CC2510: Communication between CC2500 & CC2510

Part Number: CC2510
Other Parts Discussed in Thread: CC2500, , TEST2

Hello,

I am currently using CC2500 with AT328P uC. I want to switch to CC2510 (SoC). I want to establish a communication between CC2500 & CC2510 so that my previous hardware is not wasted. I searched on this community about the possibility of communication between CC2500 & CC2510. It is possible as per one TI employee answer. As per his suggestion, I have made register settings for both the chip sets same but still I am not able to establish the communication.

Is there anything else I have to do other than register setting? What are the key registers?

Please help

Thanks

    Venu, 

    Can you post your register settings for both device and I will check them for you.

    Hi,

    Thanks for reply.

    Below are the register settings. I have used sample example TX & RX codes for CC2510 given by TI. I didn't fill the blank registers as they were not given in radio.h file. Do I have to add them?

    Venu, 

    I would recommend making the register setting identical between the two devices. They are both using the same radio core and also the same XTAL frequency. The only difference I saw, was the PKTLEN register that was not the same, this could be causing issues.

    Hi,

    I have programmed CC2510 as a transmitter & CC2500 as a receiver. In case of receiver does the PKTLEN register matters as we are sending PKTLEN information through transmitter ?

    Thanks

    When using variable packet length mode the PKTLEN register in RX sets the maximum allowed packet length. As an example, if the transmitted packet length is 20 bytes and PKTLEN on the RX side is set to 12 bytes the received packet is discarded.
