IoT Lab_4

tags: fh IoT

Group members: Sebastian Doiber, Johannes Schwinger

This lab exercise’s topic is LoRaWAN. We will use the LoRa Boards provided by the IoT-LAB: ST B-L072Z-LRWAN1 boards with ST MEMS extension X-NUCLEO-IKS01A2.

We will set up a LoRaWAN application which sends data o a network server; finally, we will connect our app to an application server (for a graphical presentation of our data. We will use the same setup as we did for lab exercises 1 & 2: Ubuntu 18.04. (VM) with RIOT-OS and the IoT-Lab.

Documents your work with screenshots and thorough expalanation where applicable.

First steps with TTN

Provide a screenshot of your data output at TTN.

After registering on TTN we created a new device according to the steps in the hackmd file we got from you.

We proceeded to configure the makefile of the ./lorawan experimant according to our generated data.
We later found out that one of the ID's had the wrong format which made it impossible to compile.
After fixing that we tinkered around a little bit but got it running in the end and got our output on TTN.

Data output at TTN

LoRa Example with Sensor Data, TTN, and Cayenne

Download the zip file from Moodle:

lab4_02_lorasensor.zip

Move the unzipped directory into your /myRIOT/examples/ directory ans follow the steps back in the hackmd.

Document your steps here with screenshots (IoT-Lab, TTN, myDevices) and thorough explanation.

  • What is your data output at TTN?

  • How is your data presented on the myDevices dashboard?

  • Adjust the settings of the widgets: e.g. display temperature as line chart. Use various widgets.

  • You can ownload your data als Excel file

  • Upload zip file containing main.c, Makefile.

Implementation

Problems when sending the data to the TTN. The applications works fine with no errors but the TTN-server only displays the initialisation message.

Virtual Worlds Questions

[TOC] Link to HACKMD file https://hackmd.io/@FH-SDJS/VR-AR-ExamQuestions Which are three ways of modeling 3D objects in VR? By Hand i.e. CAD Drawings | hand modeled: via appropriate tools like CAD software. This process CAN be supported by motion capture technology. Procedural Modelling | proceduraly generated: requires some data to work off but is a very time saving technique for things that populate the background 3D Scans of Real Objects: using depth-cameras, and volumetric methods or computertomography. This requires some additional steps:

QoL-Learning Diary

Team: Sebastian Doiber, Johannes Schwiner Important links: Our trello-board 18.06. First Sprint Was war bisher Im ersten Sprint haben wir einen Nav-Graph entworfen um eine Grundstruktur festzulegen und einen "Angangspunkt" zu haben. Dazu haben wir uns eine basic design Idee überlegt und versuchen uns an die zu halten (material.io). Zusätzlich wurde eine Klasse für die Zustandsprofile erstellt.

Secure Admin Tools – Lab Exercise 8 + 9

(c) Aymeric Hollaus, Sebastian Doiber, Johannes Schwinger Table of Contents [TOC] Procedure To make any actions on the server we needed to connect to the fh-campus-server by using our ID. For this process we used an SSH clinet. The first thing we did to set us up for the lab, is unsing Nmap to make a port scan. This allowed us to see every open port and the associated servies. To find any exploits we reseached the services and the OS revealed by the nmap scan. If we did find a possible exploit we used metasploit to check if it works.

For the http (pretty) Version, visit: https://hackmd.io/@FH-SDJS/SAT_Lab7 Name: Sebastian Doiber, Johannes Schwinger :::warning Note: We originally planned on submitting 2 seperate protocols but since especially at the last point our answers merged together we decided to submit the same protocol. Thats why the first few points have answers labeled "Sebastian" and "Johannes". ::: Angabe NMAP All the tasks have to be performed while being logged in to its.fh-campuswien.ac.at using your SSH credentials from the Scapy lab-exercise.
