2.14.1 Reset signal

RESET is used to reset the GM862 modules. Whenever this signal is pulled low, the GM862 is reset. When the device is reset it stops any operation. After the release of the reset GM862-QUAD and GM862-QUAD-PY are unconditionally rebooted, while GM862-GPS is unconditionally shut down, without doing any detach operation from the network where it is registered to. This behaviour is not a proper shut down because any GSM device is requested to issue a detach request on turn off. For this reason the Reset signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response.

GM862 Product Description

80272ST10019a Rev. 10 – 18/09/2008

NOTE: do not use this signal to power off the GM862. Use the ON/OFF signal (Pin 17 of SO301) to perform this function or the AT#SHDN command.

3 Evaluation Kit

In order to assist you in the development of your Telit GM862 Family modules based application, Telit can supply an Evaluation Kit that interfaces the Telit GM862 Family modules directly with appropriate power supply, SIM card housing, RS 232 serial port level translator and USB, direct UART connection, Handset, Earphone and Hands-free (car kit) audio, antenna and all General Purpose I/O ports of Telit

GM862 Family modules suppported in a dedicated connector.

The EVK provides a fully functional solution for a complete data/phone application. The standard serial RS232 9 pin connector placed on the Evaluation Kit allows the connection of the EVK system with a PC or other DTE. The development of the applications utilizing the Telit GM862 Family modules must present a proper design of all the interfaces towards and from the module (e.g. power supply, audio paths, level translators), otherwise a decrease in the performances will be introduced or, in the worst case, a wrong design can even lead to an operating failure of the module.

In order to assist the hardware designer in his project phase, the EVK board presents a series of different solutions, which will cover the most common design requirements on the market, and which can be easily integrated in the OEM design as building blocks or can be taken as a starting points in developing a specific one. On the Board there are three different power supply inputs, that embrace a wide range of applications, from the automotive +12V / +24V nominal input to the stand alone battery powered device.

4 Software Features

4.1 Enhanced Easy GPRS Extension

4.1.1 Overview

The Easy GPRS feature allows the models Telit GM862-QUAD,QUAD-PY and GPS user to contact a device in internet and establish with it a raw data flow over the 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 GM862 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 GM862 module the use of the GPRS and Internet packet service without the need to have an internal TCP/IP stack since this function is embedded inside the module. The Easy GPRS overcomes some of the known limitations of the previous implementation and implements some new features such as:

• Keep the GPRS context active even after the closing of a socket, allowing the application to keep the same IP address;

• Also Mobile terminated (incoming) connections can be made, now it is possible to receive incoming TCP connection requests;

• A new internal firewall has been implemented in order to guarantee a certain level of security on internet applications.

4.1.2 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. The steps that will be required to obtain a virtual serial connection (that is actually a socket) to the Internet peer are:

• configuring the GPRS Access

• configuring the embedded TCP/IP stack behaviour

• defining the Internet Peer to be contacted

• request the GPRS and socket connections to be opened (host is connected)

• exchange raw data

• close the socket and GPRS context

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.

• In data traffic mode (Socket Mode, SKTM), the client can send/receive a raw data stream

which will be encapsulated in the previously configured TCP / IP packets which will be sent to the other side of the network and vice versa. Control plane of ongoing socket connection is deployed internally to the module.

For more detailed information regarding GPRS please consult Easy GPRS User Guide and AT Commands Reference Guide.

80272ST10019a Rev. 10 – 18/09/2008

4.2 Multisocket

New functionality of the Telit modules, multisocket is an extension of Telit Easy GPRS feature, which allows the user to have two contexts activated (that means two different IP address), more than one socket connection (with a maximum of 6) and simultaneous FTP client service.

The basic idea of multisocket is the possibility of suspend a socket connection with the escape sequence +++.

With IP Easy we can use a SKTD to open a socket connection and go online. After online activities we use +++ sequence to close the connection (see the figure below).

OOnnlliinnee mmooddee

DDaattaa TTrraaffffiicc

Where the green part represents the module command mode while the red part is the online mode.

Now, the online mode can be suspended with the escape sequence by using the multisocket feature. During suspend mode the data received by the socket will be buffered. These data will be displayed after socket resumption, as shown in the figure below:

This new feature allows the user to switch between online mode and command mode without closing the connection and eventually opening another socket (or resuming the suspended one) or FTP connection.

Another feature is the possibility to associate any socket connection to a specific context, this means that we can use different IP addresses for the connections (max 2). Socket identifier is called Connection Id (selects which socket we want to use from 1 up to 6) and every Connection Id is associated to a context.

4.3 Jammed Detect & Report Extension

4.3.1 Overview

The Jammed Detect & Report feature allows a Telit GM862-QUAD,QUAD-PY and GPS modules to detect the presence of a disturbing device such as a Communication Jammer and give indication to the user and/or send a report of that to the network.

