Python script for using gprs-modem as remote access-point

Credits

• Firstly, script was initially borrowed from Teleofis company. So visit them: http://teleofis.ru

• Secondly, script works on telit hardware and on telit python interpreter. So visit them too: http://telit.com

• Thirdly, if you do not have access to Telit development toolkit (it is true for most of you), then here is handmade toolkit for linux: https://github.com/GROUNDLAB/Telit-Loader . It is initial point and you can't test and upload this script with it, but you can do it with my fork of that toolkit: https://github.com/seik0ixtem/Telit-Loader

Where it should work

• It is being tested on Telit GL868-Dual GSM module, so it must work with them.

• I believe, that it should MAINLY work on most of other Telit modules with python support.

What this script is designed for

Main idea is that GSM-module on its own connects to some server with TCP, makes some authorization and then allows server to manage this GSM-module.

What is "to manage" GSM-module (some features may be not implemented yet, some features may be missing in this list):

• Change any parameter of the script

• Put any at-commands to the device, and get results.

• Open new TCP connections from device to any destination for logging and debugging purposes

• Read state and change state of GPIO ports of the device

• Allow remote control by CSD reserve channel (by white list)

• Allow remote control by SMS (by white list)

• Send/get data to/from serial port of the device

• Create transparent bridge from device serial port to TCP connection

• Reboot

Also, device should do some work on its own:

• Sync time with server

• Make some specific operations with devices attached to its serial

How to use

This is not the only option, but it works:

1. Test this code on your own using, for example, Telit-Loader

2. Upload this code to device using, for example, Telit-Loader

3. Make main.py the main script on device using, for example, Telit-Loader

4. Reboot device in python mode (it differs with each manufacturer, read the manuals). Wait until all scripts compile (first time I waited about an hour).

5. See it working (or not). It will work differently with different settings.

Notes

Repo may include *.sample files, but script may need that files without .samples suffix. So, change settings in that file and rename it. I made that not to include my private data in configuration files and added private configuration files in .gitignore For example: settings.ini.sample.
