'''
This module does prepare and upload the ALL_WSPR.TXT-format to the influxdb-server
Author : PA7T Clemens Heese clemens at pa7t.nl
DK5HH Michael Hartje DK5HH at darc.de
Parameters:
-fi inputfile (ALL_WSPR.TXT-format)
-fo <optinal> write a file in uploadformat to influxdb (see below)
-r Callsign of reporter
-rl maidenhead locator of reporter
-u influxdB user
-pw influxDB password
-host influxDB-Server name or IP
The upload of the output file (-fo output.daten) could be done with
curl -X POST 'http://127.0.0.1:8086/write?db=wspr&precision=s' \
-u user:passwort --data-binary @output.daten
Function:
reading from -fi Infile preparing the ALL_WSPR.TXT-format for upload
uploading with json-client to influxDB-Server -host if not given -fo outfile
Installation:
Prepare the python installation depending on what python version you are
using (2/3)
we need to add the modules in addition to a standeard python installation
influxdb
geohash
You can install these modules with for pythoon 2 with
pip2 install modulename
or for python 3 with
pip3 install modulename
check the installtion in python console
import modulename
(no answer is good news.)
