  • Wireless output devices or wireless controllers for establishing wireless connectivity and for receiving digital content
    Patent number: 10768871
    Abstract: Output devices supporting wireless device discovery are herein disclosed and enabled. To setup an output device for wireless connection, wireless device discovery is performed by a client of the output device to discover the output device. Upon being discovered, the output device may provide identification or information related to the output device to the client for establishing a wireless connection. Subsequently, the output device may receive, via the established wireless connection, digital content from the client for output. Wireless device discovery operations may be based on one or more of a close proximity wireless communication, a Bluetooth wireless communication, or a wireless communication compatible with a protocol within IEEE 802.11 standards. Security information or authentication may be required for establishing the wireless connection. Subsequent to having established the wireless connection, the output device receives the digital content from the client for playing at the output device.
