WT11i Bluetooth® Module
DESCRIPTION
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 its
predecessor WT11. For OEM's WT11i offers trouble
free Bluetooth integration for applications where the
best performance is needed and it’s 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.
APPLICATIONS:
Hand held terminals
Industrial devices
Point-of-Sale systems
PCs
Personal Digital Assistants (PDAs)
Computer Accessories
Access Points
Automotive Diagnostics Units
