gammu-smsd-files: gammu-smsd(1) backend using filesystem as a message storage


gammu-smsd-files - gammu-smsd(1) backend using filesystem as a message storage


gammu-smsd(1) supports several backends. Actual backend is chosen in a config file gammu-smsdrc(5).

FILES backend stores all data on a filesystem in folders defined by configuration (see gammu-smsdrc(5) for description of configuration options).


FILES backend does not support gammu-smsd-inject(1) program. This support might be eventually added in future versions.

Receiving of messages

Received messages are stored in a folder defined by configuration. The filename will be IN<date>_<time>_<serialno>_<phone_number>_<sequence>.<ext>, for example NN20021130_021531_00_+45409000931640979_00.txt.

Explanation of fields:

<date> - date in format YYYYMMDD
<time> - time in format HHMMSS
<serialno> - order of a message (in case more messages were received at same time), in format NN
<sequence> - part of the message for multipart messages, in format NN
<ext> - txt for text message, 8-bit messages are stored with bin extension

Transmitting of messages

Transmitted messages are read from a folder defined by configuration. The filename should be one of the following formats:

- OUT<phone_number>.<ext><options>
- OUT<priority>_<phone_number>_<serialno>.<ext><options>
- OUT<priority><date>_<time>_<serialno>_<phone_number>_<anything>.<ext><options>

Explanation of fields:

<priority> - an alphabetic character (A-Z) A = highest priority
<ext> - txt for normal text SMS
<options> - Options appended to the extension applying to text SMS:
 d - delivery report requested
 f - flash SMS
 b - WAP bookmark as name,URL

For example OUTG20040620_193810_123_+4512345678_xpq.txtdf is a flash text SMS requesting delivery reports.

Other fields are same as for received messages.

SMSes will be transmitted sequentially based on the file name. The contents of the file is the SMS to be transmitted (in Unicode or standard character set).

The contents of the file is the SMS to be transmitted (in Unicode or standard character set), for WAP bookmarks it is split on as Name,URL, for text messages whole file content is used.

Please note that if file is not in Unicode, encoding is detected based on locales, which do not have to be configured if SMSD is running from init script. If this is your case, please add locales definition to init script.
