Ellisys Bluetooth Explorer 400 All-in-One Bluetooth Protocol Analysis System |
||
Whole-band BR/EDR and Low Energy sniffer, with concurrent capture of spectrum, HCI (USB, UART, SPI), WCI-2, logic signals, and Audio I2S.
Features:
|
Traffic analysis is one of the key day-to-day activities for Bluetooth engineers looking to rapidly test and debug their prototypes and products. Unfortunately, Bluetooth over-the-air sniffing has always been difficult to perfect. Legacy sniffing methods suffered from major technological drawbacks, making them unreliable and even unusable in several circumstances, making Bluetooth engineers' tasks much more difficult. With its revolutionary whole-band Digital Radio, Ellisys lifts protocol capture and analysis to new heights, radically overcoming the drawbacks of those legacy approaches to Bluetooth sniffing. The Ellisys all-in-one whole-band sniffer robustly records any packet, at any time, from any neighboring piconet, with zero-configuration and without being intrusive.

| Ellisys Instant Piconet is a unique feature that is only made possible by the use of Ellisys Rainbow hardware capture technology. As soon as the analyzer starts recording, the Instant Piconet view displays the current topology of physical channel characteristics created by all neighboring devices. Piconets, scatternets, pagings and inquiries are displayed using symbols inspired by the Bluetooth specification and augmented with relevant information: data transfer activity and throughput for both master-slave and slave-master directions, per device RSSI, device names and addresses, etc. |
 Instant Piconet |
|
| When using the Ellisys analysis application, Ellisys Instant Timing quickly becomes the central feature that one cannot imagine being deprived of, and that makes one wonder how it was ever possible to work without it. This view displays all captured packets as time ordered interactive graphical elements. Length represents duration, while height is proportional to data rate (basic or enhanced). Packets are color-coded for type, master/slave direction, error status, device sending or receiving the packet, etc. Slot durations are also represented. |

| The easiest way to access any layer of the complex Bluetooth protocol and profile stack is the Ellisys Protocol Overview. This view displays all desired protocol elements in an easy-to-browse hierarchical tree view. The exact level of protocol decoding is easily configurable. It is searchable at will, and all columns can be used as filtering criteria to drill down data. Any fields displayed in the companion Detail Pane can be added and displayed as a whole column, for instant values comparison and custom filtering. |

Traffic analysis is one of the key day-to-day activities of Bluetooth engineers looking to rapidly test and debug their implementations. Unfortunately, Bluetooth over-the-air sniffing has always been some difficult task topic. Legacy sniffing methods suffered from major drawbacks, making them unreliable and unusable in some circumstances, therefore making Bluetooth engineers' lives difficult.

With its Bluetooth® Explorer, Ellisys lifts protocol capture and analysis to new heights, radically overcoming drawbacks of those legacy approaches to Bluetooth sniffing. The new Ellisys All-Channel sniffer robustly records any packet, at any time, from any neighboring piconet, with zero-configuration and without being intrusive. With the right tool, your Bluetooth Days will not seem too short anymore! |

| Why were Bluetooth systems previously so difficult to sniff? | ||
|
Bluetooth wireless technology was originally designed to be robustly impervious to interference on the much-used ISM 2.4 GHz band, and was also designed to be non-easily sniffable for security reasons. The two main RF characteristics unique to the Bluetooth specification are:
A standard Bluetooth radio can receive or transmit on only one of the 79 channels at a given time. Legacy Bluetooth sniffers used a standard single-channel radio. Because of this inherent limitation, those sniffers had to connect to a piconet's master device using a mandatorily configured 48-bit |
address, retrieve the master's
clock, and eventually follow the hopping sequence based on this
information. Main drawbacks of this approach were:
Ellisys has created a revolutionary sniffer that overcomes all those drawbacks and adds innovative features, opening new horizons to Bluetooth debugging and interoperability testing. |

Revolutionary Ellisys Rainbow All-Channel Capture Technology |
||
| This multi-protocol, multi-band and multifaceted protocol analysis system is powered by the revolutionary Ellisys Rainbow all-channel capture engine. With this breakthrough technology, Ellisys hardware is capable of capturing concurrently all 79 BR/EDR channels as well as all 40 Low-Energy channels, plus related HCI traffic for cross-analysis. |
 Former single-channel capture |
|
| With this method the Ellisys Bluetooth® Explorer does not need to follow the hopping sequence of a given piconet; it can receive any packet from any neighboring device! Smart post-capture analysis groups packets into physical channels and determines devices states, displaying useful high-level information on master and slaves. |
 Ellisys Rainbow All-Channel Capture |
|
| The above illustrations show how legacy sniffers received packets by listening to a single channel at a time, compared to the Ellisys Rainbow All-Channel capture catching all Bluetooth packets by listening to a 80 MHz wideband frequency range concurrently | ||
| What about security? | ||
|
Ellisys developed smart security algorithms to further ease engineers' lives. The Ellisys software application will automatically determine PIN codes and Link Keys when pairing are detected. Resulting link keys can be stored, such that any further traffic capture from the same devices will be decrypted automatically. SSP (Simple Secure Pairing) is also supported. |
SSP uses encryption methods similar to the methods used on the Internet, to secure sensitive information exchanges, such as banking transactions. No algorithm can help automatically determine the keys for decrypting packets. The link key must thus be specified to the analysis software for decryption. Ellisys eases this process by automating link key extraction from HCI traces. |
