"Go" Bluetooth packet capture

Here's a way to capture Bluetooth packets on Android

1. Prerequisites

First of all, you have to have an Android phone
Then your Android system version will be at 4.4 and above

I have not done Android development, I do not know how the developers grasp the Bluetooth package
But I know I can use Hcidump to crawl Bluetooth packets.
This method is not described here (follow-up may be possible to understand)

2. Turn on function

There is a feature in the developer options
-[Enable Bluetooth HCI snoop log/enabling bluetooth® HCI information collection log]
Turn it on.

3. Grab Bag

Then you can do a variety of Bluetooth operations, after the end of the capture package file is in
/sdcard/btsnoop_hci.log

Copy it out and put it on the computer, you can see it directly with Wireshark.

You can use filters such as Bthci_acl, Btl2cap, BTHFP, and so on to filter the packets to see the protocols you care about.
