EstimoteSample

Unity project showing how to obtain data from Estimote sensors, through gateway https://github.com/cwi-dis/iotsaEstimotes.

The gateway is a wifi-enabled REST server running on an ESP32. It uses BlueTooth LE to obtain sensor readings from a number of Estimote sensors that are near to it.

The data is provided to the Unity app using REST over HTTP over TCP/IP over WiFi, so the Unity app only needs to use a module that can speak HTTP. No need for direct Bluetooth LE access in the Unity app.

Gateway setup

You will need to tell the gateway (the esp32 lolin board) your WiFi network and password:

• connect the board to power.
• It will not find the old WiFi network it was connected to. Therefore it will create a network itself, with the name config-estimotes.
• Join that network with your laptop or mobile phone.
• Open a browser, go to http://estimotes.local, check the board is working.
• Goto http://estimotes.local/config.
• Select Enter configuration mode after next reboot., press Submit.
• Press the little Reset button on the board, or power cycle the board.
• go to http://estimotes.local. It should now say something like In configuration mode configuration, will timeout in 291 seconds..
• go to /wificonfig and enter your WiFi network name and password. Press submit.
• The board should reboot and connect to the correct WiFi network. But maybe you have to power cycle it once more.
• Reconnect your laptop to your normal wifi network, and ensure you can still access http://estimotes.local.
• Now put a battery in the estimote, and at http://estimotes.local/estimote you can see the current state of the estimote.

Project structure

The EstimoteSample scene has everything:

• EstimoteTracker talks to the tracker. At the moment it gets a reading from a single estimote, and an interval that you can control. The URL field is where the data is gotten from.
• Dice_d6_blablabla has the dice, and the SimpleDiceBehaviour controls it.
