Set up communication between CC2530 and CC2420

Other Parts Discussed in Thread: CC2420, CC2530

I am trying to use CC2530 demo board to receive data send from one CC2420 board which  is our released product. I used packet sniffer to analyze the data.

But I found that I can't found the data in Packet sniffer interface.

so I have following questions:

1.Does packet sniffer can read and analyze any type of data format based on 802.15.4? because our CC2420 device using our private protocol based on 802.15.4.

2.Is there any special setting in both two chip registers? 

3. what about the frequency difference tolerance if they can set up communication successfully? 300k HZ or smaller?

    Hi,

    CC2530 and CC2420 should be able to communicate with each other without any special setting as long as 802.15.4 layer is intact.

    I suggest you try using SmartRF studio to establish communication link between the two and evaluate RF performance. You can also shift the frequency to estimate xtal tolerance between the two.

    The sniffer should be able to decode 802.15.4 packets

    Oh, I found the reason. CC2420 can  configure the SFD to other value in addtion to 0xA7. As we know in 802.15.4 the SFD is 0xA7.

    so my question is:

    Is there any  other  wireless module like CC2420 which can configure the SFD value ?
