sniffer 2.18.1

Other Parts Discussed in Thread: CC2531, CC2500, CC2511

Hi all,

I am trying to use packet sniffer based on the cc2531, using sniffer 2.18.1.
protocol type - generic. we send packets on 2.480 Ghz, baud 250K, 12 bytes data, ID=0, 2 bytes sync, 4 bytes preamble
we do not see anything on screen.

the sniffer recognizes the dongle, but does not open the tabs that enables parameters setup, such as baud rate.
how can I setup the comm parameters, such as baudrate, and others?
maybe another version, older version works?
thanks

Israel

  • Hi Isreal,

    Could you share what the view is in your case? What methodology did you use exactly when setting this up? Did you flash the sniffer FW to the dongle?

  • Hi,

    Thanks for the reply.
    I loaded the sniffer with sniffer_fw_cc2531.hex using the cc debugger.
    then I open the app, getting the first window where I choose "generic"
    then the left window is opened, it recognizes the cc2531, and I have a parameter of channel to choose.
    according to the swru187g.pdf some other configuration options should be opened.
    thanks for the help.

  • Hi Israel,

    I'm afraid your image link seems to be broken, you could try to upload the image again.

    Unfortunately I can't test this out myself as I do not have a device available right now but I seem to remember options being related to what protocol you are opening the device in. The user's Guide show an example on how it would look when the IEEE802.15.4/ZigBee is selected.

  • Hi M-W,

    the image was about a screen shoot of the sniffer app.

    never mind that.

    we are using the cc2500 in our own protocol.

    choosing 2480 Mhz channel, and variable baud-rate from 250K to 9600.

    the point is, when using "generic" option in the app, no tab is opened where I can setup the baud rate. 

    you can open the app and try it yourself. 

    do you have any other dongle than cc2531 to try it?

    maybe it works with another dongle? 

    thanks

  • Hi Israel,

    Unfortunately I do not have access to any similar dongles (due to the current Corona situation, I'm no were close to my office). I will see if I can find a colleague with a dongle that could possibly look at it. 

  • As you are using CC2500, I would assume you need to use the CC2511 dongle in order actually capture anything. The CC2531 is an IEEE/Zigbee radio, I'm not sure it could actually receive the CC2500 as this does not support the IEEE PHY.

    While the CC2531 is order under "proprietary" on the Packet Sniffer download page, this only means it support "proprietary IEEE" and not all proprietary protocols. You can see in the right most columns which device can be used to capture packets from another device. As you can see, CC2531 can not capture CC2500 packets.

  • Hi M-W,

    Thank you very much for the reply.

    this dongle CC2531 was recommended by the TI local distributor.

    I will try to see if we can buy another dongle.

    any chance TI can replace us the non fit dongle?

    best regards

  • Hi Isreal,

    I would assume this was a mistake from their side if that is the case. If you refer to the table on: http://www.ti.com/tool/PACKET-SNIFFER, you will find that the CC2531 can not be used to capture data from the CC2500 (the two last columns in the table gives sniffer device vs capture device). 

    Based on you, it sound like you bought it not from TI directly but from a third party distributor? If that is the case, I would recommend to first contact them for a possible replacement/return as you acted on their recommendation. The official TI policy is that if you buy via the authorized TI distributors, then you need to follow their process for any return procedures.
