2.13.1 Reset signal

Signal Function I/O GE864 ball GC864 pin

RESET Phone reset I/O A2 54

RESET is used to reset the GE864 and GC864. Whenever this signal is pulled low, the GE864 / GC864

is reset. When the device is reset it stops any operation and after the release of the reset it shuts down, without doing any detach operation from the network where it is registered to. This behavior 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.

The RESET is internally controlled on start-up to achieve always a proper power-on reset sequence, so there's no need to control this pin on start-up. It may only be used to reset a device

already on that is not responding to any command.

NOTE: do not use this signal to power off the Telit GE864 / GC864 module. Use the ON_OFF* signal to perform this function or the AT#SHDN command.

Reset Signal Operating levels:

Signal Min Max

RESET Input high 2.2V* 3.3V

RESET Input low 0V 0.2V

* this signal is internally pulled up so the pin can be left floating if not used.

If unused, this signal may be left unconnected. If used, then it must always be connected with an open collector transistor, to allow to the internal circuitry the power on reset and under voltage

lockout functions.

2.14 RTC Bypass out

The VRTC signal brings out the Real Time Clock supply which is separate from the rest of the digital part, allowing having only RTC going on when all the other parts of the device are off. To this power output a backup capacitor can be added in order to increase the RTC autonomy during power off of the battery. NO Devices must be powered from this pin.

2.15 VAUX power output

A regulated power supply output is provided in order to supply small devices from module. This output is active when the module is ON and goes off when module is shut down. The operating range characteristics of the supply are:

2.16 Audio levels specifications

The audio of the GE864 / GC864 is organized into two main paths:

- internal path (called also MT)

- external path (called also HF)

These two paths are meant respectively for handset and headset/hands-free use. The GE864 /

GC864 has a built in echo canceller and a noise suppressor, tuned separately for the two audio

paths; for the internal path the echo canceller parameters are suited to cancel the echo generated by a handset, while for the external audio path they are suited for a hands-free use. For more information on the audio refer to the Hardware User Guide. The following table reports all the audio level specifications.

2.17 Camera compatibility (EASY CAMERA)

The GE864 / GC864 provides a direct support for the camera whose characteristics are the following:

Model: TRANSCHIP TC5747 Technology: CMOS COLOR camera Max picture size: VGA 640x480 pixels Output format: JPEG Sensitivity: 4V/lux-sec (including gain)

The camera will be directly managed by the hardware/software with some interface circuitry, providing a custom AT command interface to operate with it.

The camera interface requires the pins and GPIOs:

Signal GE864 ball GC864 pin

CAM_SDA D7 36 CAM_SCL C6 35 CAM_CLK F8 44 CAM_ON K11 67 CAM_RST C9 76

When the camera is activated, then these pins are not accessible as GPIO. The AT commands of the module allows to take a snapshot and successively download it through the serial line in various formats.

2.18 Converters

2.18.1 ADC Converter

The on board A/D are 11-bit converter. They are able to read a voltage level in the range of 0÷2 volts applied on the ADC pin input, store and convert it into 11 bit word.

Input Voltage range 0 2 Volt AD conversion - 11 bits Resolution - < 1 mV Sampling rate 1 (idle) 60 (on traffic) secs

2.18.2 DAC Converter

The on board DAC is a 10 bit converter, able to generate a analogue value based a specific input in the range from 0 up to 1023. However, an external low-pass filter is necessary. See the HW User Guide for the details.

3 Evaluation Kit

In order to assist you in the development of your Telit GE864 / GC864 module based application, Telit can supply the EVK2 Evaluation Kit with appropriate power supply, SIM card housing, RS 232 serial

port level translator, direct UART connection, Handset, Headset and Hands-free (car kit) audio, antenna.

The EVK2 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

EVK2 system with a PC or other DTE.

The development of the applications utilizing the Telit GE864 / GC864 module 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 EVK2 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 starting points to develop a specific one.

GE864 / GC864 Hardware User Guide.

