Problem In communication Between CC1101 and CC430F6137 (EZ430-Chronos)

Other Parts Discussed in Thread: CC1101, CC430F6137

When I used two CC1101 module then there is good communication between both module. But when I used one CC1101 as receiver and one CC430F6137 (EZ430-Chronos developement board) as transmitter, I am not getting anything in CC1101 module. But CC430F6137 is transmitting some data. I checked this using Spectrum Analyzer. I also keep the RF_Setting Configuration same in both module. Can someone please tell me what may be the possible cause. What precaution should be taken while communication one CC1101 and one CC430F6137 module.

Thanks

No special precautions are required to communicate between a CC1101 and a CC430 since the radio part is equal.

- Have you verified that the two modules operate on the same frequency?

- Do you see the RSSI on CC1101 increase when you send data from CC430?

I put the same configuration for RF_ Setting using the Smart Rf Studio. But I am not getting any data in CC1101 when I am transmitting from CC430. If possible then can you provide me some demo code for testing. Because I am not getting any data using CC1101. Is there any thing like we should have same RF circuit for both CC1101 and CC430.

Thanks

We have no demo code for these two chips together. To be able to help you please see me questions from my previous post.

How to ensure that both are working in same frequency.

You set both boards in TX sending a CW and use a spectrum to check the frequency they send on.

Ok.. thanks.. I will try this and let you know.

Hi.. I checked this using spectrum analyzer. It is working in same frequency but CC1101 is not receiving data. Even when I used Ez430-chronos (CC430F6137) development board as a transmitter and one CC430F6137 as a receiver I am not getting anything in receiver module. But when I checked receiver module antenna using spectrum analyzer, it is receiving some data but microcontroller in CC430F6137 can't detect this. Using spectrum analyzer I ensured that transmitter is transmitting some data. So can you suggest me what to do next. Thanks And Regard Vivek
