NTRODUCTION

The Tetra module supports Bluetooth v4.0 for the Low Energy operation and Bluetooth v3.0 +

High Speed * for communication with existing Bluetooth devices. Tetra operates on the High Speed

(+HS) bandwidth via a XSR six pin JST connector. The interface is the USB HCI protocol. Tetra utilizes a serial EEPROM for retaining the Bluetooth Address, Country Code of operation, and previously paired Bluetooth devices. It stores the Bluetooth address and link key information on the module.

The slim design of Tetra features on-board, double helix, printed, antenna which addresses many antenna placement issues. The module is designed to be placed in areas that are small and slim offering optimum antenna placement. Also, instead of using RF cable assemblies and/or external antenna, the module can be placed using a low cost 6 wire cable assembly which is used to connect the module to the motherboard and host.

ESCRIPTION

TETRA Module

The Tetra module is a complete Bluetooth controller subsystem that includes the Bluetooth radio transceiver, Baseband, Link Controller and exposed HCI layer using USB. The Tetra module operates in the 2.4GHz ISM (Industrial, Scientific and Medical) band. The Tetra module utilizes a

CSR BlueCore® CSR8510 chipset solution. The CSR BlueCore® CSR8510 is a single-chip radio and baseband IC for Bluetooth 2.4GHz system. With the on-chip CSR Bluetooth Controller, the module contains the lower Bluetooth software protocol stack that is fully compliant Bluetooth with the v3.0+HS and v4.0 specification versions. The module dimensions measures 30mm x

6.5mm x 2.25mm. Power, Ground and USB communications are through a low profile, 6 pin, XSR

JST connector.

CSR Bluetooth Controller IC

BlueCore® CSR8510 is a product from CSR's Connectivity Centre. It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including EDR to 3Mbps. Dedicated signal and baseband processing is included for full Bluetooth operation. The CSR BlueCore® CSR8510 support the Bluetooth stack up to the HCI layer and the radio. The radio and baseband also supports High Speed and the Bluetooth v4.0 radio.

FCC warning statements:

 This device complies with Part 15 of the FCC Rules.

Operation is subject to the following two conditions: o o

This device may not cause harmful interference, and

This device must accept any interference received, including interference that may cause undesired operation.

 This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

 Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

 When integrated into a host equipment the host equipment should clearly display a label stating “this product contains FCC ID: R8KUGWT1BL1”

 The final Host product using this module will be subject to verification to FCC CFR 47 Part

TETRA Hardware Functional Description

The TETRA is a complete Radio Transceiver Module operating in the license free ISM (Industrial

Scientific and Medical) 2.4GHz band. The TETRA module is equipped with a crystal oscillator and

BALUN, Filter and a printed double helix antenna. TETRA incorporates CSR’s BlueCore®

CSR8510 chipset that is fully compliant to the Bluetooth v2.1+EDR, v3.0+HS and v4.0 specifications.

The full speed USB interface, power, and ground lines are connected via a XSR JST, low profile connector. The USB interface communicates with an external host running the upper Bluetooth stack defined by the Host Controller Interface (HCI) layer in the Bluetooth specifications. The USB interface is used to send HCI commands and events to and from the external host to TETRA module.

Asynchronous and Synchronous Bluetooth data is sent between the module and external host via the USB interface as well. Asynchronous data is sent and received over an Asynchronous packet switched RF link defined by the Bluetooth specification as “Asynchronous ConnectionLess” (ACL).

Synchronous data such as audio data uses “Synchronous Connection Oriented” (SCO) circuit switched RF links defined by the Bluetooth specification. ACL data links can retransmit lost or corrupted data continuously due to the packet switched connection. SCO data can provide fast reliable continuous synchronous data over the circuit-switched RF link. SCO over the USB is supported.
