Example CR10X Program using the Polling Method
This program will deal with sensors that send data at random intervals. The
program polls the SDM-SIO4 to see if data is available and only stores the data
then.
A typical filter that could be used is as follows:
fltst 200 "t[data]A5xff"
This filter works as follows:
t[data]
– this filter waits for an exact string match before it starts the next filter.
In this case it is waiting for the sensor to send the string ‘data’.
