GPS_Android

Description

This repository contains all code related to the Android app of TU Ilmenau group project called Performance analysis framework for base station placement using IEEE 802.11

Functionality

The app allows sending device location to the 'MessageBroker' component using MQTT queue. Available interaction options:

current IP address shown
switcher to permit continuos address sending
new attempt time-out after fail adjustment
manual address pushing

System requirements

Android Studio
min SDK version 14
target SDK version 29

How to use

clone the repository
import to Android Studio
establish connection MQTT broker
launch on virtual or a real device, they must be connected over wifi network.

gps_android's Issues

Manually choose FTP server to test uplink\downlink spped

That would be good if there will be a field where you can put an IP address or DNS name to use for UP\DL testing.

Like the MQTT Broker address field, that issue may be resolved the same way.

Send a date of message in Android in ISO format, not integer

Currently, the message's date is like 122213124124 - that's okay, it's possible to convert, but you lose your timezone.

The better way is to send a string of dates in ISO format. See examples:

"2005-08-09T18:31:42"

App crashes after trying connect to MQTT Broker

Detected in #d5b5812773fbd5fc62c0b10518148a4f8fbb8354
A way to reproduce

Enter IP addres for MQTT
Push button "Connect"
See the crash

Tested on Android 9.

Thread for continuously pulling doesn't stop when it's toggled to off.

How to reproduce:

Start the app, toggle on "Push continuously", wait for a little, toggle it back.

Expected result

No data is transferred, label's text remains the same

Given result:

In Debug windows there appears messages coming from UL\DL speed estimation, labels are continuing to change.

Android stops async task when sending continuously

Prepate experiment description

Deadline - 3th February

We should prepare experiment description as well as all documents required for running experiments.

There should be:

Formal description what we want to do, why we want to do, what do we expect?
Experiment Environment description: what are the conditions?
Experiment Case Set: what do we do, how we do, what input data are, what are the results?

Show Android DeviceID on the Android's gpsTracker app.

There must be a label field on the Main Activity screen to show the current DeviceID.

Function to access generated messages in offline DB

THe problem here is to store measurement in local DB (maybe SQLite with JSON functions, or raw file) in parralil while trying to send to MQTT Broker.

Then the stored DB can be uploaded to server after connection go back.

What to do

Extend functionality to save each message in local file
Add functionality to send each message from local file
Add functionality to show the location of the file

The Location Label is not updating either pushing manually or continuously
The labels for UL/DL overlap so the info is shown ambiguously.

Force GPS message to be sent whenever the location is changed

Use whether GPS_PROVIDER/NETWORK_PROVIDER, but data must be sent periodically or by button press.
