Progress of the project

Week 1 (January 11th - January 17th)

• Choice of the project

Week 2 (January 18th - January 24th)

• Discovery of the project
• Discovery of the already existing technologies
• Test of the given instruments (iTag, STM32...)
• Writing the requirements specifications

Week 3 (January 25th - January 31st)

• Writing of the UML diagrams
• Definition of the structure of the project

Week 4 (February 1st - February 7th)

• Receipt of the TI Simplelink SensorTag
• Trying to make the sensor work

Week 5 (February 8th - February 14th)

• Elaboration of the design patterns to use in the project
• Tests writting designed to understand the Genuino board functionning
• Making the Genuino beacon emit signals is not possible for the moment according to the following website : arduino.emitting-problems

We will keep an eye on the evolution of the Genuino emission problem, our project will be designed to allow the treatment of Genuino beacon data. But since time is running out, we will concentrate on the other beacons.

Week 6 (February 15th - February 21st)

Before splitting the work into parts for each member of the group, we agreed on the common format of data to use and which attribute is useful between one another. There are four main parts :

• Transmission of data from the beacons to the server
• Extraction and treatment of the received data
• Emission of the triangulated coordinates to an android client
• Treatment of the coordinates and display of the result on the client' screen.

/* Ajouter des contraintes-spécificités de chaque partie (ex : protocole MQTT...)*/

Week 7 (February 22nd - February 28th)

Each one of us work on a defined task.

• Beacon emission : board receives BLE packets (sorting them between different MAC addresses) and then computes the ratio of signal strengh over signal average strengh.
• Server (beacon side) : allow the transmission of data (in a raw state) to the server which will compute the distance according to the RSSI formula
• Server (android side) : Development of the MQTT server sending position to the Android clients
• Android : evaluation of the functionnalities proposed by the application.

Week 8 (February 29th - March 6th)

• Beacon emission : board receives BLE packets (sorting them between different MAC addresses) and then computes the ratio of signal strengh over signal average strengh.
• Server (beacon side) : allow the transmission of data (in a raw state) to the server which will compute the distance according to the RSSI formula
• Server (android side) : Development of the MQTT server sending position to the Android clients
• Android : we found that the Android library OSMDroid might help us doing the rendering of a map on smartphones. Using leaflet could also help us empiling multiple objects

Week 9 (March 7th - March 13th)

Presentation support : File:Mi parcours.pdf Preparation of the presentation.

Week 10 (March 14th - March 20th)

• Android : Looking for similar project such as OpenLevelUp. We were thinking of using the same structure of file to describe a building.
