System Requirements

1. Computer Hardware: At least one free Serial Port or Infrared Port or USB Port (with USB to Serial Converter) Note: For GSM Modems or GSM Phones connected using Infrared port or USB to Serial Converter, select appropriate virtual serial port to communicate with SMSLive.

2. GSM Modem With SIM Card SMSLive has been designed to work with any ETSI GSM 07.05 (Version 7.0.1 Release 1998) compatible GSM modem. Any GSM mobile phone (with suitable serial/USB data cable or Infrared port) that have built in modem and support AT commands can be used with SMSLive. Some of the popular GSM modems with which SMSLive has been tested are as follows: Falcom: Twist, Swift, Samba 55, Samba 75 iTegno: WM1080A, WM1080A1I, WM1080A1E, 3000, 3232E, 3232I, 3898 Multitech: MTCBA-G-UF1, MTCBA-G-UF2 Nokia: N30, N32, 6100, 6210, 6220, 6310, 6310i, 6820(Bluetooth), 8910 Siemens: TC35, TC35i, TC45, TC65, MC35, MC35i, MC45, MC55, MC65, MC75, A65, AC75, AC45, C35, C45, M35, M45, S35 SIMCOM: SIM100S, SIM100T Sony Ericsson: T310, T610, T630, T68, T68i, K310, K320, K500, K510, K600, K700, K750i, K800i, V800, W300, W550, W600, W700, W800i, W810, W900, Z1010, GC75, GC79, GC83, GC85, GC89 Teltonika: T-ModemUSB, T-ModemCOM Wavecom: Fastrack M1206B, Fastrack M1306B, Integra, WMOi3 A valid SIM card which has access to SMS service is required with the GSM modem. Note: Most Nokia phone models do not support AT command set directly. To use SMSLive with Nokia phones you may need to install Nokia Data Suite software or the appropriate modem driver driver (if using Infrared port) and select the virtual serial port for communication between SMSLive and Nokia handset.

Hardware Setup

Insert the SIM card into the slot provided in the GSM Modem/Phone. (Refer modem or phone manual for detail). Connect the modem/phone to the serial port of the computer using a suitable serial/USB data cable. If an Infrared port is used, then align the infrared port of the modem/phone to that of the computer. (refer your modem manual and computer hardware manual for more detail on using Infrared port). Switch ON the modem and check if the Modem/Phone starts up properly and registers in the network. Check by making a call from another phone if the GSM modem/phone is reachable. You can use the SMSLive Setting Screen to check if the computer and the modem are able to communicate with each other properly (Refer Frequently Asked Questions section in this reference manual) You can also use the SMSLive Setting Screen after completing Hardware and software setup on your computer to check the communication between the PC and GSM Modem/Phone. You can Also Try To Send Test message directly from the same screen Note: For GSM Modems or GSM Phones connected using Infrared port or USB to Serial Converter, select appropriate virtual serial port to communicate with SMSLive.

GSM Modems

SMSLive is designed to work with any GSM Modem that complies with ETSI specification GSM 07.05 and supports sending of text messages in PDU mode using AT Commands. There are a large number of good GSM Modems available in the market (e.g. Wavecom, Siemens, Ericsson, Falcom, Nokia etc) which can be used with SMSLive without any problems. GSM Phone handsets, that have a built in modem and supports AT Commands, can also be used with SMSLive, however, if the SMS application has to run for longer durations or the application has to send large number of messages then we recommend using GSM Modems because: GSM Phones normally run on battery power and no phone manufacturer recommends that the phone should be connected to battery charger continuously. GSM Phone handsets get heated up when they are used for sending large number of messages in sequence. GSM Modems normally run directly from power source and have a more robust design in terms of heat dissipation and heavy duty usage. Some GSM Phone handsets like Nokia do not support AT Commands directly and require the installation of Nokia Data Suite or the appropriate modem driver driver (if using Infrared port), which creates a virtual serial port.

How to troubleshoot if the GSM Modem is not communicating with your SMSLive application?

This can be done in following different ways: -Use the SMSLive demo application to check if it can read the modem parameters etc. -Use the Windows Hyperterminal to connect to the GSM Modem. Select the appropriate serial port and communication parameters (BaudRate, DataBits etc). Type the command 'AT' and hit enter key. The modem should respond back with 'OK' if the communication is correct. -Use SMSLive to see if there is any communication error with the GSM Modem.

Why do I get communication error although a GSM Modem/Phone is connected to the serial port?

This can happen due to many factors as given below: -Ensure that the modem power is switched ON. -The serial cable used to connect to the phone or modem is not proper. You can verify this by trying to connect to the modem using Windows Hyperterminal and sending AT command to the modem. The modem should respond with a OK Although most GSM modems and phones available in the market today have auto-bauding capability i.e. they can automatically adjust their baudrate but it is not the case with all GSM modems and phones. Therefore it is essential to match the baudrate setting of the GSM phone/modem and the baudrate setting of SMSLive . Communication errors will be triggered if the baudrate setting of the modem/phone is not same as the baudrate setting of SMSLive Try with different baudrates (and maybe different parity, databits and stopbits settings). -If you are connected using Infrared or Bluetooth, through virtual serial port, then ensure that the Infrared port or the Bluetooth device is enabled. Refer your computer hardware manual to know how to enable Infrared port or Bluetooth device feature in your computer. Also you must ensure that you have set the correct value for the Port property. Refer to virtual serial ports section for more details.

Can SMSLive be used with CDMA Modem?


How to troubleshoot if messages are not reaching the recipient?

If a message is not reaching its recipient, it could be because of many reasons. To diagnose the exact cause, do the following: -Check if the SIM card has sufficient credit for sending SMS. Check if you can send SMS manually using the same SIM on a GSM phone. -Check if the GSM network signal level available in the area where the modem is located, and is stable. -Check if you are able to send text messages using the SMSLive application (From Setting Screen). -Check if there is any error while sending the text message using SMSLive (Check Log Error).

Why do some characters get displayed as '?' (question mark) in the recipient's phone screen?

One of the following reasons can cause this problem: -If you use 7-bit default alphabet encoding and the text message contains characters that is not defined in 7-bit default alphabets, they will be replaced by '?' (question mark) symbol. -If you have used 8-bit character encoding and any of the character used in the message has a code that is more than 8-bits. -If you use 16-bit Unicode and the particular character codepage is not supported by the recipient's phone.
