CCS/CC2650: EasyLink Tx and Rx

Tool/software: Code Composer Studio

Hello,

I am having questions related to the easylink Tx and Rx programs written by TI. I am using CC2650 LaunchPad. 

I downloaded the Tx and Rx programs into two CC2650 LaunchPads and the light on the board proves that the programs are working well.

I know that packets are transferred from Tx to Rx. I am wondering which part of the program should I modify so that certain data can be transferred from Tx to Rx? In my case, one of the ADC pins of the board is connected to an external analogue signal and I hope that the data from ADC can be transferred from this Tx to another CC2650 LaunchPad Rx. For the ADC part, I am using the ADC buf example written by TI and it is working well.

Should I incorporate the two programs? Are there any tutorials related to CC2650 easylink?

Besides, for this Tx and Rx program, are the data transferred using bluetooth? If so, how can I know?

I am a beginner in this field, sorry for so many basic questions, any replies will be much appreciated.

Thanks in advance!
