3.2.6 SMS Direct

A major benefit of GSM technology is that it supports short messages (SMS) for easy communication over the mobile
network. Robustel’s proprietary SMS Direct allows you to expand your applications and reduce cost. For example,
SMS Direct can be used to update the message on a highway display panel, place refill orders for vending machines,
handle maintenance for remote rental equipment, or even help create an SMS alarm by directly transforming text,
binary, or unicode data from a legacy device to short messages, but without using AT Commands. SMS Direct is
particularly suitable for devices that communicate infrequently, or lack access to the local network. SMS Direct

Robustel GoRugged M1000 User Guide

RT_UG_M1000 Standard_v.2.0.0 20.12.2013 27 / 83

converts ASCII and binary data to short message transparently (both back and forth). In addition, a caller ID (phone
number) identification can be used to block the message sent from the uncertified users, broadcast messages, and
unwanted SMS advertisements.
Robustel’s proprietary SMS Direct has the following features:

1. Transparently converts serial data to short message or vise versa without using AT Commands.

2. Text, binary, and Unicode formats are supported.

3. Verification of Incoming Caller ID is implemented to block uncertified users.

4. The configuration profile can be easily stored, and then copied to other modems.

The follow table introduces the SMS Direct function.

The Packet length setting refers to the maximum amount of data that is allowed to
accumulate in the serial port buffer before sending. At the default of 0 for packet length,
no maximum amount is specified and data in the buffer will be sent as specified by the
interval timeout or delimiter settings. When a packet length between 1 and 140/160
bytes is specified, data in the buffer will be sent as soon it reaches the specified length.
0 is no limitation.

4.1 AT Command Set (Only Available under Normal Mode)

The modem supports the guidelines known as the “AT Command Set.” The AT Command Set is the industry standard
line-oriented command language used to communicate with the modem.

Note: AT Commands may be entered from terminal software such as Robustel Modem Configurator’s Debug Tab or
Windows HyperTerminal.

4.1.1 Starting Robustel Modem Configurator

Please refer to Debug (Only Available under “Normal Mode”) and find out how to send AT Commands by the Modem
Configurator.

4.1.2 Starting Windows Hyper Terminal

User could also control modem via AT Commands by Windows Hyper Terminal.

1. Go to “Windows Start->All Programms->Accessories-Communications>HyperTerminal” and click to open.

2. Establish a new connection and input the connection name.

4.2 GSM CSD Connection (Only Available under Normal Mode)

4.2.1 Overview

A Circuit-Switched Data Connection makes the wireless modem work in a manner similar to a regular analog modem.
CSD (Circuit Switched Data) is the original form of data transmission developed for GSM systems. By using a single
radio time slot, CSD is able to deliver 9.6 to 14.4 kbit/s data transmission to both the GSM Network and PSTN
Switching Subsystem through direct calls. Most of the time, it is initiated by standard AT commands. Using the
modem to access remote devices by CSD is often more convenient than installing cables and data lines. Data
collection and monitoring will be more flexible since CSD can be used for applications that are hard to wire or hard
to access.

Note: Ensure that your SIM card has the CSD Service activated. For most regions, you must apply to your mobile
service provider to receive this service.

4.2.2 Establishing a CSD Connection

1. Enable CSD at Basic Tab under Normal Mode;

2. Start Modem Configurator and click the Debug tab under Config Mode, with the current communication

parameters (default: 115200 bps, 8 for Data bits, None for Parity, 1 for Stop bits, and None for flow control).

3. Type ATD <phone number> and click Send to establish a CSD connection. (e.g. ATD 123456, in which 123456 is

the phone number.)

4. After remote side answering the CSD call, then the CSD connection has been established successfully, and you

can switch to data mode to proceed with data communication.

Confidential

5. To disconnect the connection, type +++ in Send windows and enable Enter, then click Send. The modem will

respond with OK to indicate that you have already switched back to the command mode.

6. Type ATH and then press Enter to disconnect.

Robustel GoRugged M1000 User Guide

RT_UG_M1000 Standard_v.2.0.0 20.12.2013 53 / 83
Confidential

Note:

1. +++ is the escape sequence, and ATH is the hang-up command.

2. For international calls, the local international prefix does not need to be set, but does need to be replaced by the

+ character. E.g., you would type ATD+86123456, in which +86 is the country code.

3. User could also establish a CSD connection by using terminal software such as Windows HyperTerminal, or

Robustel Modem Configurator’s Debug Tab.

4.2.3 Answering a CSD Connection

1. To answer a call manually, when the Modem Configurator displays the RING response, type to answer a call

manually, when the Modem Configurator displays the RING response, type ATA , enable Enter and click Send.

2. After the CSD connection has been established, and the modem will be in the data mode. At this point you can

proceed with data communication.

3. To answer a call automatically, type ATS0=x and click Send, and then type AT&W and click Send in the Modem

Configurator. In this case, replace x with the number of rings that the modem receive before answering the call.

