Sending SMS from device wired in the DB-9
connector
It allows external devices wired in the DB-9 connector (in RS-232 or
CAN-bus standard) to send SMS text messages.
The text format transmitted by the external device to 3G.next, through the
DB-9 connector in RS-232 standard, is required to be as follows:
SMSx…x:y…y<CTRL+Z>
Where:
SMS : string start
x…x : telephone number on which the SMS must be sent
y...y : message text to be sent (max. 160 characters)
<CTRL+Z> : non-editable character defining end of text.
The SMS can be sent on a 3G.next preset number (see “Setting telephone
number for notification service”). In this case, the text format is required
to be as follow:
SMS:y…y<CTRL+Z>
Note: to send SMS, 3G.next must be correctly registered to
the UMTS/GSM network and the SIM card must be
topped up. Moreover, 3G.next must not be engaged
with an ongoing voice call by the time the message
text is received from the external device.
Note: 3G.next does not send the external device any
notification of failed/successful SMS delivery. 3G.next
is capable of notifying the external device an SMS
feedback received by the remote recipient (see
“Sending received SMS text messages through DB-9
connector”).
Note: for CAN-bus communication please refer to
corresponding documentation.
