Re: Low Rate WIFI Protocol LR

@Rudi: my long range test didn't go well because of a mechanical problem on the test vehicle (motor support plate fell apart). Will try again when I figure out how to 3d print a new one...

Re: proposal: forwarder service for links

It's pretty simple: don't post links to tree/master, point to the exact commit ID or tag: https://github.com/espressif/esp-idf/tree/0bbc60618bcd1cbe44c546f0c4e38a83f0597ad2/examples/protocols/mdns (FWIW, we have the same problem with our readthedocs documentation, which needs to be addressed, but in...

Re: ULP for SPI sensors

Okay, we'll push the toolchain over to Github.

Regarding timeline for full integration into the build system, it should be ready by the end of next week.

Re: ULP for SPI sensors

Initial binutils version for the ULP has been finished, although code generation hasn't been tested extensively yet. We are working on integrating the ULP toolchain into the build system, so that you can access variables declared on the ULP side from the Xtensa core directly by their names, and load...

Re: Proper way to init phy_init and NVS?

Select "Use a partition to store PHY init data" in menuconfig, then run make phy_init_data Output file will be in build/phy_init_data.bin. To flash just this file, run make phy_init_data-flash This file is also generated if you just run "make", and is flashed to the ESP32 if you ...

Re: ESP32 and CR2032 battery

Shouldn't it be possible to skip all RF calibration at the possible consequence of reduce RF performance (assuming there is stored cal data)? PHY init can be performed by the application itself — just uncheck CONFIG_ESP32_PHY_AUTO_INIT option ("Component config" -> "WiFi" -> &qu...

Re: chip_id for ESP32

MAC address can be changed once by programming a customer-defined address into efuses. If you want to make sure that device users can not change MAC address, you need to write-protect these efuses (check the technical reference manual and espefuse.py tool help for details).

Re: ESP32 Suitability for Project?

Regardless of the development environment, you need to use https://github.com/espressif/esp-idf as the development framework. On Windows, you can use Eclipse or Visual Studio with VisualGDB plugin (https://visualgdb.com/w/tutorials/tag/esp32/). One note about VisualGDB though: it is not clear how of...

Re: chip_id for ESP32

Regarding the chip ID, it is basically the chip's MAC address, which can be obtained using esp_efuse_read_mac function.

As for reading the flash chip ID, we don't have this in the ESP-IDF yet. I'll put your feature request on our list.
