CC1110-CC1111: How to set up the CC1110 dongle to capture RF packets from CC430

Part Number: CC1110-CC1111
Other Parts Discussed in Thread: CC430F5137, SIMPLICITI

Hi TI team,

Last week, I bought a CC1110 dongle in order to capture RF packets from CC430(cc430f5137).

The device based on CC430 is other company's one so I don't know what frequency is being used and how the RF register's are set up.

However, I have tried to capture RF packets from CC430, but I couldn't see any packet from TI SmartRF Packet Sniffer.

(Both Generic, SimpliciTI mode)

How can I capture RF packets from CC430 using CC1110?

Please let me know the right approach. 

Thank you.

    You need a spectrum analyzer. First, you have to find the frequency the device sends on. Then you have to determine the modulation format.

    Then you can use SmartRF Studio, setting the device in async mode and use a scope to find the datarate. Then you can set the device in packet RX and use 0xAAAA as sync word to find the sync word etc.

    In short you need to know a fair amount of what the device sends before you can sniff packets.

    Dear TER,

    First of all, thank you for  your reply and I appreciate it.

    In addition, here are some questions about your reply.

    1. Regarding the frequency

        : As fa as I know, there are three types of the frequency(430, 868,902MHz) in CC430

        : Should I find the exact center frequency among them?

    2. Regarding SmartRF Studio

        : Why should I use Smart RF Studio to capture RF packets?

        : And also the SmartRF Studio 7 which I am using does not find the CC1110 usb dongle device at my Windows PC? 

    Should I use the SmartRF Studio not TI Packet Sniffer for that?

    Thank you.

    1) It's a bit more complicated. 868 MHz is basically a frequency band meaning 863 MHz to 870 Mhz and you can typically select ant frequency between the min/ max. This goes for the other bands also.

    To be able to sniff a packet you need to know some basic things and that you have to find with other tools than the packet sniffer.

    Not sure why your sniffer is not visible on your PC. Has the driver been installed properly?

    Dear TER,

     

    Q) To be able to sniff a packet you need to know some basic things and that you have to find with other tools than the packet sniffer. 

    Answer) I see. I'll find other things for that.

    Q) Not sure why your sniffer is not visible on your PC. Has the driver been installed properly?

    Answer)   It is connected just via USB port of my PC. TI Packet Sniffer tool can find the device correctly.

                     However SmartRF Studio 7 tool can't find the device.

                     I think that SmartRF needs other communication path.(ex. xds?) Am I correct?

    Thank you.

    From www.ti.com/.../swru328.pdf:
    "For An external development board or
    debugger, like the CC Debugger,
    SmartRF04EB or SmartRF05EB, is
    required to program and debug
    software running on the CC1111."

    This also applies for SmartRF Studio.
