Bluetooth modules live through oil depot fire
Ezurio has always prided itself on its robust Bluetooth solutions, which are designed for applications demanding the best performance.
Modules bring M2M comms to wireless LANs
Ezurio chose the Embedded Design Show in San Jose to release the first in a range of 802.11b/g modules designed specifically for the embedded market.
Using Ezurio's Bluetooth modules, voice based products with a range of up to 100m can be readily achieved.
Almost every Bluetooth headset on the market today is based around a few reference designs from the leading silicon manufacturers.
These are generally ROM based implementations that provide limited flexibility and which are aimed at volume consumer products.

Bluetooth modules enhance automotive security
A new car security system that identifies car owners through the Bluetooth element of their mobile phones is set to revolutionise the fight against car thieves.
However, the popularity of Bluetooth is enabling voice applications in many other areas where greater functionality is required, such as medical devices, professional headsets and specialist intercoms.
Until this point, development of these specialist voice applications has required a detailed understanding of the Bluetooth standard and expensive development equipment.
With the introduction of its range of voice codec evaluation boards, which complement the Wireless Development Kit, Ezurio has changed the development process for headset and hands-free applications from a complex design task to a simple implementation.
The range of three codec boards provides a fast route to designing complete hands-free compliant headset solutions.
The three evaluation boards cover all the different Bluetooth voice codec options.
Ezurio's voice codec evaluation boards allow developers full access to the features of these codecs, giving maximum opportunity to customise and differentiate products.
Novel Bluetooth voice products typically need to implement the functionality of the Bluetooth hands-free profile in a host microprocessor.
To help this development, Ezurio's voice codec boards are supplied with an example script in their UWScript language.
This runs on a PC within Ezurio's terminal emulator to demonstrate a complete Bluetooth hands-free implementation.
Ezurio's Bluetooth modules are fully approved as Bluetooth end products, as well as having modular FCC and CE approval.
The example hands-free script has been certified on the latest Bluetooth Profile Test System.
For product designers this minimises their approvals costs and time, providing the fastest route to market for Bluetooth voice products.
Ezurio's range of Bluetooth modules have a fully integrated Bluetooth protocol stack and a comprehensive set of AT instructions making them simple to program.
They support version 2.0 of the Bluetooth standard, including Enhanced datarate and Extended SCO for improved voice quality.
The integrated high performance ceramic antenna gives open field ranges for voice applications that are in excess of 100m.
