The BT800 series of USB HCI modules and packaged dongle are Laird’s first dual-
mode Bluetooth v4.0 offerings, bringing support for Classic Bluetooth and Bluetooth
Low Energy (BLE) in a tiny package.
Leveraging the market-leading CSR 8510 chipset, the BT800 series provides
exceptionally low power consumption with outstanding range. Supporting the latest
Bluetooth v4.0 Specification with EDR (Enhanced Data Rate), the Laird BT800 series
enables OEMs to accelerate their development time for leveraging either Classic
Bluetooth or Bluetooth Low Energy (BLE) into their operating system based devices.
The BT800 has a footprint as small as 8.5 x 13 mm, yet output power at 8 dBm. This
makes these modules ideal for applications where designers need both performance
and minimum size. For maximum flexibility in systems integration, they are designed
to support a full speed USB interface plus GPIO, plus I2S and PCM audio interfaces.
These modules present an HCI interface with native support for Windows and Linux
Bluetooth stacks. All BT800 series devices are fully qualified by the Bluetooth SIG. This
also allows designers to integrate their existing pre-approved Bluetooth Host and
Profile subsystem stacks to gain a Bluetooth END product approval for their products.
The BT800 series is engineered to provide excellent RF performance with an
integrated antenna and additional band pass filters to further reduce the regulatory
and testing requirements for OEMs, ensuring a hassle free development cycle. As an
additional benefit of the BT800 series, Laird has implemented CSR’s HID (Human
Interface Device) Proxy Mode enabling out of the box HID connectivity for BLE
pointing devices and / or BLE keyboard functionality, requiring zero host device
software or configuration.
The BT820 is a packaged dongle version of the BT800 module that allows OEMs to
plug the device into any Windows or Linux device that supports USB connectors and
an inbuilt Bluetooth software stack in its operating system.
NOTE: HID Proxy mode on the BT820 works with “Just Works” devices and will not
pair with BT devices that require a pincode or passkey.
A fully featured, low-cost developer’s kit is available for prototyping, debug and
integration testing of the BT800 series modules and further reduces risk and time in
development cycles.
