I am trying to send SMS using gammu-smsd, but it does not work.

Modem: Huawei E1550

Steps:

#vi /etc/gammu-smsdrc

port= /dev/ttyUSB0
connection = at

Then restarted gammu-smsd:

# /etc/init.d/gammu-smsd restart

SMS Sending test 

echo "Test message" | gammu-smsd-inject TEXT 335123456

It does not send SMS.

Be sure gammu itself is reading from a right device path, and your user profile is in dialout group.

You may need to adjust bitrate to communicate to the module, so try to initiate direct communication using as example screen /dev/ttyUSB0 115200 and see what value fits at best.

The tool gammu-detect is also available, for spotting an initial configuration with a device, so man gammu-detect for more info.
