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.

Installation Guide: Connect the modem and then check if it is recognized as tty:

ls /dev/tty* | grep USB

Then give required permissions:

chmod 777 /dev/ttyUSB0

Install gammu:

apt-get install gammu

Config gammu:

gammu-config

Check the status:

screen /dev/ttyUSB0 115200

add user to dialout (Maybe you won't need this but i tried this too):

adduser user dialout

Install gammu-smsd:

apt-get install gammu-smsd

check the configuration file gammu-smsd:

nano /etc/gammu-smsdrc

Restart gammu-smsd:

/etc/init.d/gammu-smsd restart

Use gammu automatic detection:

gammu-detect

configur gammu:

mkdir -p /var/log/gammu /var/spool/gammu/{inbox,outbox,sent,error}
chown user:user -R /var/spool/gammu/*
chmod 777 -R /var/spool/gammu/*
wget -c https://raw.githubusercontent.com/antonraharja/playSMS/master/contrib/gammu/linux/gammu-smsdrc
cp gammu-smsdrc /etc/

gammu-smsdrc configs:

nano /etc/gammu-smsdrc
