created two versions of wifi-controller.c: one using API version 4.0 and one using API version 4.1.
4.1 is identical to wifi-controller.c and used for "latest" esp-idf.
4.0 is used for PlatformIO, as PlatformIOuses esp-idf 4.0.1

Please compare this files contents with espidf-v4.1.c, and confirm that there are no unintentional changes.
Intention was to build a version for API version 4.0.

Used to turn on HKDF in esp-idf 4.0 contained mbedTLS.
This is included at the end of mbedtls/esp_config.h via
-DMBEDTLS_USER_CONFIG_FILE=\"mbedtls+HKDF.h\"
. See platformio.ini .

platformio default source directory is "src". This is used to adjust to esp-idf preference of "main".

CMakeLists.txt are parsed differently than in esp-idf. This is compensated here.
-Iinclude -DMBEDTLS_USER_CONFIG_FILE="mbedtls+HKDF.h"
is used to enable HKDF.
board_build.embed_files is PlatformIOs way for including verbatim file contents into build result.

does not work yet, and probably will be hard to implement. This platform is a 15EUR nRF51822 based over-the-air-flashable fitness tracker bracelet.
Just 32kBytes of RAM and 256kBytes of flash. Might be enough for a "tracking only" device for a few days, with off-loading to and risk calculation on smartphone.

merged into new branch 'zephyr' |
CovidBracelet was moved to platformio.
PlatformIO is a framework that supports a lot of embedded development platforms, inluding esp-idf as well as zephyr.
One drawback is that PlaformIO is using esp-idf v4.0.1 instead of v4.1. That is why I had to downgrade wifi.c to esp-idf v4.0 API. I am not sure if my implementation is correct - cannot test because I do not yet have a suitable board.
I implemented this switch by converting wifi.c into a directory with various implementations - in this case two different esp-idf versions. I intend to do the same for bluetooth support for esp-idf vs. zephyr.
