# Bluetooth * We can enable Bluetooth HCI logging from developers options and then do some BLE stuff and there will be a file called `btsnoop_hci.log`. * `/etc/bluetooth/bt_stack.conf` is the file that hold all the information about the bluetooth configuration. * If rooted phone: `adb shell su` gives you the root access * But even then we cannot edit that file manually. * Chances are that we might not be able to directly pull the `btsnoop_hci.log` via `adb pull `. * Best solution is to get sudo shell and copy that file to `/sdcard` * Then run `abd pull /sdcard/btsnoop_hci.log` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
