Online BTSnoop Viewer

BTSnoop files are used to store Host Controller Interface (HCI) logs.

How to capture BTSnoop files

1. Linux with BlueZ: Run sudo btmon -w btsnoop.log.
2. Android: Enable Enable Bluetooth HCI snoop log in Developer options. Then save the logs locally, for example by running adb pull /data/misc/bluetooth/logs/btsnoop_hci.log.
3. Zephyr RTOS: Enable BT Monitor, for example with CONFIG_BT_DEBUG_MONITOR_UART=y, then capture the logs with btmon.

The generated files can later be opened in the ICHCI tool.