3.1.1 Power Supply

In the Board there are three different power sources, that embrace a wide range of applications, from the automotive +12V input to the stand alone battery powered device. The power sources nominal input voltages are:

• +12V input (typically automotive)

• +5V input (typically embedded systems)

• +3.8V input (Li-Ion Battery)

Each one of these power sources can supply the Telit GE864 / GC864 module and the whole circuitry embodied in the Evaluation Kit.

Only one of these power sources can be used at a time and it is selectable with two jumpers. For the battery power supply a Li-Ion battery charger circuit is provided.

3.1.2 Serial interface

The communications between your application and the Telit GE864 / GC864 module must be done

through a serial interface which can be a standard CMOS UART or a RS232 port. All levels of the RS232 port are conforming to RS232 and V.24 standard and a PC serial port can be directly connected to this connector. Both these interfaces are supported.

3.1.3 Audio

The Evaluation Kit board provides two software/hardware selectable audio paths, the internal and the

external one. All the handset, headset and hands free-car kit functions are supported. Furthermore for each audio path two solutions are presented: single ended and balanced

3.1.4 GPIO and Leds

5 Software Features

5.1 Enhanced Easy GPRS Extension

5.1.1 Overview

The Easy GPRS feature allows the Telit GE864 / GC864 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 GE864 / GC864 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 GE864 / GC864 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 new Enhanced version of 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.

80273ST10008A Rev. 3 - 10/02/06

5.1.2 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:

a) configuring the GPRS Access b) configuring the embedded TCP/IP stack behavior c) defining the Internet Peer to be contacted d) request the GPRS and socket connections to be opened (host is connected) e) exchange raw data f) 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.

5.1.2.1 Configuring the GPRS access

The GPRS access configuration is done by setting:

- the GPRS context number 1 parameters (see +CGDCONT command)

- the Authentication parameters: User Name and Password (see commands #USERID, #PASSW)

5.1.2.2 Configuring the embedded TCP/IP stack

The TCP/IP stack behavior must be configured by setting:

- the packet default size (see command #PKTSZ)

- the data sending timeout (see command #DSTO)

- the socket inactivity timeout (see command #SKTTO)

5.1.2.3 Defining the Internet peer to be contacted

As last setting definition, the host to be contacted and on which port/protocol must be set:

- the socket definition (see command #SKTSET)

Telit GE864 and GC864

Product Description

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.

80273ST10008A Rev. 3 - 10/02/06

5.1.2.4 Open the connection with the internet host

With the AT#SKTOP all the process required to connect with the internet host starts:

- GE864 / GC864 activates the first context

- GE864 / GC864 proceeds to the authentication with the parameters specified

- Eventually does the DNS query to resolve the IP address of the host name internet peer

- GE864 / GC864 establishes a TCP/UDP (depending on the parameter request) connection with the given internet host

- Once the connection is up the module reports the code: CONNECT

From this moment the data incoming in the serial port is packet and sent to the Internet host, while the data received from the host is buffered and flushed to the Terminal Equipment.

5.1.2.5 Close the Socket and deactivate the context

The connection can be closed because of:

- remote host TCP connection close

- socket inactivity timeout

- Terminal Equipment by issuing the escape sequence "+++"

- Network deactivation

: if in the raw data to be sent there's an escape sequence, then the TE must work it out and

Note sent it in a different fashion to guarantee that the connection is not closed. The pause time is defined in the parameter S12. On the reception of an escape sequence the GE864 / GC864 closes the connection, deactivates the GPRS context returning to command mode and issuing the NO CARRIER code.

5.1.3 Enhanced Easy GPRS Outgoing connection

The New Enhanced Easy GPRS feature provides a way to place outgoing TCP/UDP connections and keep the same IP address after a connection, leaving the GPRS context active. The steps that will be required open a socket and close it without closing the GRPS context are:

g) configuring the GPRS Access h) configuring the embedded TCP/IP stack behavior i) defining the Internet Peer to be contacted j) request the GPRS context to be activated k) request the socket connection to be opened l) exchange data m) close the TCP connection while keeping the GPRS active

All these steps are achieved through AT commands. As for common modem interface, two logical statuses are involved: command mode and data traffic mode.

