Serial Gateway.. Help!!

[SandeshHs94]

Guys,
I am completely new to mysensors and to date i feel this is the best approach, i dont understand a few basics, please answer to these questions.(I want to use serial gateway)

1)If i use arduino uno instead of mini/nano as given in sketch, should i be changing anything in the code given.

2)If i ad any new sensor should i add anything in gateway code for it to receive data or send data.

3)Can i add a sensor to gateway module itself.

4)If i choose to write a new code which is not in examples, how can i do it. is there any programming guide.

i would really appreciate if anyone can provide a complete guide link. I am sorry for such questions, i really need these answers.
Thank you

Hi @SandeshHs94, welcome to MySensors :-)

1. No changes are required for most examples
2. No changes to the gateway is required when adding more sensors (unless you use signing with white listing). The gateway only forwards data to your controller, it does not care about what sensors it forwards data for.
3. Yes, but only if you are running the development branch
4. The API documentation is available here: http://www.mysensors.org/download/sensor_api_15
