After renaming HC-05 to VC99, bluetooth serial port in OSX was /dev/cu.VC99-DevB
By launching serial motor, Arduino IDE connects to Bluetooth, HC-05 switch from fast to slow blinking indicating connection. QtDmm was not able to establish connection to HC-09. It would say connecting, blink rate would change, but did not work out of the box
Switch on rs232 on VC99 now or even before establishing connection
Process incoming data, log, display in a browser.. todo decode the rest of the.
The digits and polarity clearly visible, need to work out the rest of the bytes, suggested protocol was VC820 14 byte binary, this might be a good start http://www.mtoussaint.de/cdmm/doc/html/classVC820.html
