The most advanced, most comprehensive Bluetooth protocol analyzer ever made.Building on a legacy of innovation, the Bluetooth Vanguard All-In-One Protocol Analysis System delivers new advances designed to ease the increasingly complex tasks of Bluetooth developers.HighlightsVanguard provides synchronized capture and analysis of BR/EDR, Bluetooth Low Energy, Wi-Fi 802.11 a/b/g/n/ac (3x3), WPAN 802.15.4 (all 16 2.4 GHz channels), raw 2.4 GHz RF spectrum analysis, HCI (USB, UART, SPI), generic SPI/UART/I2C/SWD communications, WCI-2, logic signals, and Audio I2S.
Capturing wireless traffic is of course the primary aspect of Bluetooth debugging, but other information can often be just as important to fully understand the big picture. For example, external GPIOs, HCI traffic, Wi-Fi and WPAN traffic, or raw spectrum information can all be critical to capture concurrently with the Bluetooth traffic. This is another aspect where Ellisys sniffers truly excel. Fully integrated hardware is a design choice, and for good reason. This means better control of the capture characteristics across wired and wireless communications, especially timing synchronization. The net result is that Vanguard supports one-click concurrent and tightly synchronized capture of |

Reconfigurable Bluetooth Digital RadioThe reconfigurable radio concept for Bluetooth analyzers is another innovation from Ellisys engineering. With the Bluetooth Vanguard, this cost-saving feature remains a core user benefit. Reconfigurability means that the analyzer can be updated by software to support new features, without any change to the hardware. For instance, this flexibility allowed for the addition of next-generation Bluetooth features such as enhanced AES security, Connectionless Broadcast, and recent features, like Coded PHY and the 2Mbps BLE speed enhancement, many months before these features were released in an updated specification.. This concept has greatly improved and accelerated the overall development cycle for Bluetooth technology. With legacy solutions, Bluetooth engineers had to test new features with old analyzers that employed prior-generation radios, effectively an impossible task. With the Ellisys reconfigurable Bluetooth digital radio, support for new features are available at a very early stage, well before specifications are released. This approach helps Bluetooth radio development teams ensure proper operational characteristics well before the specification is final, and well before final spins. This dramatically improves the quality and interoperability of Bluetooth products employing new features and speeds the development cycle.

Wi-Fi Capture using a Hardware-Accelerated Protocol EngineWith Vanguard, Wi-Fi is captured using an innovative, Ellisys-designed hardware-accelerated protocol engine. With lower-performance Wi-Fi capture tools that use a software-based capture approach, such as that which can be done with just about any computer, the capture process is done with a processor involved. This approach can limit the speed and timing accuracy of the capture – packets can be missed when the processor is outmatched by the incoming streams. With Vanguard’s specially designed protocol engine, the capture is driven directly and without processor dependence to guarantee throughput and minimize latency. |

All-Channels Capture of 802.15.4 WPANIEEE 802.15.4 is a technical standard that provides the lower-layer support of higher protocols network specifications like Thread, Zigbee, 6LoWPAN and RF4CE. Increasingly, this Low-Rate Wireless Personal Area Network (LR-WPAN) technology is being used on devices, modules, and SoC’s that also employ Bluetooth and/or Wi-Fi.. The Bluetooth Vanguard captures all 16 WPAN channels used in the 2.4GHz band, including associated RF characteristics, all in precise synchronization with all other traffic streams captured by the analyzer.

Understanding Coexistence IssuesWi-Fi and WPAN are common sources of interference with Bluetooth communications, as much of the spectrum used by these standards is the same as that used by Bluetooth. To properly characterize these contentions, Vanguard provides capture of Wi-Fi 802.11a/b/g/n/AC 3x3 and WPAN in precise synchronization with all other supported wired and wireless transmissions. Understanding interference sources and related hardware and stack behaviors, how Bluetooth devices attempt to avoid these interferences, and the negative effects these interferences have on Bluetooth performance and interoperability is an important task for many Bluetooth engineers. Additionally, Wi-Fi, WPAN and Bluetooth are often co-resident on a single chip, and this design approach presents substantial test and operational challenges. Vanguard has a variety of innovative features designed to enable engineers to manage these challenges. Understanding the timings of Wi-Fi transmissions, the timing of these transmissions relative to Bluetooth packets or wired interfaces such as HCI or discrete logic inputs, the power levels of these transmissions, and packet details, is quite important to the general task of ensuring proper radio coexistence.

Bluetooth Mesh NetworkingThe Bluetooth Mesh Networking specifications define a broad spectrum of device and systemic requirements for a large-scale many-to-many network using Bluetooth Low Energy wireless technology. Bluetooth mesh networks can greatly increase the range of Bluetooth communications by using a message relay approach and are inherently uncomplicated and inexpensive to deploy, as there are no requirements for a central router or computer. The Bluetooth Vanguard provides support for capture, decode, and decryption of Mesh features, including a variety of mesh-specific security mechanisms and protocols.

Emerging Features SupportThe reconfigurable Bluetooth analyzer is an Ellisys innovation. All Ellisys Bluetooth analyzer systems are reconfigurable with software updates. Ellisys maintains close relationships with radio developers worldwide and with the various technical groups involved in outlining new Bluetooth features and specifications. This approach allows new features to be added even in the conceptual stages, long before such features become standardized in a public release of the Bluetooth specification. This is a huge advantage to Bluetooth radio developers, and to the Bluetooth developer ecosystem in general, as radio developers can test new features well before they are committed to silicon, greatly reducing chances of re-spins or discoveries of issues in the marketplace, post-spin. This also raises the quality aspects of general Bluetooth radio development, effectively bringing a better product to integrator companies, and in the end, better products to consumers.

Choices in Power and ControlVanguard conveniently provides multiple choices to the user for system control and power. Conveniently, the user can control and power Vanguard using networkable Gigabit Ethernet (1GbE) which utilizes Power over Ethernet (PoE), or USB Type-C™, which utilizes Superspeed USB 3.1 Gen 1 (5Gbps) and USB Power Delivery. As needed, the user may also operate and power the system using an external DC supply (provided).