Telit GE864 and GC864

Product Description

80273ST10008A Rev. 3 - 10/02/06

- In Command Mode (CM), some AT commands are provided to configure the Data Module Internet stack and to start up the data traffic.

5.1.3.1 Configuring the GPRS access

The GPRS access configuration is done by setting:

- the GPRS context number 1 parameters (see +CGDCONT command)

- the Authentication parameters: User Name and Password (see commands #USERID, #PASSW)

5.1.3.2 Configuring the embedded TCP/IP stack

The TCP/IP stack behavior must be configured by setting:

- the packet default size (see command #PKTSZ)

- the data sending timeout (see command #DSTO)

- the socket inactivity timeout (see command #SKTTO)

5.1.3.3 Defining the Internet peer to be contacted

As last setting definition, the host to be contacted and on which port/protocol must be set:

- the socket definition (see command #SKTSET)

This command permits also to specify the host name instead of its IP address, if a host name is given to the set command, then the module stores it as a host nick name. It is care of the module user to guarantee that the host nick name provided corresponds to an existing internet peer. If an 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. Note that this setting command is not needed if the new #SKTD command is used.

5.1.3.4 Request the GPRS context to be activated

With the new command #GPRS you can activate or deactivate a GPRS context INDEPENDENTLY from the TCP socket opening:

AT#GPRS=1 activates the context, AT#GPRS=0 deactivates the context

Therefore with the AT#GPRS=1 command the module

- GE864 / GC864 activates the context previously defined with AT+CGDCONT

- GE864 / GC864 proceeds to the authentication with the parameters specified

Telit GE864 and GC864

Product Description

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.

80273ST10008A Rev. 3 - 10/02/06

5.1.3.5 Open the connection with the internet host

With the new command #SKTD (socket Dial) the TCP/UDP request to connect with the internet host starts:

- Eventually does the DNS query to resolve the IP address of the host name internet peer

- GE864 / GC864 establishes a TCP/UDP (depending on the parameter request) connection with the given internet host

- Once the connection is up the module reports the code: CONNECT

Note that the peer specifications of this socket Dial are within the command and not the one stored with #SKTSET command. From this moment the data incoming in the serial port is packet and sent to the Internet host, while the data received from the host is serialised and flushed to the Terminal Equipment.

NOTE: this command differently from the AT#SKTOP DOES NOT automate all the process of activating the GPRS, if no GPRS is active the command reports ERROR; therefore before issuing this command the GPRS shall be activated with AT#GPRS=1 command. In the same manner, when disconnecting the #SKTD command does not close the GPRS context, leaving it active for next connections until an AT#GPRS=0 command is issued or the network requests a context closing.

5.1.3.6 Close the Socket without deactivating the context

The connection can be closed because of:

- remote host TCP connection close

- socket inactivity timeout

- Terminal Equipment by issuing the escape sequence "+++"

- Network deactivation

Note: if in the raw data to be sent there's an escape sequence, then the TE must work it out and sent it in a different fashion to guarantee that the connection is not closed. The pause time is defined in the parameter S12. On the reception of an escape sequence if the socket was opened with the AT#SKTD command, the GE864 / GC864 closes the connection, does not deactivate the GPRS context and returns to command mode issuing the NO CARRIER code.

5.1.4 Enhanced Easy GPRS Incoming Connection

The New Enhanced Easy GPRS feature provides a way to accept incoming TCP/UDP connections and keep the same IP address after a connection, leaving the GPRS context active.

Telit GE864 and GC864

Product Description

The steps that will be required to open a socket in listen, waiting for connection requests from remote hosts and accept these request connections only from a selected set of hosts, then close it without closing the GRPS context are:

a) Configuring the GPRS Access b) Configuring the embedded TCP/IP stack behavior (see par. c) Defining the Internet Peer that can contact this device (firewall settings) (see par. d) Requesting the GPRS context to be activated (see par. e) Request the socket connection to be opened in listen (see par. f) Receive connection requests (see par. g) exchange data h) Close the TCP connection while keeping the GPRS active (see par.

All these steps are achieved through AT commands. As for common modem interface, two logical statuses 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.

