OK, I see. I see you got hold of the installer so it is solved for now, but in case you want to digg deeper it would be interesting to know more about how you reproduce this.

Note that once the DK has been programmed with the sniffer firmware, you need to connect to the nRF USB port on the bottom side, and not use the IMCU USB port on the left side (this can be left disconnected).

The problem we were having is that the BLE logger kept coming up as a COM port instead of the BLE Sniffer. We use a python script to automate the test which opens up Wireshark, looks for the BLE Sniffer in the COM ports and then runs the BLE Sniffer in Wireshark to get an RSSI value.

Hi,

The old sniffer software is no longer available. It would be interesting to look at the problem you have with the new software, though. Can you try to delete the content of your personal extcap folder and bootstrap it again? See Installing nRF Util plugins for details.

I've now managed to find some legacy BLE Sniffer software and have installed it on the new computer. It is now working the same as the old computer and therefore we are now able to do our BLE testing.
