The BT900-US USB Dongle has been developed to take advantage of the BT900-SA module, providing a simple
and easy way to add Classic Bluetooth, BLE Central, and BLE Peripheral mode to virtually ANY operating system
with a USB interface. Leverage the BT900-US to enable any Bluetooth SPP device or BLE sensor to communicate
to any PC, laptop, or mobile computer without any complicated installation or software support requirements.
The fully-approved, programmable dongle features Laird’s innovative, event-driven
smartBASIC
programming
language which significantly reduces OEM development risk and speeds time to market.
Based on the Cambridge Silicon Radio (CSR) 8811 silicon and a low power Cortex M3 microcontroller, the BT900-
US provides exceptionally low power consumption with outstanding wireless range. The dongle incorporates all
hardware and firmware required to support Bluetooth dual-mode applications in a computing environment
including:
Complete, packaged radio hardware
Simple, universal USB to Virtual COM port emulation via FTDI 232R chip
Embedded BTv4.0 software stack
–
Classic BT profile - SPP
–
GATT Client and Peripheral modes
What makes the modules truly innovative is
smartBASIC,
an event-driven programming language that enables
standalone operation of the dongle. Laird has extended the implementation of
smartBASIC
from the popular
BL6xx series of single-mode BLE modules into the BT900 series of modules and now the BT900-US dongle. This
allows developers the flexibility of using the Core and BLE-specific
smartBASIC
functions from the BL6xx series to
create fully interchangeable BLE applications between these product ranges.
Without the need for any external processor, a simple
smartBASIC
application encapsulates the complete end-
to-end process of reading, writing, and processing of sensor data and then using Classic Bluetooth or BLE to
transfer it to/from any Bluetooth device. Ultimately
smartBASIC
accelerates initial development, creation of
prototypes, and mass production by providing you with your own Bluetooth expert within the device.
In addition to carrying FCC modular, IC, and CE approvals, the BT900-US is qualified by the Bluetooth SIG which
enables designers to integrate the dongle without the need for further Bluetooth testing.
