Solve two-way serial communication #5

Closed GoogleCodeExporter closed 9 years ago

Currently the software only sends serial output by echo to /dev/ttyMSM2, 
which goes from the phone to the Arduino RX pin. We'd like to get commands 
sent from the Arduino TX pin accepted by the phone.

The hardware should support this but pySerial isn't included in the Android 
Scripting Environment so we need a hack.

The python script now has a thread that reads any serial input and speaks it. 
The
thread is not 100% stable for an currently unknown reason but I'll work on it 
soon.
I have worked around the serial debugger problem by having the arduino wait 
100ms and
then flush the serial input after sending anything. Not pretty but it works.

Reader thread script is now stable and works well. 

Arduino still waits 100ms and flushes as a work around the kernel serial 
debugging.
