Sniffer for nRF52 DK

I downloaded this package but I'm missing a readme / instructions on how to use it.

Step 1 probably flashing "sniffer_pca10040_51296aa.hex" on my PCA10040 Dev board.
Already have installed Jlink software for use with the Segger Embedded Studio, but how do I now make my wireshark read and display packages from the NRF52832 board?

UPDATE: okey so I found this nrf_sniffer python script and tried running it, but even though the python-serial package installed on my system is 3.0.1-1 it fails with this error:

nrf_sniffer_2.0.0-beta-1_51296aa/extcap $ ./nrf_sniffer.py --extcap-interfaces
extcap {version=2.0.0}{display=nRF Sniffer}{help=http://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Sniffer#Downloads}

  File "./nrf_sniffer.py", line 123, in get_interfaces
    raise RuntimeError("Too old version of python 'serial' Library. Version 3 required.")
RuntimeError: Too old version of python 'serial' Library. Version 3 required.

UPDATE2: I found a userguide! https://www.nordicsemi.com/eng/nordic/Products/nRF52-DK/nRF-Sniffer-UG-v2/65245

Will read that now.

UPDATE3: was able to resolve the issue with python-serial by uninstalling the package python-serial v3.0.1-1 from my distribution and installing pyserial 3.4 using this command:

python -m pip install pyserial

The nRF Sniffer v2 beta 1 is now available for nRF52-DK.

When i run the sniffer, it crashed and give the following log.

12:59:49 (China Standard Time) ERROR: Traceback (most recent call last): File "C:\bamboo\xml-data\build-dir\BLESNIFFER-RELEASEBUILD-JOB1\Host\Application\SnifferAPI\Packet.py", line 160, in getPacket File "C:\bamboo\xml-data\build-dir\BLESNIFFER-RELEASEBUILD-JOB1\Host\Application\SnifferAPI\Packet.py", line 137, in decodeFromSLIP UARTPacketError: Unexpected character after SLIP_ESC: 124. 04-Oct-2017 12:59:49 (China Standard Time) ERROR: CRASH Traceback (most recent call last): File "C:\bamboo\xml-data\build-dir\BLESNIFFER-RELEASEBUILD-JOB1\Host\Application\SnifferAPI\Sniffer.py", line 150, in run File "C:\bamboo\xml-data\build-dir\BLESNIFFER-RELEASEBUILD-JOB1\Host\Application\SnifferAPI\Sniffer.py", line 175, in runSniffer File "C:\bamboo\xml-data\build-dir\BLESNIFFER-RELEASEBUILD-JOB1\Host\Application\SnifferAPI\SnifferCollector.py", line 153, in _continuouslyPipe AttributeError: 'NoneType' object has no attribute 'valid'

any clues?

Is there an official nRF sniffer released for nRF52840?

I'm just going to include all the stuff I used to get this working:

nRFgo Studio: www.nordicsemi.com/.../nRFgo-Studio
nRF command line tools - this might be your problem. I couldnt get setup working with the package that came bundled with nRFgo Studio, so I uinstalled the version that came with nRFgo studio (via computer -> Uninstall programs) and downloaded the latest v9.3.1 from here and installed with defaults: www.nordicsemi.com/.../33444
The hex file I used was the one from directly below this post posted by Hung Bui: Unofficial_nRF_Sniffer_4_nRF52DK.hex
nRF Sniffer.exe: www.nordicsemi.com/.../
Wireshark v1.10.14: www.wireshark.org/.../

Let me know if that does/doesnt work. I wrote down a bunch of notes as I was troubleshooting.

@lbehhhh. When I type 'w' the wireshark does start up. But, doesn't show any packets. However, I could see atleast the initial advertising packets before starting the wireshark. I will try with v1.10.14. Also, can you please let me know which particular hex file you used for testing. Because, there are multiple hex files on this forum, which works for some and doesn't for some others. So, I would prefer having the same hex file as yours.

@kirchki When you type 'w' into the sniffer console does wire shark actually start up? Does it give you an error? I tried with latest version of wireshark and was unsuccessful. I installed v1.10.14 and got it to work. I am using nRF52840 DK and can capture packets. Also make sure you are running the Sniffer.exe as admin

Hello, I flashed the hex on the nRF52DK and start the ble-sniffer_win_1.0.1_1111_Sniffer.exe. The sniffer finds the BLE devices. After this i select a device to sniff the packets on it. But it says firmware outdated. From the other posts, i understand that this message can be ignored(?) since the hex is not official. But, once i select a device to sniff and type 'w' to start the wireshark, i dont see any packets captured by the wireshark. I tried with setting a filter of Tx power <= 4dB, because the advertisements are being Txed at 4dBm. Can anybody tell me what I am missing

I know which settings I'm using, how do someone edit the hex to change the pins? Unless I've totally missed the source the of the sniffer being available.

