5 Software Features
5.1 Enhanced Easy GPRS Extension
5.1.1 Overview
The Easy GPRS feature allows the UC864 family module user to contact a device in
internet and establish with it a raw data flow over the WCDMA/EDGE/GPRS and
Internet networks.
This feature can be seen as a way to obtain a "virtual" serial connection between the
Application Software on the Internet machine involved and the controller of the Telit
UC864 family module, regardless of all the software stacks underlying.
An example of the protocol stack involved in the devices is reported:
This particular implementation allows to the devices interfacing to the Telit UC864
family
module the use of the WCDMA/EDGE/GPRS and Internet packet service
without the need to have an internal TCP/IP stack since this function is embedded
inside the module.
