I have a ring (worn on finger) that monitors heart rate and body motion and then sends that data via Bluetooth Low Energy to an app on my smartphone (Samsung Galaxy, Android Version 13). I am activating the Bluetooth HCI snoop log on my smartphone. Once I access this file (Bluetooth HCI snoop log) and then transfer it to my Windows 11 laptop computer, how do I then download that file into Wireshark so that I can then analyze the Bluetooth data in that file on Wireshark? I know that this can be done because I have seen a few tutorial videos where it was done, but no showed how to download the Bluetooth HCI snoop log file into Wireshark. Thank you for your time.

There are two HCI log files attached to 2237: add support for "btsnoop" log format.
Can you open either in your version of Wireshark?

Transferring the file to your Windows 11 laptop is "downloading" the file.

Once you've downloaded the file from the phone to your laptop, you then open the file in Wireshark, just as, if you've downloaded a PDF, Word document, Excel spreadsheet, etc. from a web site, you then open it in Acrobat or Word or Excel or....

And you open capture files in Wireshark the same way that you open PDFs in Acrobat or Word documents in Word, or Excel spreadsheets in Excel or...:

  1. You may be able to open the file by double-clicking the it in a File Explorer window for the directory into which you downloaded the file. That will depend on the extension of the file's name; if, when you installed Wireshark, you told the Wireshark installer to register various file types (with a list of extensions shown), if one of those extensions is the extension of the file, double-clicking the file should open it in Wireshark.
  2. If that doesn't open the file in Wireshark, try doing File > Open in Wireshark and then browse for the file. If you find it, click the "Open" button in the "open file" dialog.

Found on :

"Wireshark, a network protocol analyzer, can be used to peek into the file. You just need to retitle the file to *.cap and open it."

So it looks like the file extension of the log file is not one associated with Wireshark by default, so they advice to change the extension (so you can double click it), but option 2 above should also work.
