ROS Nodemcu Arduino compilation issue?

edit

Hey guys , i am trying to run this https://github.com/agnunez/espros

I got an error like this when i tried to compile ,

'class ArduinoHardware' has no member named 'setConnection'
 nh.getHardware()->setConnection(server, serverPort);
                 ^
exit status 1
'class ArduinoHardware' has no member named 'setConnection'

Any one faced similar problems before ?

I am trying to run this on Ros-Indigo (Might that be the problem , should i try some newer version)

https://www.youtube.com/watch?v=o_gFG... , this is what i am trying to do right now .

I can control the bot vai UDP packets generated from a python script .

But i would like to get it ROS enabled right from the MCU level . I know i can write a middle ware python script to make it ROS enabled .(but i want a cleaner code)
