CCS/CC430F5137: Bidirectional Communication Issue

Part Number:CC430F5137

Tool/software: Code Composer Studio

Dear All,

I am using CC430F5137 for one of my project, in that while transmitter sends the data to a receiver then it will receive the data properly and i am getting the range up to 150mtr but in case of bidirectional communication i.e. transmitter sends the data to receiver and receiver acknowledge to transmitter in that type of communication I am getting range only 60-65 mtr. with same register settings.

So  kindly request you to give me a suggestions for this problem.

Thanks in advance.

Regards,

Avinash T.
