TURRIS:GADGETS demo

Code in this repository is related to the TURRIS:GADGETS project. It is written in Python, which is available by default on router Turris.

Demos

gadget_command.py

Send individual commands to the TURRIS:DONGLE using this utility. You can use it to register individual sensors with the dongle.

gadget_echo.py

Listen to messages received by the dongle.

net_echo.py

Listens to messages received by the dongle and passes them to given IP addresses in UDP datagrams. net_collect.py may be used to capture the messages.

net_collect.py

Simple client which receives messages sent by net_echo.py as UDP datagrams and prints them out.

thermometer.py

Collect temperature measurements from a TP-82N thermometer and store them in a CSV file thermometer.csv. Also uses thermometer.html which may be used to display the collected data in a simple but nice JavaScript chart.

zeromq_echo.py

Another simple echo client. This time it uses ZeroMQ (a very nice broker-less message queue for message transport). See zeromq_collect.py for more details.

Requires the pyzmq external library.

zeromq_collect.py

ZeroMQ client receiving data from zeromq_echo.py. Serves as a demo of an application where the messages may be distributed to several clients, courtesy of ZeroMQ.

Requires the pyzmq external library.

device.py

Not a demo in itself. This is a simple communication library which is used by the other demos.

How to configure Turris for the dongle

The TURRIS:DONGLE uses an USB to serial converter from FTDI. Because of this, the required kernel module must be installed for the communication to work and the /dev/ttyUSBx device to appear.

The module to install is kmod-usb-serial-ftdi. You can do it from the command line:

opkg install kmod-usb-serial-ftdi
