BT900 Series modules from Laird Technologies make it easy to add Classic BT and Bluetooth Low Energy (BLE)
functionality to small, portable, power-conscious devices, including those powered by batteries. The fully
approved, programmable modules feature Laird’s innovative, event-driven
smart BASIC 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 modules provide exceptionally low power consumption with outstanding wireless range, all within a
compact footprint of 19 mm x 12.5 mm. The modules incorporate all the hardware and firmware required to
support development of Dual Mode applications, including:

Complete radio hardware

UART, I2C, SPI, ADC, and GPIO interfaces

Embedded BTv4.0 software stack
-
Classic BT profile - SPP
-
GATT Client & Peripheral Modes
What makes the modules truly innovative is
smart
BASIC, an event-driven programming language that
enables standalone operation of the module. Laird has extended the implementation of
smart
BASIC from the
popular BL6xx series of single mode BLE modules into the BT900 series. This allows developers the flexibility
of utilising the Core and BLE specific
smart
BASIC functions from the BL6xx series to create fully
interchangeable BLE applications between these product ranges.
Without the need for any external processor, a simple
smart
BASIC 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
smart
BASIC accelerates initial development,
creation of prototypes, and mass production by providing you with your own Bluetooth expert within the
module.
In addition to carrying FCC modular, IC, CE and MIC approvals, BT900 modules are fully qualified as a
Bluetooth product, enabling designers to integrate the modules in devices without the need for further
Bluetooth testing. A low-cost developer’s kit including simple software tools simplifies module integration
and guarantees the fastest route to market.
