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.

    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.

    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.

    Hi Hung,

    I finally got the sniffer working properly with the older nRF52-DK board. The issue was the JLink driver needed to be updated. So after checking the version and updating the JLink driver via the Segger Configurator tool, I was then able to follow the traffic for a specific device properly.

    You should definitely get the dev team to follow up on the 3.0.0 version boards not working correctly with the sniffer, my local apps engineer experienced the same issue. At this point however you can close this specific case.

    Thanks and regards,

    Pam

    Hi Hung,

    Actually maybe it would be best to have you guys look into the original issue of this case, which is certain Samsung phones dropping the BLE connection immediately after the MTU exchange occurs with our device using a nRF52832. I now do have a trace of the connection drop and it would be helpful to have some input on what was captured, the connection starts on item # 7840 of the capture. I'm having a hard time trying to figure out how to upload this file, so let me know if you can't find it.

    Thanks and regards,

    Pam
