Jump to bottom

Tuhi is (currently) split into a server component and a GUI component. For debugging it is possible to run just the server component and interact with a custom commandline tool called kete.

This is a quickstart to get you up and running with Tuhi Kete. For details, see the Terminology page.

First, start the DBus session daemon without a GUI. From the git repository, simply run:

$ ./tuhi-server.py

Tuhi Kete

kete is the commandline tool to interact with Tuhi featuring an interactive shell. kete is only available in the git repository and does not get installed.

Registering a device with Tuhi Kete

The above process of registering a device is as follows:

$ ./tools/kete.py
Tuhi shell control
INFO: Connected to the Tuhi daemon
tuhi> search
INFO: Search started
tuhi>

Now hold the device button until the blue light starts flashing and you'll see:

INFO: Unregistered device: DC:2C:26:A0:C9:A8 - LE Paper
tuhi>

Register the device with the Bluetooth address (tab-completion is available)

INFO: Unregistered device: DC:2C:26:A0:C9:A8 - LE Paper
tuhi> register DC:2C:26:A0:C9:A8
INFO: DC:2C:26:A0:C9:A8 - LE Paper: Press button on device now

Press the device button when prompted.

INFO: DC:2C:26:A0:C9:A8 - LE Paper: Press button on device now
INFO: DC:2C:26:A0:C9:A8 - LE Paper: Registration successful

And done. The device is now available in Tuhi.

Downloading drawings with Tuhi Kete

The info command shows some basic data of the device, including which drawings are available. The listen command starts to listen for new data on the device. To get the device to connect, press its button. This is usually only needed once, the device stays connected while Tuhi is running and listening and Tuhi will keep downloading data as it is made available by the device.

tuhi> info DC:2C:26:A0:C9:A8
DC:2C:26:A0:C9:A8 - LE Paper
	Battery level: 78%, discharging
	Available drawings:
		* 1518566232: drawn on the 2018-02-14 at 09:57
		* 1518570062: drawn on the 2018-02-14 at 11:01
tuhi> listen DC:2C:26:A0:C9:A8
[...]
tuhi> listen DC:2C:26:A0:C9:A8 off

To download a drawing, use the fetch command, either with the drawing's identifier or the all keyword:

tuhi> fetch DC:2C:26:A0:C9:A8 1518566232
INFO: LE Paper: saved file "LE Paper-2018-02-14-09-57.svg"
tuhi> fetch DC:2C:26:A0:C9:A8 all
INFO: LE Paper: saved file "LE Paper-2019-07-15-16-44.svg"
INFO: LE Paper: saved file "LE Paper-2019-07-15-16-45.svg"
...

And the SVG file will be available in your $PWD.
