Concept proof of exchanging data between ArduinoBT and a S60 Mobile Phone (Nokia N73) via Python for S60
Here a proof of concept of interfacing ArduinoBT with a Nokia N73 phone via Python for S60. The Python code is horrible (i am not really a coder) but it works and i hope that
this primitive demo leads to further development and postings about BT and S60 mobile phones.
As a side note: the Python part of this demonstration can be with slight modifications used also to connect the mobile phone to any BT serial ports, like a GPS device or a computer running PD, MAXMSP or custom made software.
Info about python for s60:

What it does: When the python scripts starts it sends ascii 49 to the arduino BT which then returns the numbers 0-60 which are written into a file and stored on the memory card. Stupid i know :-) but its just a test.
