Hello,
I tested with ping/sonar and tried at first the ping_config_and_read. This does not work because there is a mixup of the PyMata-instance-variable (once called firmata and once called board).
I changed the source to the following and did some additional comment on it; maybe it's better this way. Works fine on Arduino Uno with FirmataPlus under Windows (server 12) with Python 2.7 (Python(x,y) in my case).
Here the working code:
