Python Script

The following code performs the same function, but has been placed inside a Python

wrapper using PySerial to show how you can script actions for the AT parser.

import io

import sys

import serial

import random

from time import sleep

filename = "hrm.py"

ser = None

serio = None

verbose = True # Set this to True to see all of the incoming serial data

def usage():

"""Displays information on the command-line parameters for this script"""

print "Usage: " + filename + " <serialPort>\n"

print "For example:\n"

print " Windows : " + filename + " COM14"

print " OS X : " + filename + " /dev/tty.usbserial-DN009WNO"

print " Linux : " + filename + " /dev/ttyACM0"

return

def checkargs():

"""Validates the command-line arguments for this script"""

if len(sys.argv) < 2:

print "ERROR: Missing serialPort"

usage()

sys.exit(-1)

if len(sys.argv) > 2:

print "ERROR: Too many arguments (expected 1)."

usage()

sys.exit(-2)

def errorhandler(err, exitonerror=True):

"""Display an error message and exit gracefully on "ERROR\r\n" responses"""

print "ERROR: " + err.message

if exitonerror:

ser.close()

sys.exit(-3)
