ZEUS Embedded Linux Development Kit Quickstart AEL Embedded Linux

Hardware and software requirements

• A ZEUS MODEM-1 board fitted with the GR64 Quad band GSM/GPRS module and

the supplied GSM antenna.

• A SIM card from a wireless service provider that offers GPRS connections.

• User name, password and Access Point Name (APN) for the GPRS service of the

wireless modem service provider (MSP).

This information is available on the internet or from the GPRS service

provider. For example, the details for T-Mobile (USA) and O2 (UK) are:

• username: {blank}; password: {blank}; APN: internet2.voicestream.com

• username: web; password: password; APN: mobile.o2.co.uk

There are many websites that provide the above MSP information on a

country-by-country basis. A list of the major providers is included on the

development kit CD (/examples/gprs-providers). Contact your service

provider if you are having difficulty locating the required information.

The following examples use the O2 UK MSP information

Software configuration

Follow these steps:

1 On the ZEUS AEL Embedded Linux CD you will find some useful scripts and

utilities that help turn the modem on and off. These are located in a package called

‘\packages\arcom-utils’. Copy the .deb install file to the ZEUS board and install it

using:

# dpkg –i modem-utils-zeus_1_arm.deb

Refer to the section

ZEUS Development Kit example programs on page 36, for

more information on what is contained in this package.

2 Check and edit the following files as necessary.

• /etc/ppp/peers/gprs

Change this to:

- Specify which serial port the GPRS module is connected to. (For the ZEUS,

this should be /dev/ttyS4.)

- Specify the baud rate of the serial port used for the wireless modem. (For

the ZEUS, this is typically 9600.)

- Specify the (MSP specific) user name in double quotes: user "web".
