Bluetooth Transmit Data Module
Shanghai Ehong Technologies Inc
Description:
3.0
module. It is a highly integrated and
sophisticated module which contains all
the necessary elements from radio to
antenna and a fully implemented
protocol stack. It is an ideal solution for
integrating Bluetooth® into various
products with limited knowledge of
Bluetooth® and RF technologies.
With AT command stack firmware,
designers can easily customize their
applications to support different
Bluetooth profiles, such as SPP, HID,
HFP and etc.
And the module can also interface with
Apple’s Authentication Coprocessor and
build an iAP over Bluetooth application.
Typical Bluetooth applications:
 Cable replacement
 Bar code and RFID scanners
 Measurement and monitoring
systems
 Industrial sensors and controls
 Medical devices
 Industrial PCs and laptops
