An evaluation version of iWRAP firmware for Bluegiga’s WT11 and WT12 Bluetooth modules is available from Glyn High Tech Distribution. iWRAP 3.0 beta will introduce several additional functions such as Bluetooth HID and DI profiles and remote configuration over a Bluetooth link.

WT11 and WT12 are Class 1 and Class 2, next-generation, Bluetooth 2.0+EDR (enhanced data rate) modules. Both introduce three times faster data rates compared with existing Bluetooth 1.2 modules even with lower power consumption.

WT11 and WT12 are highly integrated modules, containing all the necessary elements from Bluetooth radio to antenna and a fully implemented protocol stack. WT11 and WT12 are suitable for developers who want to integrate Bluetooth wireless technology into their design with limited knowledge of Bluetooth and RF technologies.

iWRAP 3.0 will feature the following Bluetooth profiles: serial port; hands-free (v. 1.5) (HFP); hands-free audio gateway (v. 1.5); OBEX object push; human interface device (keyboard); device ID.

Other features include: over-the-air configuration; pairing with ‘PAIR {addr}’ command; piconet clock state reading with ‘CLOCK {link_id}’ command; enabling bypass UART enabling with iWRAP commands; remote device identification with ‘IDENT {addr}’ command.

HFP and HFP-AG profiles offer full-duplex GSM quality audio over a Bluetooth link plus call and SMS control with AT commands. The new profile support makes iWRAP suitable for all kinds of audio applications, such as motor vehicle audio systems, point-to-point audio applications, audio accessories and systems where simultaneous audio and data transfer are needed.
