Thunderboard Setup

I had a very difficult time following this tutorial so I am writing this to help me and other people. I would recommend following the directions in the tutorial using this page for reference if things go wrong.

I did this whole process on my Raspberry Pi 3 with Raspbian OS.

Following the GitHub doc

First things first: clone the repository.

git clone https://github.com/SiliconLabs/thundercloud.git

I believe this is what you need to install node.js and npm on the Raspberry Pi 3

sudo apt-get install nodejs npm

Once you have installed you will need to run gulp

When I tried to run gulp at first I had issues with missing modules. This is what I used

sudo npm install gulp-browserify gulp-plumber 

... including all the rest you will need. You may need to do

sudo npm install -g

to add things globally but I don't know what that means so I didn't worry about it.

Here is the reference: installing gulp modules

After you get gulp watch to work (not sure what it does), you will want to run gulp build.

Once this runs you will want to enter your thundercloud folder

cd thundercloud

I extracted the zip file from the tutorial to the the thundercloud folder.

Installing Bluepy

Following these instructions you will see

sudo apt-get install python-pip libglib2.0-dev
sudo pip install bluepy

Firebase

You will need the command line tools. The link on the GitHub is outdated. Use this one.

Following the directions there all you will have to do is

npm install -g firebase-tools
firebase login

You will then login with your Google account and should now be able to use Firebase commands.

You will then run

firebase deploy --project <your firebase project id>

Make sure you are in the thundercloud folder when you run this.

*When you create a Firebase account you will create a project. The project will have a project ID. This will be "yourprojectname-5555" or something similar. This is the project name you will be using throughout the tutorial. Don't just use "yourprojectname"

Scanning for Thunderboards

Make sure your Thunderboard is turned on and run

sudo python tbsense_scan.py

This script will scan for Thunderboards and every time it detects your Thunderboard it will return the sensing data.

Final notes

I still was unable to get the Silicon Labs app to work on the firebaseapp.com URL. I was able to see the real time database updating in Firebase but I was unable to see the visual Firebase app.

Here are the files from the original tutorial that you will need to download if you didnt already http://community.silabs.com/mgrfq63796/attachments/mgrfq63796/9/513/1/thunderpi.zip

Thanks for your help!
But I have a question. How can I ran gulp watch?
I have just installed the gulp modules. But when I type in "gulp watch" in thundercloud folder it says:

pi@raspberrypi:~/thundercloud $ gulp watch
module.js:540
throw err;
^

Error: Cannot find module 'gulp-concat'

MCRingo, if your issue is still unresolved, try
npm install gulp-concat

For installing all missing modules of gulp (I had to install a great deal of them manually), try this command https://www.npmjs.com/package/npm-install-all to install them all at once

@hornej : Did you succeed with your sense2 ?

I keep getting this BTLE exception for whatever field I try to read.

@Xoib $ @hornej I'm getting the same error when running tbsense_scan.py ? I tried three different Bluetooth adapters?

@hornej I am not able to access the official thundercloud repo. Is it down? If it is taken down, you by any-chance know why that might be.
And one off-topic question. With Rpi3 how many Thunderboard can u track at a time?

@manimathma it looks like they took down the Firebase cloud functionality because of a security vulnerability, see here

I am not sure how many Thunderboards you can track at a time (I haven't used them in a few years) but I don't see why you shouldn't be able to track multiple.

Bonjour, quelqu'un peut m'aider SVP j'utilise thunderboard sense2 j'ai suivie toutes les étapes mais j'ai toujours des erreurs sous python
pour la comande scanner(), merci d'avance
