GAMMU-SMSD-TABLES(7) Gammu GAMMU-SMSD-TABLES(7)

NAME

gammu-smsd-tables - description of tables for database backends of gammu-smsd(1)

The backends themselves are described in their sections, this document describes general database structure and required tables.

More SMS daemons can share single database. If you do not specify PhoneID in their configuration, all are treated equally and you have no guarantee which one sends outgoing message. If you configure PhoneID and use it when inserting message to the outbox table (gammu-smsd-inject does this), each SMS daemon will have separate outbox queue. See also smsd-multi.

RECEIVING OF MESSAGES

Received messages are stored in inbox table.

TRANSMITTING OF MESSAGES

Transmitted messages are read from table outbox and possible subsequent parts of the same message from outbox_multipart.

DESCRIPTION OF TABLES

EXAMPLES

Creating tables

SQL scripts to create all needed tables for most databases are included in Gammu documentation (docs/sql). As well as some PHP scripts interacting with the database.

For example to create SQLite tables, issue following command:

sqlite3 smsd.db < docs/sql/sqlite.sql


Injecting a message using SQL

To send a message, you can either use gammu-smsd-inject, which does all the magic for you, or you can insert the message manually. The simplest example is short text message:

INSERT INTO outbox (


    DestinationNumber,


    TextDecoded,


    CreatorID,


    Coding
) VALUES (


    '800123465',


    'This is a SQL test message',


    'Program',


    'Default_No_Compression'
);


Please note usage of TextDecoded field, for Text field, you would have to hex encode the unicode text:

INSERT INTO outbox (


    DestinationNumber,


    Text,


    CreatorID,


    Coding
) VALUES (


    '800123465',


    '005400680069007300200069007300200061002000530051004c002000740065007300740020006d006500730073006100670065',


    'Program',


    'Default_No_Compression'
);


Injecting long message using SQL

Inserting multipart messages is a bit more tricky, you need to construct also UDH header and store it hexadecimally written into UDH field. Unless you have a good reason to do this manually, use gammu-smsd-inject, C library (SMSD_InjectSMS()) or Python library (gammu.smsd.SMSD.InjectSMS()).

For long text message, the UDH starts with 050003 followed by byte as a message reference (you can put any hex value there, but it should be different for each message, D3 in following example), byte for number of messages (02 in example, it should be unique for each message you send to same phone number) and byte for number of current message (01 for first message, 02 for second, etc.).

I most cases, the mutlipart message has to be class 1.

For example long text message of two parts could look like following:

INSERT INTO outbox (


    CreatorID,


    MultiPart,


    DestinationNumber,


    UDH,


    TextDecoded,


    Coding,


    Class
) VALUES (


    'Gammu 1.23.91',


    'true',


    '123465',


    '050003D30201',


    'Mqukqirip ya konej eqniu rejropocejor hugiygydewl tfej nrupxujob xuemymiyliralj. Te tvyjuh qaxumur ibewfoiws zuucoz tdygu gelum L ejqigqesykl kya jdytbez',


    'Default_No_Compression',


    1
)
INSERT INTO outbox_multipart (


    SequencePosition,


    UDH,


    Class,


    TextDecoded,


    ID,


    Coding,


    Class
) VALUES (


    2,


    '050003D30202',


    'u xewz qisubevumxyzk ufuylehyzc. Nse xobq dfolizygqysj t bvowsyhyhyemim ovutpapeaempye giuuwbib.',


    <ID_OF_INSERTED_RECORD_IN_OUBOX_TABLE>,


    'Default_No_Compression',


    1
)


NOTE:

Adding UDH means that you have less space for text, in above example you can use only 153 characters in single message.
