LAUNCHXL-CC2650: Smart RF Sniffer Agent in SmartRF_Packet_Sniffer2_1.5.0 doesn't work

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2650

After install SmartRF_Packet_Sniffer2_1.5.0 on my Win7 PC, I find Smart RF Sniffer Agent in SmartRF_Packet_Sniffer2_1.5.0 doesn't work. It cannot detect my LAUNCHXL-CC2650 running sniffer_fw.hex under C:\Program Files (x86)\Texas Instruments\SmartRF Tools\SmartRF Packet Sniffer 2\sniffer_fw\bin\cc26x0lp. The Device Configuration is disable which means it doesn't detect CC2650.

I try to install previous SmartRF_Packet_Sniffer2_1.4.0 and it can work fine. Can TI tool team help to verify this?

Did you program the CC2650 launchpad with the new sniffer FW provided by the 1.5.0?

Yes, I do.

When programming the sniffer device with 1.5.0 FW, is the green LED blinking?

0 YiKai Chen over 6 years ago in reply to Severin Suveren

Guru 735535 points

Yes, it blinks slowly.

And if you connect a serial terminal to the UART port with 921600 baud, does it print out a string?

I see "TI Packet Sniffer ver.1.5.0". Do you test SmartRF_Packet_Sniffer2_1.5.0 by yourself on Win 7 and see it works?

0 Severin Suveren over 6 years ago in reply to YiKai Chen

TI__Mastermind 23730 points

Ok, so the FW looks OK. Could be something with the sniffer agent.

No, I don't have a win7 machine available. However, I've asked the Tools team to take a look at it.

I just test the same steps on another Win 10 PC and it works fine. I think this issue only happens on Win 7.

0 Severin Suveren over 6 years ago in reply to YiKai Chen

TI__Mastermind 23730 points

I'll report back when the Tools team has taken a look.

Thanks for your help and look forward to getting this issue fixed.

The Tools team tested this on windows 7, and it works. Could be that your windows 7 machine is not detecting the device or setting up the COM ports correctly. Have you tried clicking the "Search for New Devices" in Sniffer Agent?

0 YiKai Chen over 6 years ago in reply to Severin Suveren

Guru 735535 points

Yes, I test it many times. By the way, all other tools like Flash Programmer 2, SmartRF Studio, CCS are working fine.

Could you re-download the Packet Sniffer installer, uninstall currently installed version, and re-install. Could be that the installer is corrupted for some reason.

0 YiKai Chen over 6 years ago in reply to Severin Suveren

Guru 735535 points

I downloaded and test it yesterday. Does it make sense to download again?

0 Severin Suveren over 6 years ago in reply to YiKai Chen

TI__Mastermind 23730 points

I'm thinking more that the installer could be corrupted, but if you have downloaded it multiple times then it's probably not the problem.

Can you open up a terminal connection with the device, just as I asked in a previous post, and send the ping command to the device.

The ping command is the following raw bytes: 0x40, 0x53, 0x40, 0x00, 0x00, 0x40, 0x40, 0x45

You will see the device responding.

I have left office and won’t be able to access my desktop during the weekend. Will test this next week and let you know.

Ok. It sounds like something is blocking the serial port on the device. We've verified locally the Sniffer Agent works as intended on windows 7, and the device firmware seems to be working as expected as well. To me it sounds like something on the machine is blocking/claiming the serial port, which makes the Sniffer Agent unable to communicate with the sniffer device.

Guru 735535 points

If there’s something on the machine is blocking/claiming the serial port, which makes the Sniffer Agent unable to communicate with the sniffer device, why I install previous version without reboot and it works immediately?

0 Severin Suveren over 6 years ago in reply to YiKai Chen

TI__Mastermind 23730 points

That's what confuses me.

Could you try when you are back in office to re-install Sniffer 1.5.0, restart the machine (just to make sure the serial port is free) and try again.

0 YiKai Chen over 6 years ago in reply to Severin Suveren

Guru 735535 points

I had tried that too. Anyway, I will test it again next Monday.

Hi,

a colleague asked me to take a look because I am running on Windows 7 (64 bit). I have never installed Packet Sniffer before. After installation and flashing the firmware, everything worked. Then began to play around with the program to see how I can break it and was able to reproduce a scenario that you describe:

I set another baudrate than the preconfigured 921600 in "Options" -> "Serial Port Settings"
After that, the sniffer was not able to connect any more
This option is persistent and even survives re-installation of Packet Sniffer. That's wrong behavior IMO. Settings should be removed during uninstallation.

Therefore I guess you have (by accident) misconfigured some settings. Please try:

Delete the sniffer settings file C:\Users\<USER>\AppData\Local\Texas_Instruments_Inc\sniffer_agent.exe_Url_5swzk5sey2l4w3ssee14grt1t5lr5vb0\1.5.0.0\user.config
Start Packet Sniffer. It should now run on default settings and create a fresh file.

I hope this solves the problem.

Richard W. After checking my C:\Users\\AppData\Local\Texas_Instruments_Inc\sniffer_agent.exe_Url_5swzk5sey2l4w3ssee14grt1t5lr5vb0\1.5.0.0\user.config, the baudrate is changed to 115200 but I don't remember I do that. Anyway, sniffer_agent 1.05.00 works now after I change the baudrate back to 921600. Thanks for you help.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
