A5
– this filter sets up a 250ms filter time-out; this time-out should be long
enough for the sensor to transmit all of its data.
x
– this filter marks the start of the data set. In this case the data set is two
floating point numbers.
f
– this filter searches for the first ASCII floating point number to convert.
f
– this filter searches for the second ASCII floating point number to convert.
