Scenarios with GPRS Connection

The biggest challenges to the module performance are setting up a GPRS connection,
receiving data on javax.microedition.io interfaces and sending or receiving the data on the
RS232 API with the help of a Java application.
5.9.3.3.1

Upload

Since the TC65 supports GPRS class 12, up to four timeslots for upload data are available.
The Java application receives data over RS232 API and sends them over GPRS to a server.
