Two Thymios connected to one PC with Python

Massimiliano Rango 24 Apr 2015 13:00

I need to connect two Thymios to the same computer in order to control them with a single Python program. How can I do that?
I already tried with:

asebamedulla -d "ser:device=/dev/ttyACM0;remapLocal=1" "ser:device=/dev/ttyACM1;remapLocal=2"

but when I run the Braitenberg example (https://aseba.wikidot.com/en:thymioraspyexample) I get this error:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.InvalidArgs: variable motor.left.target does not exists in node thymio-II

I think I need to specify which node of the Aseba network I want to get the values from. But I don't know how to do that.

There are two problems:

• asebamedulla does not implement the node remapping feature, only switch does. This could be worked-around by using a switch and then connecting medulla to the switch.
• asebamedulla provides access to target by names, so even if identifiers are remapped, the two targets will still have the same name.

I have opened a wish issue on github to add these features, see https://github.com/aseba-community/aseba/issues/408
