From 3f516e6fbfc702ed7ec7e1ff1e515e0e198ee40e Mon Sep 17 00:00:00 2001 From: Antonio Ospite Date: Thu, 24 Dec 2015 10:52:14 +0100 Subject: [PATCH 1/1] Add measure_call_setup_time_to_android.py This makes it easy to measure the call time when using the Android app as a receiver. The tool parses the "adb logcat" output and gets info from the SaveMySugar app log. --- src/measure_call_setup_time_to_android.py | 104 ++++++++++++++++++++++++++++++ 1 file changed, 104 insertions(+) create mode 100755 src/measure_call_setup_time_to_android.py diff --git a/src/measure_call_setup_time_to_android.py b/src/measure_call_setup_time_to_android.py new file mode 100755 index 0000000..a862fea --- /dev/null +++ b/src/measure_call_setup_time_to_android.py @@ -0,0 +1,104 @@ +#!/usr/bin/env python3 +# +# measure_call_setup_time_to_android - call setup time from PC to Android +# +# Copyright (C) 2015 Antonio Ospite +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
