Can't get to promiscuous mode with dongle

[Engineer Cliff]

I'm using a Nordic nrf52840 based dongle to sniff the connection to a gamepad. When I bring up Wireshark connect options, it shows dashes in the promiscuous column, which I cannot change. I am running:
<pre>
npcap 1.80
JLink V7.94i
nrfutil 7.13.0
Wireshark 4.4.2 (v4.4.2-0-g9947b17309f4).
Windows 11 V 10.0.22631
sniffer_nrf52840dongle_nrf52840_4.1.1.zip

I have re-installed everything multiple times. Advertising packets come through just fine, but no others. I can run a game, which responds to the gamepad.

Any suggestions of where to look would be appreciated.

Hi

What is this gamepad you're trying to sniff the connection of exactly?

If it's a gamepad that has an existing encrypted connection it will be hard to sniff that, as you'll need the LTK or pairing/bonding passkey to sniff in on an already encrypted connection. If you have access to the pairing process itself you should be able sniff it though, but please share some more information on what you're trying to do here.

Some more info on common sniffing actions can be found in the nRF Sniffer for BLE user guide here: https://docs.nordicsemi.com/bundle/nrfutil_ble_sniffer_pdf/resource/nRF_Sniffer_BLE_UG_v4.0.0.pdf

Best regards,

Simon

I have an 8bitdo Pro 2 connected to my PC in "X" mode.  What I am trying to do is get bluetooth going on my Raspberry PI Pico W to control a car.  So, I want to sniff the interface, identify the buttons, and duplicate on my Raspberry Pi Pico.  The Pico is too underpowered for Linux, so I am having to do this myself.

I will go through the .pdf, to make sure I haven't missed anything. Thanks for that.
