Using 3DR Radio telemetry with navio2

how to use 3dr radio telemetry with navio2?

Hi,

it is all covered in the docs:
http://docs.emlid.com/navio2/Navio-APM/hardware-setup/

I am going to write my own code. I am not using APM code. So can you help me?

Hardware connection is the same no matter what code you use.
3dr radios are just a serial connection. How to access serial ports depends on what language you are going to use.

Thank you. I wrote small C++ code for serial communication. Now it works fine.
