What is the output of the following commands, after you have inserted the dongle. I want to capture bluetooth (I connect bluetooth headset to my pc) wireshark show bluetooth network connection but when I start capturing. How does your kernel detected that dongle? Is it a network device? I am able to capture that other bluetooth dongle I have, but I cannot see that Bluetooth LE USB dongle. If you don't see the device in the output of dumpcap, it's not supported by WinPcap. In that case WinPcap won't see it either. The idea here is that HTTPS traffic that travels over the Internet is confidential, a random router. Another useful tool is Wireshark to give a graphic view of the snooped data. This is because HTTPS encrypts point to point between applications. Figure 2- launch bluetooth Manager Figure 3 - bluetooth Manager. Wireshark is not able to decrypt the content of HTTPS. The thing with HTTPS is that it is application layer encryption. You started the WinPcap NPF driver before you inserted the USB dongle. Wireshark captures all traffic on a network interface.Not much you can do about that, except adding Bluetooth support to WinPcap yourself. It is not detected and thus not support by WinPcap.So, if the dongle does not appear on the list of devices, there are two possible reasons:

As there is no native Bluetooth support in WinPcap, it will only work, if the Bluetooth device driver makes the device look like a network interface to the OS and WinPcap. WinPcap will only be able to capture on supported devices (obviously). wireshark Project information Project information Activity Labels Members.

It is not listed in the list of interfaces.
