Re: SMALL_TEST in FreeRTOSConfig.h

We'd advise not to mess in the freertos config as some other components are dependent on certain things set to certain values. With that being said: Is there a reason you need to change this?

Re: Rf based positioning using phase differences

Hold that thought: something has been recently merged. Does https://esp-idf.readthedocs.io/en/latest/api-guides/wifi.html#wi-fi-channel-state-information do what you want?

Re: .Net Micro Framework on ESP32 chip

Someone at Espressif is writing an LLVM backend for the Xtensa right now. I'd wait for that. Oh wow, that is amazing! Where did you hear this? I can't seem to find it. Not sure where he heard it, but it's true. We'll probably release an ESP8266 version first, as that architecture is a bit simpler (...

Re: Rf based positioning using phase differences

I think the hardware actually should have support for this (with a few restrictions, as in, if I recall correctly it only works for certain encodings), however the drivers do not have functionality to output the associated data yet. Also, the functionality is mostly untested so we don't know if it w...

Re: TX Power Consumption with Impedance Mismatch

That would indeed be a good feature to have. I'll ask around to see if we can implement this. Edit: Analog people tell me they are working on this and have a possible way to do this (both the no-antenna-detection as well as the power draw when no antenna is connected) but they need to run tests to s...

Re: ADC1 on Adafruit Feather HUZZAH-ESP32 doesn't work with esp-idf

Because the output displayed different values with open inputs, I connected alternately the input pins with GND. Running this code displays that the unit ADC2 only works. What do you mean by this? Have you tried the obvious as well, that is, feeding a known, perhaps varying voltage into the ADC pin...

Re: internal functions source code

What do you mean? If you mean general TLS etc, that is open-source (see the mbedtls component). If you mean the AES encryption that's going on in WPA/WPA2/..., I think that's done in hardware. The setup for this is done in wpa_supplicant, however, and that should be open-source in the latest master.

Re: How to force a CPU reset?

No, not at all. It essentially just resets a bunch of flipflops to a default state, when looking at the chip level. You can theoretically have some higher-level effects, for instance when you reset the CPU in the middle of a flash write when the software cannot handle interrupted flash writes correc...

Re: ESP32 Github Core-- Is this a joke

To be fair there, the way Arduino support is implemented for the ESP32 makes it pretty easy to migrate to the 'full' ESP-IDF environment if you so please: the entirety of ESP-IDF is callable from the Arduino side and it's possible to import the Arduino component into esp-idf and essentially make an ...

Re: internal functions source code

No, sorry. While we're actively working on opening code from our WiFi driver, the functions in this file aren't open at this moment. Can I ask what reason you have to need this source code?
