Enhanced Class 1 Bluetooth v2.1 Module

Every BT740 series Bluetooth® module from Laird Technologies is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT740 modules provide exceptionally low power consumption with outstanding Class 1 range via 18 dBm of transmit power. The modules support Bluetooth Version 2.1 specification, including Secure Simple Pairing (SSP), which improves security and enhances the ease of use for end customers. A broad range of Bluetooth profiles such as Serial Port Profile (SPP) and other vital features make BT740 modules superior to other Class 1 Bluetooth modules.


With a compact footprint of 15.29 x 28.71 mm, the modules deliver maximum range with a minimum size. Another integration advantage is the inclusion of a complete Bluetooth protocol stack with support for Multi-Point connections and numerous Bluetooth profiles, including Serial Port Profile (SPP), Human Interface Device profile (HID), and Health Device Profile (HDP). BT740 modules are fully qualified as a Bluetooth End Products, enabling designers to integrate the modules in devices without the need for further Bluetooth Qualification. In addition, each module carries FCC Modular, IC, and complete CE certification to further reduce the regulatory approval process for OEM integrators.


An integrated AT command processor interfaces to the host system over a serial port using an extensive range of AT commands. The AT command set abstracts the Bluetooth protocol from the host application, saving many months of programming and integration time. It provides extremely short integration times for data oriented Bluetooth applications.
In addition to the AT command set, the firmware also provides programming support for Multi-Point applications that use up to seven simultaneous data connections to, and from, the robust BT740 module. A low-cost developer’s kit makes it easy for an OEM to integrate the module and guarantees the fastest route to prototype and then mass production.

Approvals Bluetooth End Product Listing (EPL)
  FCC / IC / CE All BT740 Series

The BT740 is certified from compliance to various CE, FCC, Industry Canada and Bluetooth Special Interest Group. The grants, approvals, and formal test reports associated with these certifications may be leveraged by Laird Technologies customers to achieve their required device certifications. The degree to which customers can leverage these Laird Technologies Certification items is dependent upon the regulatory agency, industry body, and the type of end device.

If any additional information or guidance is required, please contact the wireless certifications group via email.


CE / ETSI

The BT740 Bluetooth Module has been tested for compliance to various CE and ETSI standards and specifications:

These formal test reports may be leveraged by mobile and portable device vendors as part of their self declaration to obtain the CE mark required by members of the European Union. ETSI/CE rules differ from those of the FCC and IC in that there is no provision for a modular approval. All approvals and certifications must exist at the device level rather than the module (radio) level.

The BT740 is fully compliant with Annex IV procedures in article 10.5 of R&TTE directive 99/5/EC.

The BT740 is fully compliant with European Union Directive 2003/95/EC or Reduction of Hazardous Substances (RoHS) as per our Declaration of Compliance. Click to view the Statement of Compliance to EU WEEE Directive and RoHS Directive.


FCC

Laird Technologies has received the following FCC grants for the BT740:

  • BT740-SC - FCC Part 15 Subpart C
  • BT740-SA - FCC Part 15 Subpart C

The above grants are Modular Approvals. Specific limitations are indicated on each grant.

When using this grant, the BT740 must be installed only in mobile devices (devices which typically operate at distances greater than 20cm, or 7.9 inches, from the human body). When certifying portable devices (those that typically operate at distances less than 20cm from the human body) a new grant must be secured by the device vendor.

NOTE: Laird Technologies test data may be leveraged by the device vendor to minimize the cost and time associated with the certification process.


Industry Canada

The BT740 is certified to the Industry Canada (IC) RSS-210 standard. IC 6616A-certification is based on FCC certification testing, using the same antennas and transmit power and covering the same frequency bands. 


Bluetooth SIG

The BT740 has received the Bluetooth SIG Qualification. The BT740 Qualified ID can be found, here. For more information visit the Bluetooth Special Interest Group website, here.
