#Version 0.0.1 - March 11 2017 - EBBB - Ebike Black Box
#Script to process Cycle Analyst data and ship it to influxDB
#The file received.txt is generated via script > python_serial.py
##This script processes the first line of the file, Formats it with Sed & Awk and the posts it to InfluxDB (database db=ebike) via curl.
