Looking at NuttX source code, I couldn't find any example of an
application that implements the ESP8266 functions. Is there any place
where I can find reference for this use?
There is a separate application in apps/netutils/esp8266. I've never
tried it though, so I don't now about its state.
There is also the the apps/wireless/gs2200m that is a very mature,
USRSOCK wireless interface and should be very similar to an ESP8266
USRSOCK solution.
The apps/netutils/esp8266 is a standalone C callable library for ESP8266
interfacing. It was contributed by Pierre-noel Bouteville in 2016 and I
am not aware that it has every been used since then.
I really should have a USRSOCK interface and should reside at
apps/wireless/esp8266.
