3 Operation
To operate the device, you have to enter the PIN (
P
ersonal
I
dentification
N
umber) of the
inserted SIM card, as well as the APN (
A
ccess
P
oint
N
ame). The APN denotes the
destination of GPRS connections.
The PIN and the APN are not stored in the TAINY GMOD-T1. They must be entered
every time the GSM module or the complete device is switched on.
The PIN and APN can also be set via AT commands.
Controlling with
applications
Generally speaking, the application or application program that you
execute on the connected computer will control the device. This
means that the commands for the establishment and closure of a
data or voice connection via GSM or GPRS network are issued to
the device by the application. To do so, the application
communicates with the device via AT commands as with any other
modem. You will find a list of all supported AT commands in the
PDF file
AT Command Set
on the CD supplied.
The various functions of the device are not necessarily all operated
by the application used. Therefore please note the following points:
•
Switching the device on/off- see page 12.
•
Switching off the GSM engine – see page 12.
•
The PIN and APN must be entered every time the device is
switched on.
•
Connections for which the PPP Protocol is used, e.g. GPRS
connections to the Internet, may have to be initiated manually -
see page 25.
Controlling direct
with AT
commands
You can also make the device perform the required functions by
giving it direct AT commands. In this case, you can use any
terminal program to enter the AT commands. (See
Working with a
terminal program
, page 26.)
Or you can program your own communication program designed
specifically to suit your purposes.
You will find a list of AT commands in the PDF file
AT Command Set
on the CD supplied. (Please not that voice
functionality is not supported).
Enter PIN first
Please enter the PIN first before any other AT commands. Until a
PIN has been entered most AT commands will be answered with
ERROR.
