The Bluetooth Vanguard now includes features that address the recent, rapid evolution of Bluetooth technology and related development complexities, including feature additions for Wi-Fi and WPAN coexistence analysis. Vanguard is an all-in-one, fully integrated system supporting wideband (all channels) capture and analysis of Bluetooth Classic (BR/EDR), Bluetooth Low Energy (LE), plus concurrent Wi-Fi 3×3 11ac, all 16 WPAN (IEEE 802.15.4) 2.4 GHz channels, raw ISM spectrum capture, Bluetooth host controller interface (HCI) protocols (USB, UART, and SPI), Audio I2S, WCI-2, and generic protocols including UART, SPI, I2C and SWD, all visualized over the widely adopted Ellisys software suite.
Bluetooth Vanguard provides various features to enable precise understandings of spectrum and channel usage by devices and a host of other features specific to coexistence testing. These features include a raw RF capture of the ISM spectrum that provides precision time and power indications of Bluetooth packets and all other emissions, an Ellisys innovation. Additional features include GPIO logic capture, Wi-Fi protocol capture (IEEE 802.11 a/b/g/n/ac 3×3), WPAN capture (IEEE 802.15.4, all 16 channels), and support for the Wireless Coexistence Interface (WCI-2) Transport standard, all tightly synchronized to Bluetooth and host controller interface (HCI) packets and concurrently captured.
Central to wireless coexistence testing and characterization are various correlations of Wi-Fi traffic to Bluetooth traffic, including the ability to manage streams of incoming traffic without loss. With implementations that use a software-based capture, such as those that can be done with just about any computer, the Wi-Fi capture is done with a processor involved. This limits the speed and accuracy of the capture – packets can be missed when the processor is outmatched by the incoming streams. With Vanguard, the capture is driven directly with a powerful hardware-accelerated protocol engine, to guarantee throughput and minimize latency.
The Ellisys Bluetooth Vanguard is designed with a reconfigurable capture engine, an Ellisys innovation introduced with the Bluetooth Explorer™ model in 2010. This feature allows for early addition of analyzer support for emerging Bluetooth features, well ahead of official releases in the Bluetooth specifications. For example, features peculiar to Bluetooth 5, including 2 Mbps speed and LE Coded PHY extended range enhancements, were released 18 months prior to the public release of that specification. This approach enables design teams to test and perfect new Bluetooth features at an early stage, allowing for improved development cycle efficiencies and increased confidence in product quality on the roll out of new radios and stacks.