Robustel GoRugged M1000 User Guide

RT_UG_M1000 Standard_v.2.0.0 20.12.2013 54 / 83
Confidential

Note:

1. ATA is the Answer command. ATS0=<x> is the auto-answer command. The AT&W command helps to save the

current settings to the modem.

2. It is much easier to activate Auto-answer using Modem Configurator. Input the number of rings to wait in the

input box and then click Rings Auto-answer.

3. To disconnect the modem, type +++. The modem will respond with OK, which means that you have already

switched back to command mode.

4. Type ATH and press Enter to disconnect.

4.3 Using Short Message Service by Using AT Commands (Only Available

under Normal Mode)

GSM technology offers the benefit of using SMS (short message service) as an easy way to communicate over the
mobile network.
The following topics are covered in this chapter:

1. Sending a Short Message

2. Reading a Short Message

3. Deleting a Short Message

Note: Please enable the following option under Config Mode, then switch back to Normal Mode.

4.3.1 Sending a Short Message

1. Type AT+CMGF=1 and then click Send.

2. Type AT+CMGS=”<phone number>” and then click Send. The terminal will automatically move to the next line,

which starts with >. Type your message to the right of the >.

3. Enable Ctrl + Z and click Send to deliver the message.

Note: AT+CMGF=1 sets the SMS to Text mode.

4.3.2 Reading a Short Message

1. Type AT+CMGF=1 and then press Enter.

2. Type AT+CNMI=2,1 and then press Enter.

3. When a short message is received, the modem will show the storage number of the message after “+CMIT: “SM”,

x” (where the x is the storage number).

4. Type AT+CMGR=x to read the message.

5. In the example shown below, the x=5 means that the message is stored in the 5th storage location.

4.5 GPRS Connection (Only Available under Normal Mode)

4.5.1 Overview

GPRS is a packet-switched technology, which means that multiple users share the same transmission channel. In
addition, GPRS transmits only when there is outgoing data. This means that the available bandwidth can be
dedicated solely to data communication when needed. In general, a GPRS network can be viewed as a special IP
network that offers IP connectivity to IP terminals. Devices such as PCs, embedded computers, and PLCs that are
PPP-enabled can be easily connected to the IP network and the Internet.

The modem provides multi-slot Class 10, which means that there are 4 Rx timeslots plus 1 Tx timeslot, or 3 Rx
timeslots plus 2 Tx timeslot. The CS-1 to CS-4 Coding Schemes must be supported by the provider. GPRS offers no
guaranteed data rates or bandwidth. The value assigned by the provider (coding scheme and timeslots) can change
dynamically during a connection.
In general, for the 1 Tx + 4 Rx combination, the Tx throughput is around 8-12 Kbps when the Rx throughput is
around 32-48 Kbps.
For the 2 Tx + 3 Rx combination, the Tx throughput is around 16-24 Kbps when the Rx throughput is around 24-36
Kbps.

4.5.2 Windows GPRS Access

The modem can use Windows DUN (Dial-up Networking) to provide the Internet access through the GPRS mobile
network. Instructions are described in the following chapters.

Note: The specific steps may vary depending on your version of Windows and your Windows settings.

Set Modem Baud Rate to 19200 bps under Normal Mode

1. Select 19200 bps, and then click “Change Baudrate to”;

2. Exit the Modem Configurator.

When there is a password, SMS command has following structure: Password:cmd1;cmd2;cmd3;…;cmdn

 Cmd1, cmd2, cmd3 to Cmdn, which are command identification number 0000 – 9999
 A, b, c to n, which are command parameters
 The semicolon character (‘;’) is used to separate more than one commands packed in a single SMS.

5.3.2 SMS Control Steps

1. Use command Password:cmd1;cmd2;cmd3;…;cmdn or cmd1;cmd2;cmd3;…;cmdn to set new parameters.

2. After setting new parameters for M1000, remember to use 0004 command to save parameters and reset the

modem, then the new parameters will take effect.

3. In one SMS, if there is more than two cmd, remember to use punctuation “;” to divide each cmd.

Note: E.g., 1234:1001,M1000;0004
In this command, password is 1234, 1001 is the cmd to set device’s name, “M1000” is M1000’s name that we want to
set, then save parameters and reset the modem to take effect with command 0004.

5.5 GSM Alphabet

Standard SMS can contain 160 characters. However, the characters typed must be part of the so-called 7-bit default
alphabet as specified by GSM 3.38. You can see in the table below that this alphabet contains all ASCII characters and
some accented characters.
For example, u umlaut (ü) and e with grave (è), are in this set. Please study the table below to have a complete
overview. Using any character not in this set, will make the SMS a Unicode SMS and limit the length of the SMS to 70
characters.
Note: a few characters actually count as two characters. These characters are:
{}[]~|\ and the Euro symbol: €
You can also see that in the table below in the hex column. These characters need to be escaped.
Below is the 7 bit default alphabet as specified by GSM 03.38. The corresponding ISO-8859-1 decimal codes are
shown in the rightmost column. Note that the euro sign (€) is also included.
