The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner. For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies. A host operating system can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional ...
The exploits allow an attacker to connect to devices or systems without authentication and can give them "virtually full control over the device". Armis contacted Google, Microsoft, Apple, Samsung and Linux developers allowing them to patch their software before the coordinated announcement of the vulnerabilities on 12 September 2017. [154]
A wireless network interface device with a USB interface and internal antenna A Bluetooth interface card. A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network.
Long-range Bluetooth routers with augmented antenna arrays connect Bluetooth devices up to 1,000 feet (300 m). [2] With Bluetooth mesh networking the range and number of devices is extended by using mesh networking techniques to relay information from one device to another. Such a network doesn't have a master device and may or may not be ...
This renders the phone useless on that network and sometimes other networks, even if the thief changes the phone's SIM card. Devices without a SIM card slot or eSIM capability usually do not have an IMEI, except for certain early Sprint LTE devices such as the Samsung Galaxy Nexus and S III which emulated a SIM-free CDMA activation experience ...
An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto a eUICC chip. First released in March 2016, eSIM is a global specification by the GSMA that enables remote SIM provisioning ; end-users can change mobile network operators without the need to physically swap a SIM from the device.
In Windows 7, Bluetooth device settings have been moved to Devices and Printers from the Control Panel applet. Windows 8 expands its Bluetooth stack with support for Bluetooth 4.0 which includes Bluetooth Low Energy (BLE). [28] Windows 8.1 added developer APIs for Bluetooth Low Energy (GATT) and RFCOMM.
Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.
