Description

WT21 is intendend for Bluetooth applications where

a host processor is capable of running the Bluetooth

software stack. WT21 only implements the low level

Bluetooth Host Controller Interface (HCI) but still offers

advantages of a module - easy implementation and

certifications. As based on CSR’s BlueCore-6 chip, WT21

offers the lowest current consumption and the highest

integration level in its class. WT21 is also fully ready to

support the latest Bluetooth 2.1 standard.

WT21 also has CSR’s AuriStream technology built in,

which significantly improves the quality of voice in audio

applications.

WT21 supports any Bluetooth software stack that

implements the standard Bluetooth HCI interface. The

software stack can interface to the module either via

UART, SDIO or SPI interface.

WT21 offers Bluetooth in integrated form factor that

is easy to understand, manage and source. It is an

ideal product for an OEM who does not want to spend

significant amount of time and money to RF regulatory

approvals and designing a complex 2,4 GHz radio

product.

By utilizing Bluegiga’s world-class integration services

and technical support, OEMs can be assured that their

products reach the market quickly and cost efficiently.