5.1.4.1 Defining the Internet Peer that can contact this device (firewall settings)

The GE864 / GC864 have an internal Firewall that controls the behavior of the incoming connections to the module. The firewall applies for INCOMING (listening) connections; OUTGOING connections will be always done regardless of the firewall settings. Firewall General policy is DROP, therefore all packets that are not included into an ACCEPT chain rule will be silently discarded.

When a packet incomes from the IP address <incoming IP>, the firewall chain rules will be scanned for matching with the following criteria:

<incoming IP> & <net mask> = <ip_address> ?

if the result is yes, then the packet is accepted and the rule scan is finished, otherwise the next chain is taken into account until the end of the rules when the packet is silently dropped if no matching was found.

For example, let assume we want to accept connections only from our devices which are on the IP addresses ranging from:

197.158.1.1 to 197.158.255.255

We need to add the following chain to the firewall:

AT#FRWL=1,"197.158.1.1","255.255.0.0"

80273ST10008A Rev. 3 - 10/02/06

5.1.4.2 Request the socket connection to be opened in listen

With the new command #SKTL (socket Listen) the TCP request to start listening for connection requests is executed:

- GE864 / GC864 opens a listening socket on the port specified, waiting for incoming TCP

connections (depending on the parameter request) with the internet hosts

The parameters that shall be specified are the local port where packets shall be received, the type of socket and the closing behavior.

5.1.4.3 Receiving connection requests

Once the connection request is received, the module reports an indication of connection with an unsolicited code +CONN FROM: <remote address>

- then connection is accepted and once it is up the module reports the code:

CONNECT

From this moment the data incoming in the serial port is packet and sent to the Internet host, while the data received from the host is serialised and flushed to the Terminal Equipment. Note that the connections request are FIRST screened in the firewall, then if they are accepted they pass to the listening socket; therefore only hosts that are in the ACCEPT chain rules of the firewall can induce a connection request, the other host requests will be silently discarded without any indication to the remote host (for security reasons). Once the connection is received and closed, the socket is not anymore in listen. If the application needs again to be in listen, then it shall send again the socket listen #SKTL command.

NOTE: this command differently from the AT#SKTOP DOES NOT automate all the process of activating the GPRS, if no GPRS is active the command reports ERROR; therefore before issuing this command the GPRS shall be activated with AT#GPRS=1 command. In the same manner, when disconnecting the #SKTL command does not close the GPRS context, leaving it active for next connections until an AT#GPRS=0 command is issued or the network requests a context closing.

5.1.4.4 Known limitations

The implementation of the EASY GPRS feature has the following known limitations:

- Only one socket can be opened at a time, no multiple socket connections can be made;

- Only one connection request can be accepted at a time, subsequent requests will be silently

discarded.

- Only the first GPRS context is associated with this feature;

- It is taken for granted that external processor will be able to handle at least a limited v.24

implementation: RTS, CTS and, highly recommended, DCD lines; this because software flow control is not applicable to the feature;

- Due to the particularity of this feature, the flow control of both the directions uplink and

downlink is interlocked

5.2 Jammed Detect & Report Extension

5.2.1 Overview

The Jammed Detect & Report feature allows a Telit GE864 / GC864 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 income 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.

5.3.3 Python implementation description

Python scripts are text files; it is possible to run one Python script in the Telit GE864-PY / GC864PY.

The Python script is stored in NVM memory inside the module. Moreover, there is a file system inside the module that allows to write and read files with different names on one single level (no subdirectories are supported). The Python script is executed in a task inside the Telit GE864 / GC864 at the lowest priority, making sure this does not interfere with GPRS/GSM normal operations. This allows serial ports, protocol stack etc. to run independently from the Python script. The Python script interacts with the Telit GE864 / GC864 functionality through four build-in interfaces.

Telit GE864 and GC864

Product Description

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 GE864 / GC864. 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 GE864 / GC864 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 SER interface allows Python script to read from and write to the REAL, physical serial port where usually the AT command interface resides, for example to read NMEA information from a GPS 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 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. For the debug, the print command is directly forwarded on the EMMI TX pin (second serial port) at 9600 baud 8N1.
