6472.SuccessConnectionWireshark.pcapng

Hello,

Our production device is having issues with the BLE connection only identified with the Samsung S20+ model currently. We are using custom services for our phone App to communicate with our device. What is happening is that the connection is dropped quickly after the initial configuration handshaking occurs between the phone and our device. I observe the MTU exchange happening, but then the connection is dropped. 

Are there any known issues using the nRF52832 and the 1.9.1 BLE stack and specific Samsung phones?

Thanks for your help.

[Hung Bui]

Hi Pamela, 

Could you check if there is any log on the device ? 

Have you managed to reproduce the issue in house ? If you did , please try capture a sniffer trace , so we can investigate what could be wrong over the communication. 

Did it only happen on S20+ phone ? have you observed the same on other Samsung S models ?

[Pamela Keiles]

Hi Hung,

At this point we've only seen it on several S20+ and one S10+. From our device logging the connection is dropped following the MTU update exchange, but I have not been able to repeat it with my setup yet. I will test with an S20+ that I am receiving tomorrow to see if I can get more clues.

What is your recommended means for performing the a BLE sniffer trace? I do have some of the Nordic dev kit boards and have tried to use Wireshark briefly in the past, but found it confusing to easily follow the communications for a single device.

Thanks and regards,

Pam

[Hung Bui]

Hi Pam, 

It's would be very useful to have the sniffer trace. 

Please try to follow a connection by selecting the advertiser on the drop down list as instructed in the documentation. Please try with the latest version of the sniffer. 
Let us know if you have any problem. 

[Pamela Keiles]

Hi Hung,

I am not able to capture any packets past the adversing stage with my sniffer setup. I even tried re-installing the Wireshark tools, but still can only see advertisement and scan packets. 

As an example I have attached a scan capture file taken when a valid BLE connection completed. Can you tell me if you notice anything wrong with my setup used for capturing this file? Note I am using the nRF52DK board PCA10040 version 1.2.4.

Thanks for your help and regards,

Pam

[Hung Bui]

Hi Pam, 

You would need to select your device in the drop down list. Something like this: 

After that it should only follow the advertising of the device you want to follow. Only after that you should start the connection between the phone and the device. 

[Pamela Keiles]

Hi Hung,

Yes I tried selecting the correct device from the drop down box, but the sniffer is still not able to follow the connection process. Perhaps my dev kit board is too old and causing issues? I know it is an older version, I just ordered a newer one to try and see if it works any better.

Thanks,

Pam

Hi Pam, 
Please try to update the Jlink firmware and download our latest sniffer. 

Please try to test the phone with one of our example in the SDK to see if you get the same issue. 

[Pamela Keiles]

Hi Hung,

No luck getting this working. I just received a brand new nRF52-DK and now having different issues. First I am having problems getting the interface to be shown in the Wireshark capture options. Then when I do finally get it to show up somehow I get the following error messages:

Error by extcap pipe: FIFO does not exist!

nRF Sniffer for Bluetooth LE could not find interface: COM11

I have attached a Nordic sniffer log file for you to reference. Note that I also tried uninstalling and reinstalling the Wireshark program and even some python stuff. I also downloaded the latest Segger JLink program and updated the dev board JTAG firmware. 

Any help would be great, this is frustrating to say the least. Thanks for your help and regards.

Hi Pamela, 

Have you made sure you copied the extcap to C:\Program Files\Wireshark\extcap not C:\Users\pam\AppData\Roaming\Wireshark\ ? 

Please make sure you have installed the pyserial >v 3.5 

Also have you tried to run nrf_sniffer_ble.bat --extcap-interfaces in command line and check what show in the screen ? 

Please answer the question on:

What's the disconnect reason show on the peripheral side ? 

[Pamela Keiles]

Hello Hung,

We are not getting anywhere here, I have already gotten over the hump but need to get this sniffer working for future issues. Here is the answers to your questions:

Have you made sure you copied the extcap to C:\Program Files\Wireshark\extcap not C:\Users\pam\AppData\Roaming\Wireshark\ ? Yes

Please make sure you have installed the pyserial >v 3.5 Yes

Also have you tried to run nrf_sniffer_ble.bat --extcap-interfaces in command line and check what show in the screen ? Yes

What's the disconnect reason show on the peripheral side ? I believe there is a bug on the Samsung side, I have to play games with the stack to get around it. At this point I just want to get the sniffer working.

[Pamela Keiles]

Below are some other points worth mentioning.

I am able to get the capture at least started and somewhat working with an older nRF52-DK board, but it will not follow the connection process correctly. But with the brand new nRF52-DK board (version 3.0.0) I can't even start the capture process. One thing that is strange with the new board is the name of the J-Link firmware listed when I use the Segger Configuration tool, it is shown as OB-nRF5340-NordicSemiV1.00. This makes no sense since the board uses an nRF52832 chip and not a nRF5340. Is there any way the wrong firmware image for the J-Link was programmed on this board at manufacturing? Note that if I try to update it with the Configuration tool it states that it is up to date and I don't know how to manually force it to program with any other image.

[Hung Bui]

Hi Pamela, 

The firmware OB-nRF5340-NordicSemiV1.00 is actually correct. It's because on v3.0.0 we use a nRF5340 as the interface chip instead of using the Jlink chip. So the target device is still nRF52 but the programmer/debugger is a nRF53.

However, I did a test with a v3.0.0 board like your and got the same issue. Wireshark couldn't detect the board. I suspect there is a compatibility issue between the extcap library we have and the new board. I will report this to the team to find a solution. 

In the mean time, please try the suggestion from this ticket.  for the old board. Could you let me know the version of your board ? I remembered the I experienced the same issue a long time ago but haven't seen that in the last few years. 

Also you can try to get hold of a nRF52840 dongle (PCA10059). For the dongle , there is no update lately so I believe the sniffer should work. 

Also please try to debug without the sniffer. Please try to test with a stock SDK example.