RE: Sniffer for nRF52 DK

Susheel Nuguru — Fri, 25 Nov 2016 09:10:43 GMT

you have to look into boards.h file and see which board settings you are using.

How does one remap the UART pins? I'm trying to load the Sniffer on an OSHChip (nRF51822) that doesn't have pins 9/11 exposed.

I have a NRF52 dev kit and trying to get this board to work as a sniffer. Downloaded above firmware Unofficial_nRF_Sniffer_4_nRF52DK.hex and using python sniffer example. but it is not detecting any ble devices. Do i need to download another firmware?

Did a quick test on two laptops.

Laptop A with nRF51 Dongle, official sniffer firmware, wireshark v1.12.7

Laptop B with nRF52DK, this hex file, wireshark v2.0.3

Laptop A is showing SCAN_REQ/SCAN_RSP no problem.

Laptop B is only showing SCAN_REQ, no SCAN_RSP is captured.

I didn't try more configurations to see where is the problem. I am afraid of breaking my working environment.

I thought just reporting what I saw.

No luck here... Installed Segger 5.10u force a firmware update (meaning that it wasn't detecting a old one) and still got the same message.

RE: Sniffer for nRF52 DK

KingKarl237 — Wed, 30 Mar 2016 14:28:23 GMT

Solved it by myself. Updated Segger, restarted, worked.

RE: Sniffer for nRF52 DK

Diogo — Wed, 30 Mar 2016 11:38:03 GMT

Also the firmware outdated continues to appear... My guess that the CTRL-R programming fails is that the application is passing the wrong family in the programming line... But even then, how does it detect an outdated version, shouldn't this unofficial release be an higher revision version? Also which firmware is it complaining about? nRF or JLink?

RE: Sniffer for nRF52 DK

KingKarl237 — Wed, 30 Mar 2016 11:25:40 GMT

Same problem with this firmware. Just showing Advertisement-Packets.

RE: Sniffer for nRF52 DK

Thanks, Hung will try that.

Hi,

I attached here a new hex file for the sniffer for nRF52 DK. Please be aware that this is unofficial, and not fully tested. A small bug fix for this bug also added.

You will see the sniffer console complains about firmware outdated, please ignore that.

Unofficial_nRF_Sniffer_4_nRF52DK.hex

RE: Sniffer for nRF52 DK

Susheel Nuguru — Wed, 30 Mar 2016 10:19:53 GMT

Hi Diago,

The reason that you are not able to program is because the internal scripts of sniffer became outdated as nrfjprog latest version made removed '--programs' and does not allow mixing commands anymore. So it is best to program the sniffer using nRFGo or explicitly by nrfjprog. It should not be a program and seems like you managed to do it. My Colleague @hungbui will update this thread soon with latest unofficial version with few fixes. I am sorry but it will still be unofficial as we do not know when the official version be released.

Hi Aryan,

Yes, nRF Studio is able to program it with no problem... Everything seems to be working apart from that annoying message... I thought there was a new Sniffer Release (which there isn't), and it was complaining from the sniffer version rather than the Segger version...

RE: Sniffer for nRF52 DK

Susheel Nuguru — Wed, 30 Mar 2016 09:58:36 GMT

Hi Diogo, Are you having latest segger firmware, i did not understand why your programming failed?!!

RE: Sniffer for nRF52 DK

Diogo — Tue, 29 Mar 2016 16:28:27 GMT

Hi Aryan,

Would it be possible to get the same change of pin mapping for the last Sniffer firmware?

I tried the on you posted and I get a message saying: !!Your firmware is outdated!! Please upgrade (press CTRL-R).

Pressing CTRL-R will result on:

!!Programming Failed!! An error occurred while programming, you might need to program manually using nRFgo Studio.

I think the last firmware with just the uart remapping will do...

Thanks, Diogo

Hi. I have tried this Hex-File too and it works first but Wireshark shows only Advertising-Packets. In Sniffer.exe i have marked the Device i want to sniff but if it gets connected, no new Packets are shown. Any Suggestions? Sniffer.exe says Software V.1111, Firmware V.1, Nordic Plugin: version information unavailable, BTLE plugin V.1111. Wireshark has Version 1.12.10
