Revision as of 10:25, 19 February 2014

This I/O Server provides services for sending and receiving SMSs and events generation for incoming calls via serial GSM modem.

The employed protocol complies with the AT commands set specified by the GSM standard set. It has been tested on the GenPro 16e and GenPro 18e modems by Erco&Gener and on the AirLink FXT009 modem by Sierra Wireless.

Communication

Employ a RS-232 straight cable to connect the modem directly to HSYCO or to an Ethernet/RS-232 gateway.

RS-232 parameters:

Baud rate 9600 (GenPro modems)
115200 (default on AirLink FXT009 modems)
Data bits 8
Stop bit 1
Parity none
Flow control RTS/CTS

HSYCO Configuration

Options

ID Default Values Description
pin <code> 4-digits PIN code of the SIM card (if used)
gui true true enable support for the UI object, UISET actions and USER commands
false disable UI support
inboxsize 10 n ≥ 0 the number of incoming messages to display in the UI object
countrycode <code> the default country code (e.g. “39”, for Italy) to be used when not otherwise specified. If omitted all provided numbers shall include the country code


srvc <number> phone number of the SMS service center (use the international format, e.g. +393492000200). If not specified, the default number saved on the SIM card will be used. If not available, the driver will not be able to sent SMS messages
resend 4 n ≥ 0 number of sending attempts on an outgoing SMS in case of error

Datapoints

ID Value R/W Description
connection online R connection established
offline R HSYCO can't connect to the modem
sms.<num> <text> R an SMS message has been received form the number <num>[Note 2] with <text> as body
W send an SMS message to the number <num>[Note 1] with <text> as body
call <num> R incoming call from number <num>[Note 2] in progress. An event is generated for each “ring” during the call
unknown R incoming call from an unknown number in progress
sms.<num>.sent <mr> R a message has been successfully sent to the number <num> and the message reference number is <mr>
sms.<num>.errors <val> R an error occurred while sending a message to number <num>. The value <val> is an increasing counter of the occurred errors since the I/O Server started
signal {0 ... 31} R the GSM signal level has the reported value (ranging from 0 to 31)
unknown R the GSM signal level is unknown

Note 1 
If the option 'countrycode' is used, then the country code will be automatically added to the specified numbers, unless the latter begins with a '+' character. For instance, assuming the option 'countrycode' is set to “39”, the addressee number “3480077000” will be automatically changed to “+393480077000”, while the number “+46765007700” will remain unchanged. If, on the other hand, no default country code has been specified, then the addressee numbers must always be provided prepending the country code.

Note 2 
The numbers are reported as sent from the modem and the format may vary depending on the number itself and the modem settings. If the reported number is an international number, then a '+' will be prepended to it, unless the country code is equal to the value of the 'countrycode' option. In the last case the country code will be omitted. In some cases, the sender number field might also be replaced by an alphanumeric string.

User Interface

SMS Object

The user interface for sending SMS messages:

UI Object sms.png

The SMS object is listed in the Project Editor’s new object list only when at least one GSM I/O Server is defined.


Parameters

  • server id: the server ID. Supports Redirect variables
  • position: the object's position. Use the pixels or rows and columns coordinates format

Syntax

(sms <server id>; <position>)

E.g.

(sms serverid; x10y20)

UISET Actions

To display the incoming SMS messages add a (text) object according the following table:

ID Attribute Set to
inbox value latest incoming SMS messages (as many as specified by the 'inboxsize' option)
connection.label.online visible true when datapoint connection = online
false when datapoint connection = offline
connection.label.offline visible true when datapoint connection = offline
false when datapoint connection = online
signal.label.0 visible true when the GSM signal level is equal to 0
false when the GSM signal level is not 0
signal.label.1 visible true when the GSM signal level is between 1 and 8
false when the GSM signal level is not between 1 and 8
signal.label.2 visible true when the GSM signal level is between 9 and 16
false when the GSM signal level is not between 9 and 16
signal.label.3 visible true when the GSM signal level is between 17 and 24
false when the GSM signal level is not between 17 and 24
signal.label.4 visible true when the GSM signal level is above 24
false when the GSM signal level is below 25
signal.label.unknown visible true when the GSM signal level is unknown
false when the GSM signal level is known
sending.label visible true when the modem is sending a message
false when the modem is not sending a message
error.label visible
blink
true for 5 seconds after there’s been an error sending a message
false default value

USER Commands

To send SMS messages via user interface, add the following UI objects in a container, setting their IDs as specified:

UI Object ID
input <ioserver_id>.sms.number
input <ioserver_id>.sms.text
submit <ioserver_id>.sms.send

From the resulting interface, digit the addressee number (or comma-separated list of numbers) in the input field with ID “<ioserver_id>.sms.number” and the body text in the input field “<ioserver_id>.sms.text”, then press the submit button.

N.B. If the option 'countrycode' is used, then the country code will be automatically added to the numbers, unless the latter begins with a '+'. For instance, assuming the value of the option 'countrycode' is set to “39”, the addressee number “3480077000” will be automatically changed to “+393480077000”, while the number “+46765007700” will remain unchanged. If, on the other hand, no default country code has been specified, then the addressee numbers must always be provided prepending the country code.

PUK-locked SIM

In case the SIM card used for the GSM modem is PUK-locked, it is required to provide the PUK code and a new PIN to set on the SIM card. To this end, create in the root folder of HSYCO a file named “<ioserver_id>.puk”, where <ioserver_id> is the ID of the corresponding I/O Server (e.g. “gsm.puk”). In this file add a single line containing the PUK code and the new PIN code separated by a comma, for instance:

12345678,1234

The file will be automatically deleted after it has been used by the I/O Server.
