Device::Gsm::Pdu - library to manage PDU encoded data for GSM messaging
This is C<BETA> software, still needs extensive testing and
support for custom GSM commands, so use it at your own risk,
and without C<ANY> warranty! Have fun.
This module is meant to be used internally by C<Device::Gsm> class,
so you probably do not want to use it directly.
# DA is destination address
$DA = Device::Gsm::Pdu::encode_address(+39347101010);
$number = Device::Gsm::Pdu::decode_address( $DA );
# Encode 7 bit text to send messages
$text = Device::Gsm::Pdu::encode_text7(hello);
Device::Gsm::Pdu module includes a few basic functions to deal with SMS in PDU mode,
such as encoding GSM addresses (phone numbers) and, for now only, 7 bit text.
decode_address( pdu_encoded_address )
Takes a PDU encoded address and decodes into human-readable mobile number.
If number type is international, result will be prepended with a + sign.
Clearly, it is intended as an internal function.
print Device::Gsm::Pdu::decode_address( 0B919343171010F0 );
# prints `+39347101010;
encode_address( mobile_number )
Takes a mobile number and encodes it as DA (destination address).
If it begins with a +, as in +39328101010, it is treated as an international
print Device::Gsm::Pdu::encode_address( +39347101010 );
# prints `0B919343171010F0
encode_text7( text_string )
Encodes some text ASCII string in 7 bits PDU format, including a header byte
which tells the length is septets. This is the only 100% supported mode to
print Device::Gsm::Pdu::encode_text7( hellohello );
# prints `0AE832...
Converts a PDU (without the initial length octet) into a latin1 string.
my $pdu = CAFA9C0E0ABBDF7474590E8296E56C103A3C5E97E5;
# prints `Just another Perl hacker
Converts a text string in latin1 encoding (ISO-8859-1) into a PDU string.
my $text = "Just another Perl hacker";
# prints `CAFA9C0E0ABBDF7474590E8296E56C103A3C5E97E5
