what is the chance of someone smarter than me getting this working on the n810 with python. It seams to be a serial device with very limited commands
a returns meters traveled and time in milliseconds from the last 'a'
b i have no idea maybe nothing in the simulator
c returns time since last 'c' , meters, speed,acceleration.
se|xxx> sets the ratio in 1/hundreds of a revolution to the width of a
tennis court.
it would be useful to log speed against gps position. with a little imagination you could also get cadence and power.
