Other Parts Discussed in Thread: CC430F6137

Hi everyone,

 

I try to use Packet Sniffer to capture packets between a pair of eZ430 Chrono Watch and Access Point. But I captured some strange packets instead.

Here is how I did it, please advise if anything might be wrong.

1) I programmed a CC1111 usb dongle as a Packet Sniffer use the firmware image<sniffer_fw_ccxx11.hex> use SmartRF Flash Programmer

2) I power up and configured eZ430 Chrono Watch and AP to transmit under the ACC mode, so that I can see the real time acceleration data sent from the watch use Control Center.

 

Problem:

I Can't see the packets that contains Acceleration data/Application payloads, Instead, the packet sniffer captures 1 packet every 3~9 mins. All captured packet has a FCS error

 

Please help and advise on this.

    Hi all,

    I have been told that the Register Configurations of the Watch or AP is what I should export from the SmartRF studio. So I did and tried following:

    1. Open Watch's (CC430f6137) Register Setting use SmartRF Studio 7.

    2. Save the Register Setting in .prs format.

     

    But When I open the packet sniffer GUI with CCDebugger and CC1111 dongle plugged in a laptop, and loaded this .prs file, then start > the capturing, it still don't show any packets.

     

    Is it somewhere in the process I have done it wrong?

     

    Please advise on the correct operation procedure.

     Thanks
