Hi Will,

I got hold of a revision 3 PCA10056 now and tested, and did not get it working out of the box as with the older DK. However, if you use the USB connector on the long side it should work, and do so when I test. This is also in line with the documentation (though the other connector also works with older DKs):

I did not get this question. Can you elaborate?

Einar

Hi Einar,

No, it still did not work when I followed the instruction you shared(MSDDisable).

>> I can make sure the "MSDDisable".

>> The #2 board(New) is not working with MSD Disable and "2" Virtual COM Port.

>> The #1 board(Old) is working with MSD Enable and "1" Virtual COM Port.

>> Is there any possibility the VCP issue to be latched or Selected for the new one?

Looking forward to your reply!

Thanks,

Will

Hi Will,

I am unfortunately not able to test the nRF Sniffer with a new DK today, but I will try to get hold of one tomorrow and test on my end. In the mean time, a colleague of me suggested that it is worth trying to disable the MSD Device as explained here (copied from Segger wiki):

Start J-Link Commander
execute the following command (without quotes): "MSDDisable"
Quit J-Link Commander
Power-cycle J-Link-OB

Does that help?

Hi Einar,

Thanks for your reply,

How can I make the new DK board work for the BLE sniffer?

I have done the FW upgrade via nRF Connect for the Deskstop programmer, but it has not been detected by the Wireshark.

I can confirm my laptop's environment can work for the #1. (nRF52840-DK, Sticker Info.,PCA10056/ 2.0.1/2020.43) with FW((sniffer_nrf52840dk_nrf52840_4.1.0.hex).

Thanks in advance,

BRs,

Will

Hi Will,

The latest DK's use a nRF5340 as onboard debugger, and this do not support drag-and-drop programming. You will have to use other methods, like nrfjprog, nRF Connect for Deskstop programmer, or other suitable tools instead.
