Bluegiga WT11 Class 1 Bluetoooth Module

Bluegiga WT11 BluetooothIn CISIUM one of our strategic markets is the Bluetooth communications. Bluetooth is intended for portable equipment and its applications. Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any setting and can also support fixed location applications such as smart energy functionality in the home (thermostats, etc.).

The Bluegiga WT11i is a fully integrated Bluetooth 2.1 + EDR, class 1 module combining antenna, Bluetooth radio and an on-board Bluetooth stack. The WT11i module utilizes Bluegiga's latest generation RF technology and provides better performance than Bluegiga's previous class 1 Bluetooth module WT11. For OEMs WT11i offers trouble free Bluetooth integration for applications where the best performance is needed and it is a drop-in performance upgrade for designs where WT11 is already used. WT11i comes with Bluegiga's iWRAP firmware offering the users simple software integration without the need of Bluetooth protocol or profile development.

One of the features we like of the WT11i is the powerful iWRAP4 Bluetooth stack firmware, it implements the full Bluetooth protocol stack and a set of Bluetooth profiles:

  • Serial Port Profile (SPP)
  • Hands Free Profile (HFP)
  • Headset Profile (HSP)
  • Object Push Profile (OPP)
  • File Transfer Profile (FTP)
  • Dial-up Networking Profile (DUN)
  • Human Interface Device (HID)
  • Advanced Audio Distrubution Profile (A2DP)
  • A/V Remote Control Profile (AVRCP)
  • Device Identification Profile (DI)
  • Health Device Profile (HDP)
  • Phone Book Access Profile (PBAP)
