How to install smstools on Raspberry PI with a nn dongle
========================================================


Get deviceid for the dongle
---------------------------

    sudo lsusb

I get the result...

    Bus 001 Device 005: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800/E173 (HSPA modem)



Make sure the dongle is detected
--------------------------------
The dongle in question have 2 different "modes".
One, default, which emulates a cdrom

  sudo apt-get install usb-modeswitch usb-modeswitch-data
  cd /usr/share/usb_modeswitch
  sudo tar -zxvf configPack.tar.gz
  sudo cp 12d1\:1446 /etc/usb_modeswitch.d/
  sudo /etc/init.d/udev restart
  
Ofcourse you should replace the source file with your device id.

Now unplug and plug your dongle and check some dmsg messages.

    dmsg
Towards the end of the output something similar to this should turn up if it works.

You should get some ttyUSBx devices for the modem in the dongle... yay!


Install and configure smstools
------------------------------

    sudo aptitude install smstools
And you have to do some small configuration by editing /etc/smsd.conf

```
#just edit the GSM1 section
[GSM1]
#init =
#here enter the ttyUSBx from dmesg
device = /dev/ttyUSB1
incoming = yes
#enter you pin here
pin = xxxx
baudrate = 115200
```

Now restart the service

    sudo /etc/init.d/smstools restart

And check the log that it started as it should

    sudo tail /var/log/smstools/smsd.log
