Today I tried to use an ESP8266 smartconfig example. However I failed to build it with message below:
src/smartconfig_main.c:12:35: fatal error: freertos/event_groups.h: No such file or directory
It is turned out that PIO download platform RTOS_SDK with version 1.5.0-beta.5. However, it seems there are newer version of the SDK which I need. How can I change the configure and use correct framework version?
This is the example I would like to run with PIO: https://github.com/espressif/ESP8266_RTOS_SDK/tree/master/examples/wifi/smart_config
Thanks for your help.