This feature can be very important in alarm, security and safety applications that rely on the module for the communications. In these applications, the presence of a Jammer device can compromise the whole system reliability and functionality and therefore shall be recognized and reported either to the local system for countermeasure actions or to the network providing remote actions. An example scenario could be an intrusion detection system that uses the module for sending the alarm indication for example with an SMS to the system owner, and a thief incomes using a Jammer to prevent any communication between the GSM module and the network.

In such a case, the module detects the Jammer presence even before the break in and can trigger an alarm siren, other communication devices (PSTN modem) or directly report this condition to the network that can provide further security services for example sending SMS to the owner or police. Obviously this last service depends also from network infrastructure support and it may not be supported by some networks.

80272ST10019a Rev. 10 – 18/09/2008

4.4 CMUX

CMUX ( Converter-Multiplexer) is a multiplexing protocol implemented in the Telit module that can be used to send any data, SMS, fax, TCP data.

4.4.1.1 Product architecture

The Multiplexer mode enables one serial interface to transmit data to four different customer applications. This is achieved by providing four virtual channels using a Multiplexer (Mux).

This is especially advantageous when a fax/data/GPRS call is ongoing. Using the Multiplexer features, e.g. controlling the module or using the SMS service can be done via the additional channels without disturbing the data flow; access to the second UART is not necessary.

Furthermore, several accesses to the module can be created with the Multiplexer. This is of great advantage when several independent electronic devices or interfaces are used. To access the three virtual interfaces, both the GSM engine and the customer application must contain Mux components, which communicate over the multiplexer protocol.

In Multiplexer mode, AT commands and data are encapsulated into packets. Each packet has channel identification and may vary in length.

4.4.1.2 Implementation feature and limitation

• 7.10 CMUX Basic Option used

• CMUX implementation support four full DLCI (Serial Port)

• Every CMUX instance has its own user profile storage in NVM

• Independent setting of unsolicited message.

• In case of GPS product one serial port can be dedicated to NMEA output.

• Every CMUX instance has its own independent flow control

NOTE: More details about the Multiplexer mode are available in the Cmux Product Specification

4.5 Easy Script Extension - Python interpreter

4.5.1 Overview

NOTE: This feature is available only on models GM862-QUAD-PY and GM862-GPS.

The Easy Script Extension is a feature that allows driving the modem "internally", writing the controlling application directly in a nice high level language: Python. The Easy Script Extension is aimed at low complexity applications where the application was usually done by a small microcontroller that managed some I/O pins and the GM862-QUAD-PY and GM862GPS through the AT command interface.

4.5.3 Python implementation description

Python scripts are text files stored in NVM inside the Telit GM862-QUAD-PY and GM862-GPS. There's a file system inside the module that allows to write and read files with different names on one single level (no subdirectories are supported). Attention: it is possible to run only one Python script at the time.

The Python script is executed in a task inside the Telit module at the lowest priority, making sure this does not interfere with GSM/GPRS normal operations. This allows serial ports, protocol stack etc. to run independently from the Python script. The Python script interacts with the Telit module functionality through four build-in interfaces.

NOTE: Antenna GPS, GPS receiver and GPS Library are available exclusively for GPS module

GM862-GPS. Moreover SER2 Library can not be used by the GPS modules since their TRACE port is

not available.

• The MDM interface is the most important one. It allows Python script to send AT commands, receive responses and unsolicited indications, send data to the network and receive data from the network during connections. It is quite the same as the usual serial port interface in the

Telit module. The difference is that this interface is not a real serial port but just an internal

software bridge between Python and mobile internal AT command handling engine. All AT commands working in the Telit module are working in this software interface as well. Some of them have no meaning on this interface, such as those regarding serial port settings. The usual concept of flow control keeps its meaning over this interface, but it's managed internally.

• The MDM2 interface is the second interface between Python and mobile internal AT command handling. It is used to send AT commands from Python script to mobile and receive AT responses from mobile to Python script when the classic MDM built-in module already in use.

• The SER interface allows Python script to read from and write to the real physical serial port ASC0, that is usually used to send the AT commands to the module, for example to read information from external device. When Python is running this serial port is free to be used by Python script because it is not used as AT command interface since the AT parser is mapped into the internal virtual serial port. No flow control is available from Python on this port.

• The SER2 interface allows Python script to read from and write to the real physical serial port ASC1, that is usually available for trace and debug.

• The GPIO interface allows Python script to handle general purpose input output faster than through AT commands, skipping the command parser and going directly to control the pins.

• The MOD interface is a collection of useful functions.

• The IIC interface is an implementation on the Python core of the IIC bus Master. It allows

Python to create one or more IIC bus on the available GPIO pins.

• The SPI interface is an implementation on the Python core of the SPI bus Master. It allows Python to create one or more SPI bus on the available GPIO pins.

• The GPS interface is the interface between Python and mobile internal GPS controller. It is used in order to handle GPS controller without dedicated AT commands through MDM built-in module.

For the debug, the print command is directly forwarded on the EMMI TX pin (second serial port) at baud rate115200bps 8N1.
