GT863-PY Terminal Product Description 80269ST10026a Rev. 0 - 27/09/06 3 Software Features 3.1 Enhanced EASY GPRS Extension 3.1.1 Overview The EASY GPRS feature allows a user of the Telit GT863-PY to contact a device in the Internet and establish with it a raw data flow over the GPRS and Internet networks.
PAGE 26
GT863-PY Terminal Product Description 80269ST10026a Rev. 0 - 27/09/06 3.1.2 EASY GPRS definition The EASY GPRS feature provides a way to replace the need of an Internet TCP/IP stack at the terminal equipment side.
PAGE 27
GT863-PY Terminal Product Description 80269ST10026a Rev. 0 - 27/09/06 If a host nick name has been given then, while opening the connection in response to the AT#SKTOP command, the module will autonomously activate a GPRS connection and query its DNS to obtain the IP address relative to the host nick name provided. This process of context activation and DNS query may require a bit more time and requires that the GPRS network coverage is good enough to permit data transfers. 3.1.2.
PAGE 28
GT863-PY Terminal Product Description 80269ST10026a Rev. 0 - 27/09/06 All these steps are achieved through AT commands. As for common modem interface, two logical status are involved: command mode and data traffic mode. • In Command Mode (CM), some AT commands are provided to configure the Data Module Internet stack and to start up the data traffic.
PAGE 29
GT863-PY Terminal Product Description 80269ST10026a Rev. 0 - 27/09/06 • Note that activating a context implies getting an IP address from the network and this will be maintained throughout the session. The response code to the AT#GPRS=1 command reports the IP address obtained from the network, allowing the user to report it to his server or application. Deactivating the context implies freeing the network resources previously allocated to the device. 3.1.3.
