Wireshark BLE Sniffer is not showing any packets during or after Peripheral connect

[Danjx]

I start the sniff and see packets from all advertising peripherals in the area.
I select my peripheral in the Device dropdown list.
Then I see a string of "ADV_IND" packets from my device only.
I have no Capture or Display filter active.
All well and good.

Then I enable my Central device and start the connect.
-> They connect without any trouble and start streaming data.
However all I see in Wireshark is a single "CONNECT_IND" packet. Nothing else.

--> I don't see any other packets!
Does anyone have any guesses as to what I'm doing wrong?
Driver/firmware/software versions perhaps?

Setup:

- Mac (Catalina)

- nRF51822 v2 (with Driver = Silicon Labs: CP210x Macintosh OS VCP Driver v6)
(note: dongle came preprogrammed from Adafruit, April 6, 2021)

- Wireshark v 3.4.4 (and Python v3.9.4)

- nRF_sniffer_for_bluetooth_le_3.1.0

Thank you in advance for any suggestions.

Hi Simon,

Again, the answer to your question is in my original post ....

"- nRF51822 v2 (with Driver = Silicon Labs: CP210x Macintosh OS VCP Driver v6)
(note: dongle came preprogrammed from Adafruit, April 6, 2021)"

So, why would I need the J-Link firmware if my dongle came preprogrammed?

Also thank you for the links, but they don't appear relevant to my problem. I can't find my problem even hinted at. What did you see that made you suggest these documents?

I got an email from Nordic that says you've been "assigned" to this case. But this does not appear to be your area of expertise. So is there someone there you could share with before your next reply? I'm really pressed for time.
