COPE
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

ESCRIPTION
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
BT800 module
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.
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
BT820 USB dongle
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 configuration.
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.
Features and Benefits
Bluetooth v4.0 - Dual mode (Classic Bluetooth and BLE)
Compact footprint
2-wire and 3-wire Wi-Fi coexistence scheme

USB, GPIO, I2S, and PCM
Industrial Temperature Range
64 k EEPROM support for HID Proxy mode
Bluetooth Controller subsystem
FCC, IC, MIC, and CE approvals

ESCRIPTIONS

CS8510A10
(Main chip)
The BT800 is based on CSR8510A10 dual mode chip. The chip is a single-chip radio with on-
chip LDO regulators and baseband IC for Bluetooth 2.4 GHz systems including EDR to 3 Mbps.
Dedicated signal and baseband processing is included for full Bluetooth operation. The chip
provides SPI/PCM and USB interfaces. Up to four general purpose I/Os are available for
general use such as Wi-Fi coexistence or general indicators.
Note:
The purpose of the SPI interface is to access the module’s inner settings such as
selecting different WLAN CO-EXIST scheme and enabling HID proxy mode. The SPI
interface can also be used to put the module in RF test mode. You cannot use the
module over the SPI interface for normal operation as the main host interface.
Antenna
Band Pass
Filter
EEPROM
Crystal
BT800 – The antenna is a ceramic monopole chip antenna.
The band pass filter filters the out-of-band emissions from the transmitter to meet the
specific regulations for type approvals of various countries.
There are 64 k bits EEPROM embedded on the BT800 module which can be used to store
customizable parameters, such as maximum TX power, PCM configuration, USB product ID,
USB vendor ID, and USB product description. With that, the BT800 module can support
HID/HCI Proxy mode.
The embedded 26 MHz crystal is used for generating the clock for the entire module.
