    ...
    @sms = $gsm->messages();

    if( @sms ) {
        foreach( @sms ) {
            print $msg->storage()   , "\n";
            print $msg->recipient() , "\n";
            print $msg->sender()    , "\n";
            print $msg->content()   , "\n";
            print $msg->time()      , "\n";

DESCRIPTION ^

Device::Gsm::Sms class implements very basic SMS message object, that can be used to decode +CMGL GSM command response to build a more friendly high-level object.

METHODS ^

The following is a list of methods applicable to Device::Gsm::Sms objects.

content()

See text() method.

decode()

Starts the decoding process of pdu binary data. If decoding process ends in success, return value is true and sms object is filled with all proper values.

If decoding process has errors or pdu data is not provided, return value is 0 (zero).

delete()

Delete the current SMS message from sim card. Example:

    $gsm = Device::Gsm->new();
    ...
    my @msg = $gsm->messages();
    $msg[0] && $msg[0]->delete();

new()

Basic constructor. You can build a new Device::Gsm::Sms object from the raw +CMGL header and PDU data. Those data is then decoded and a new sms object is instanced and all information filled, to be available for subsequent method calls.

The allowed parameters to new() method are:

header

This is the raw +CMGL header string as modem outputs when you issue a +CMGL command

pdu

Binary encoded sms data

storage

Tells which storage to delete the message from. Check the documentation of your phone to know valid storage values. Default values are:

ME

Deletes messages from gsm phone memory.

SC

Deletes messages from sim card.

index()

Returns the sms message index number, that is the position of message in the internal device memory or sim card. This number is used for example to delete the message.

    my $gsm = Device::Gsm->new(port=>'/dev/ttyS0');
    ...
    my @messages = $gsm->messages();
    ...
    # Delete the first returned message
    my $msg = shift @messages;
    $gsm->delete_sms( $msg->index() );

recipient()

Returns the sms recipient number (destination address = DA) as string (ex.: +39012345678).

sender()

Returns the sms sender number (originating address = OA) as string.

status()

Status of the message can be one value from the following list:

storage()

Returns the storage where SMS has been read from.

text()

Returns the textual content of sms message.

token()

Returns the given PDU token of the decoded message (internal usage).

type()

SMS messages can be of two types: SMS_SUBMIT and SMS_DELIVER, that are defined by two constants with those names. type() method returns one of these two values.

Example:

        if( $sms->type() == Device::Gsm::Sms::SMS_DELIVER ) {
                # ...
        }
        elsif( $sms->type() == Device::Gsm::Sms::SMS_SUBMIT ) {
                # ...
        }
