GE863-GPS Software User Guide 1vv0300724 Rev. 2 - 24/01/07 1 Overview The purpose of this document is the description of some common AT command procedures that may be used with the Telit GE863-GPS module. In this document, all the basic functions of a mobile phone will be taken into account and for each one of them, a proper command sequence will be suggested. In the Advanced operation section the more useful services and features of the GSM network supported by the T

GE863-GPS Software User Guide 1vv0300724 Rev. 2 - 24/01/07 2.2 Command Response Timeout Every command issued to the Telit GE863-GPS returns a result response if response codes are enabled (default) (see command ATQn). The time needed to process the given command and return the response varies from command to command and may depend also from the network on which the command may interact. As a result every command is provided with a proper timeout time, if this time ela

A simple circuit to do it is: ON# Power ON impulse GND NOTE: don't use any pull up resistor on the ON# line. Using pull up resistor may bring to latch up problems on the GE863-GPS power regulator and improper power off of the module. The line ON# must be connected only in open co

Several things have to be checked in order to be sure that the device is ready to send and receive calls and SMS: 2.5.1 Autobauding At startup it is necessary to send an AT command to make the device set the right speed and character format of the serial port. When this is done the devic
