L2CAP is used within the Bluetooth protocol stack. It passes packets to either the Host Controller Interface (HCI) or on a hostless system, directly to the Link Manager/ACL link. L2CAP’s functions include: Multiplexing data between different higher layer protocols.
So, what is Btsnoop HCI log?
The HCI log file is now being generated and is saved to /sdcard/btsnoop_hci.log. Note: Samsung devices have a slightly different location for the btsnoop file. There are two options for retrieving the HCI log from the Android device. The debug bridge is included with Android Software Developer Kit.
What is Bluetooth trace log?
DBus saves its debug information to this log file which can be useful to tell if both of the parties are able to communicate. HCI trace. In general the term “HCI trace” refers to the sniffed communication between the Bluetooth host (which means the software stack) and the Bluetooth controller (which means the chip).
What is a 4x MSAA?
Just go to the Developer Options screen and enable the Force 4x MSAA option. This will force Android to use 4x multisample anti-aliasing in OpenGL ES 2.0 games and other apps. This requires more graphics power and will probably drain your battery a bit faster, but it will improve image quality in some games.
What is a Bluetooth HCI snoop log?
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.
What does it mean to allow mock locations?
Its mainly used for development of apps that are going to use gps data. You enable it so you can test an app by having your phone show mock locations for your gps data to make sure the app is working correctly.
What is the Bluetooth stack?
A Bluetooth stack is software that refers to an implementation of the Bluetooth protocol stack. Bluetooth stacks can be roughly divided into two distinct categories: Embedded system implementations intended for use in devices where resources are limited and demands are lower, such as Bluetooth peripheral devices.
What does enable opengl traces do?
Tracer is a tool for analyzing your app’s OpenGL for Embedded Systems (ES) code. The tool allows you to capture OpenGL ES commands and frame by frame images to help you understand how Android is executing your graphics commands.
What is the Logcat?
Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log class. This page is about the command-line logcat tool, but you can also view log messages from the Logcat window in Android Studio.
What is opengl traces in Android?
Tracer is a tool for analyzing OpenGL for Embedded Systems (ES) code in your Android application. The tool allows you to capture OpenGL ES commands and frame by frame images to help you understand how your graphics commands are being executed.
What is SCO in Bluetooth?
Synchronous Connection Oriented link. The Synchronous Connection Oriented link is one of the two possible Bluetooth data link types defined. The SCO link is a symmetric, point-to-point link between the master device and a specific slave device.
What is host controller interface in Bluetooth?
Host Controller Interface (FireWire), an interface that enables a FireWire host controller to communicate with a driver. Host Controller Interface (USB), an interface that enables a USB host controller to communicate with a driver. Host Controller Interface (Bluetooth) in Bluetooth protocols.
What does GPU rendering do?
GPU rendering means, that there is used the power of GPU (Graphics card) for rendering, instead of CPU (processor). GPU rendering is incredibly fast and less power hungry.
What is Wi Fi verbose logging?
Verbose logging is a computer logging mode that records more information than the usual logging mode. (Verbose means “using more words than necessary”.) Verbose logging options are usually enabled specifically for troubleshooting because they create large log files and can slow down performance.
What does it mean to OEM unlock?
On the other hand, if you have “OEM unlocking” enabled, a failed update is no big deal. You (or a repair technician) could simply unlock the device’s bootloader and flash the factory images using fastboot, which would then overwrite the corrupt update and restore your firmware to working order.
What does Force 4x MSAA do?
Short Bytes: By activating Force 4x MSAA setting in Android Developer Options, you can enjoy a better gaming performance. It forces your phone to use 4x multisample anti-aliasing in OpenGL 2.0 games and apps. However, enabling this setting can drain your smartphone’s battery faster.
What is SDP in Bluetooth?
The Bluetooth Service Discovery Protocol. The Bluetooth SDP provides a means by which service applications running on different Bluetooth enabled devices may discover each other’s existence, and exchange information to determine their characteristics.
What is the OEM unlock?
OEM Unlock is a protective in Android Lollipop and later that is usually a step that users need to enable in order to officially unlock the bootloader of their device.
What is multiprocess web view?
Google’s WebView is a vital component of the Android OS that lets app developers render webpages in apps without requiring a full browser. On its developer page, Google mentions, “Starting with Chrome version 51 on Android N and above, the Chrome APK on your device is used to provide and render Android System WebViews.
What is a DHCP client android?
A device that uses DHCPv4 runs DHCP client software on a network (e.g., Ethernet or Wireless) interface. The DHCP client software contacts DHCP servers to obtain network configuration; in particular, it usually obtains a lease (a loan) of an IP address.
What is the definition of debugging?
Debugging is the routine process of locating and removing computer program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications.
What is the meaning of USB debugging?
Definition of: USB debugging mode. USB debugging mode. A developer mode in Android phones that allows newly programmed apps to be copied via USB to the device for testing. Depending on the OS version and installed utilities, the mode must be turned on to let developers read internal logs. See Android.
What is a host controller for USB?
A host controller interface (HCI) is a register-level interface that enables a host controller for USB or IEEE 1394 hardware to communicate with a host controller driver in software.
What is buffer size for logging Android?
Buffer Size. When recording audio into your computer, your sound card needs some time to process the incoming information. The amount of time allotted for processing is called the Buffer Size. Often times a smaller Buffer Size is desirable, however, not one that is too small.
