It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones.īluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. It employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft). Here example how it can looks (note about brcm/brcmfmac4356-pcie.Typically less than 10 m (33 ft), up to 100 m (330 ft).īluetooth 5.0: 40–400 m (100–1,000 ft) īluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). Without WiFi firmwareīluetooth will not initialize and will not work properly.įirmware for WiFi already included to kernel, but you may need to do additional These devices requires two kinds ofįirmware - first for WiFi, and second for Bluetooth. WiFi chipset (this can be BCM43XX 802.11ac Wireless Network Adapter or just Some Bluetooth controller (for example, BCM4354 and BCM4356) are integrated to Notes about combined WiFi+Bluetooth devices Here quick naming convertion: Original name There may be incorrect naming between presented firmware name and name You may list all Bluetooth devices like this:īluetooth: hci1: BCM20702A1 (001.002.014) build 0000īluetooth: hci1: BCM20702A1 (001.002.014) build 1467īluetooth: hci1: Broadcom Bluetooth DeviceĬongratulations, now your bluetooth device successfully loaded. When you inserting Broadcom Bluetooth device you prefered Linux distribution There are autogenerated DEB and RPM packages for RedHat and Debian based distributions.
InstallationĬheck your Linux distribution repositories. As a repository maintainer, I cannot provide security fixes. You will have to use these devices at your own risk. Since Broadcom has stopped active support for its consumer devices, your system may be subject to security risks. Recently several vulnerabilities have been discovered in the Bluetooth stack such as CVE-2018-5383, CVE-2019-9506 (KNOB), CVE-2020-10135 (BIAS) and more. Since February 2017, Broadcom ships their drivers directly to Windows This package intentended to provide firmware of Broadcom WIDCOMM® Bluetoothĭevices (including BCM20702, BCM20703, BCM43142 chipsets and other) for Linux Broadcom Bluetooth firmware for Linux kernel
