This document describes key hardware aspects of the Laird BT800 Bluetooth HCI/HID module. This document is intended to
assist device manufacturers and related parties with the integration of this module into their host devices. Data in this
document are drawn from a number of sources including data sheets for the CSR8510.
Because the BT800 is currently in development stage, this document is preliminary and the information in this document is
subject to change. Please contact Laird Technologies or visit the Laird website at https://connectivity.lairdtech.com/ to obtain

    The BT800 series of USB HCI devices are designed to meet the needs of OEMs adding robust Bluetooth
    connectivity and using embedded Bluetooth stacks within these products.
    Leveraging the market-leading CSR8510 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
    With a tiny footprint as small as 8.5 x 13 mm, yet output power at 8 dBm, these modules are ideal
    for applications where designers need high performance in minimal size. For maximum flexibility in
    systems integration, the modules are designed to support a full speed USB interface plus GPIO
    and additionally I2S and PCM audio interfaces.
    These modules present an HCI interface and have native support for Windows and Linux Bluetooth
    software stacks. All BT800 series devices are fully qualified as Bluetooth Controller Subsystem
    products. 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 integrated antenna and additional band pass filters.
    It further reduces regulatory and testing requirements for OEMs and ensures 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 pointing devices and / or keyboard functionality, requiring zero host device software or 
    Note: On the BT820, HID Proxy mode 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.
