This is a slightly modified version of the BearSSL sample server for the ESP8266 Arduino framework using PlatformIO

Compile

first copy and edit the lib/private/PrivateConfig.hpp.sample file to lib/private/PrivateConfig.hpp

Notice

The code crashes if you run it on 80MHz CPU frequency, you have to switch to 160MHz to stabilize the program.

board_build.f_cpu = 160000000L in platformio.ini
