@IMAN4K please rename ClientServer/client.ino to ClientServer/ClientServer.ino so Travis could proceed

Hi,

I think in examples one should use Library options and not direct SDK calls.

-> Ticker instead of os_timer_t

@hreintke
That's fine.
This is just an example with focus on TCP not the timing.
Anyone could pick whatever they prefer.
Anyway, you can commit after example get pushed to master.

@IMAN4K , please take a look at Travis job output

Seems like it tries to compile both ClientServer.ino and server.ino in the same pass. The reason, as I can see is the arduino sketch layout rules. .ino files are per-project, and should be the one and the only in the project directory and has the same name as the directory.

Could you please separate client and server examples to different folders?

Please note, if you have common configuration to both project (e.g. config.h) you should copy it to both folders too.

That's an odd thing! i was thinking for sketch as C++ source since they're using GCC as tool-chain for Arduino.
I'll modify it.

@IMAN4K, for sure. I'm suffering a lot from it too. But while you are compiling with GCC in Arduino, you should play the rules Arduino guys decided to use to manage includes and other stuff.

@IMAN4K sorry for the long delay! Thank you for those examples!
