In Android 4.4 and later, you can manually collect BTSnoop logs, which resemble the snoop format in RFC 1761. These logs capture the Host Controller Interface (HCI) packets. To log all data, the user needs to enable Bluetooth HCI snoop by doing the following: Enable Developer options on the device.
Retrieving the HCI LogOn the Android device go to Settings.Select Developer options.Click to enable Bluetooth HCI snoop logging.Return to the Settings screen and select Developer options.In the Developer options screen select Enable Bluetooth HCI snoop log. The log file is now enabled.
Bluetooth HCI snoop log: The ‘Enable Bluetooth HCI snoop log’ allows you to capture and analyze Bluetooth HCI (Host Controller Interface) packets. Enabling this will places them for analysis in a file on the device storage (/sdcard/btsnoop_hci. log) for retrieval.
Enable Bluetooth HCI snoop log: Sometimes, a developer (or security specialist) will need to capture and analyze Bluetooth HCI (Host Controller Interface) packets. Enabling this will place them in a file on the device storage (/sdcard/btsnoop_hci. log) for retrieval.
A BluetoothHCI (Host Controller Interface) snoop log is a log file that contains all the Bluetoothtransmissions that you have made on your android gadget.
Buffer size: A general rule is that a buffer size of 10 MB per CPU core allows for a trace that’s about 20 seconds long. For example, if a device has a two quad-core CPUs (8 cores total), an appropriate value to pass into the systrace program is 80,000 KB (80 MB).
When a device is in USB Debugging mode, a computer connected to the device can read all data, run commands, and install or remove apps. The security of the device settings and data could be compromised.
Force GPU rendering This will use your phone’s graphics processing unit (GPU) rather than software rendering for some 2D elements that aren’t already taking advantage of this option. That means faster UI rendering, smoother animations, and more breathing room for your CPU.
Logger Buffer Sizes option allows you to change the buffer size of these mentioned buffers. Increasing the buffer size would allow you to capture more logs in the buffer, and reducing the probability of an overwrite in case of high-frequency logs. Setting the option to “OFF” would disable logging.
Trustwave recommends that mobile devices should not be set to USB Debugging mode. When a device is in USB Debugging mode, a computer connected to the device can read all data, run commands, and install or remove apps. The security of the device settings and data could be compromised.
A debug menu or debug mode is a user interface implemented in a computer program that allows the user to view and/or manipulate the program’s internal state for the purpose of debugging.
