo.

Is there any document from Espressif anywhere that spells out which parts are open & which are closed source?

Where can I find the source code for this function: esp_wifi_scan_start().

Is it available?

The esp-idf repository has header files and examples only.

I know this is an old query, but I just ran into it.

Found an answer here: https://github.com/espressif/esp-idf/issues/4369

(...but still can't get my Android device to use mDNS unfortunately.)

I've looked all over for a "Read the Docs" style online API reference (or similar) covering these libraries: https://github.com/espressif/arduino-esp32/tree/master/libraries I know that some of it is covered in the Arduino reference, as mentioned here: https://docs.espressif.com/projects/arduino-esp...

Yes, I know I could do that, but that doesn't explain why the bootloader.bin ends up larger by about 2K... Makes me wonder what _else_ is different. Maybe nothing...

I've successfully compiled and run the camera_web_server example using esp-idf 3.3.1 and the default toolchain. But, on Windows, building under the MSYS32 environment is painfully slow. I'd prefer to use the Cmake preview. Since the example projects include CMakelists.txt files, I assumed this would...

Here's my source code (including a log as produced by 'make monitor').
The 'stepper_test' directory goes in 'examples' under esp-iot-solution/.
I'm also including my modified a4988 directory. The only change is the two lines mentioned above.

Thanks for taking the time!

Will do shortly. I got tied up for a few days. Thanks for your interest.

I want to drive stepper motors, so I'm trying out the a4988 component. No luck so far. With code straight from the repo, I get this: . . E (247) ledc: ledc_set_duty_with_hpoint(383): hpoint argument is invalid . . Looking at the a4988.cpp(), it appears that the ledc init code never set this 'hpoint'...
