Using PySerial is it possible to wait for data?

Question

I\'ve got a Python program which is reading data from a serial port via the PySerial module. The two conditions I need to keep in mind are: I don\'t know ho

Answer 1

Ok, I actually got something together that I like for this. Using a combination of read() with no timeout and the inWaiting() method:

#Modified code from main loop: 
s = serial.Serial(5)

#Modified code from thread reading the serial port
while 1:
  tdata = s.read()           # Wait forever for anything
  time.sleep(1)              # Sleep (or inWaiting() doesn't give the correct value)
  data_left = s.inWaiting()  # Get the number of characters ready to be read
  tdata += s.read(data_left) # Do the read and combine it with the first character

  ... #Rest of the code

This seems to give the results I wanted, I guess this type of functionality doesn't exist as a single method in Python
