Are you using the Arduino platform for ESP32 development? If so, I think `delayMicroseconds()` is available.

Could you clarify what you mean by "...convert to ESP32 Modula"? Modula is a programming language developed in the 1970's. Do you mean to convert to ESP-IDF? If so, then install ESP-IDF per their instructions on the espressif.com site, and look at the basic examples to see how programs are structured.

They both support Wifi. Which one you choose depends upon your other detailed specifications: power consumption, how many and type of I/O ports, maybe cost, other features...

Also see the Espressif site discussion of this topic: Wi-Fi Provisioning. There are other options besides BLE. For example, you can use a configuration page implemented with Soft AP, or use Smartconfig.

That's 1000 lines of code you're asking people to review cold. Perhaps you can narrow the problem down somehow. What is the console output when the crash occurs? There's typically a lot of detail there that can point you to a more specific location of the failure (e.g., a specific function). You sho...

Great, thanks. Hadn't encountered that post after all the searching. The one I encountered said to include the policy setting to remove the warning.

Nobody knows how to get rid of this warning?

You mentioned it worked with the prior version of ESP-IDF then stopped working when you upgraded. Is the upgrade the only difference between the working version and the one that now doesn't work? Or are there app changes mixed in as well?

I haven't read the documentation to determine the limitations of it's capability, but I do know that OTA stands for "over the air".

I am getting the familiar warning from a fresh ESP-IDF build: CMake Warning (dev) at C:/Users/mdbra/Documents/esp-idf/components/mbedtls/CMakeLists.txt:114 (target_sources): Policy CMP0076 is not set: target_sources() command converts relative paths to absolute. Run "cmake --help-policy CMP0076" for...
