I’m amazed by the quality of your picture with IR-Light.
What kind of IR lamp are you using?
I’m also using a raspi noir camera and integraded like 30 IR-Leds within the mirror to get a brighter picture.
But always have problems with the face recognition. I assume it’s because the pictures used for comparing a black and white and for contrast reasons much darker.
Hey,
I have bad news.
The readable informations provided by the brush via bluetooth aren’t changing. Not while the toothbrush is running. I guess the characteristics we were able to readout, are used like placeholder for the sdk.
Second try was to get notified if a broadcastd value (characteristic) is changing. Nothing here either.
Every characteristic (like brushing time, battery level, etc) is using the same id and only provides a different name. So a notification service wasn’t possible.
Seems like there is no way to get the information read out via bluetooth without using the sdk…
I also tried to include the provided sdk into the MM-framework.
Therefore I had a try with node-java, which allows to run java classes within nodejs. The files from the android sdk are java classes.
It went pretty nice in the beginning. But then I ran into an error
‘Expected stackmap frame at this location.’ which is caused by the compiling the sdk classes on another system (linux not android), I would assume.
I was amazed that I wasn’t able to find any code snippets of frameworks from other developers to “hack the brush” when I first started. By now its seems obvious that it’s not that easy.
If anybody else is gonna have a try, please don’t hesitate to ask if you need assistance.
So noble is working fine. I find all bluetooth devices as expected, as long it’s not running within the MM-framework.
It seems like noble isn’t able to power on the bluetooth adapter on the raspberry pi3 board when started by magicmirror.
Any ideas?
Here is a minimal example:
var noble = require('noble');
console.log('stateChange is: ' + noble.state);
noble.on('stateChange', function(state) {
console.log('changed state to: ' + noble.state);
if (state === 'poweredOn') {
noble.startScanning();
}else {
noble.stopScanning();
}
});
console.log('stateChange is: ' + noble.state);
leeds to:
stateChange is: unknown
stateChange is: unknown
with the help of @dfuerst we were able to solve this issue by rebuilding electron with a special version:
sudo npm rebuild --runtime=electron --target=1.4.6 --disturl=https://atom.io/download/atom-shell --abi=50
I already had a look to the API provided by OralB. It’s quite disappointing.
They will provide you with classes to develop tools for android or ios apps. Not what we are looking for right now. :wink:
But maybe the documentation could be usefull.
I tried to find the forum page you mentioned. Found nothing usefull yet. Maybe you can have a look and help me out here.
I made a first attempt with noble and got some pretty nice results by reading out the braodcasted information from my brush.
I you wanna try on your own, do the following:
sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev
sudo ln -s /usr/bin/nodejs /usr/bin/node
npm install noble
var async = require('async');
var noble = require('./index');
var OralB_manufacturerData = 'dc00010205030000000101';
console.log('Lookinhg for OralB Toothbrushes with manufacturerData: "' + OralB_manufacturerData +'"');
noble.on('stateChange', function(state) {
if (state === 'poweredOn') {
noble.startScanning();
} else {
noble.stopScanning();
}
});
noble.on('discover', function(peripheral) {
var advertisement = peripheral.advertisement;
console.log('Found device with manufacturerData: "' + advertisement.manufacturerData.toString('hex') +'" localName: ' + advertisement.localName);
if (advertisement.manufacturerData.toString('hex') === OralB_manufacturerData) {
noble.stopScanning();
console.log('peripheral with ID ' + peripheral.id + ' found');
var localName = advertisement.localName;
var txPowerLevel = advertisement.txPowerLevel;
var manufacturerData = advertisement.manufacturerData;
var serviceData = advertisement.serviceData;
var serviceUuids = advertisement.serviceUuids;
if (localName) {
console.log(' Local Name = ' + localName);
}
if (txPowerLevel) {
console.log(' TX Power Level = ' + txPowerLevel);
}
if (manufacturerData) {
console.log(' Manufacturer Data = ' + manufacturerData.toString('hex'));
}
if (serviceData) {
console.log(' Service Data = ' + serviceData);
}
if (serviceUuids) {
console.log(' Service UUIDs = ' + serviceUuids);
}
console.log();
explore(peripheral);
}
});
function explore(peripheral) {
console.log('services and characteristics:');
peripheral.on('disconnect', function() {
process.exit(0);
});
peripheral.connect(function(error) {
peripheral.discoverServices([], function(error, services) {
var serviceIndex = 0;
async.whilst(
function () {
return (serviceIndex < services.length);
},
function(callback) {
var service = services[serviceIndex];
var serviceInfo = service.uuid;
if (service.name) {
serviceInfo += ' (' + service.name + ')';
}
console.log(serviceInfo);
service.discoverCharacteristics([], function(error, characteristics) {
var characteristicIndex = 0;
async.whilst(
function () {
return (characteristicIndex < characteristics.length);
},
function(callback) {
var characteristic = characteristics[characteristicIndex];
var characteristicInfo = ' ' + characteristic.uuid;
if (characteristic.name) {
characteristicInfo += ' (' + characteristic.name + ')';
}
async.series([
function(callback) {
characteristic.discoverDescriptors(function(error, descriptors) {
async.detect(
descriptors,
function(descriptor, callback) {
return callback(descriptor.uuid === '2901');
},
function(userDescriptionDescriptor){
if (userDescriptionDescriptor) {
userDescriptionDescriptor.readValue(function(error, data) {
if (data) {
characteristicInfo += ' (' + data.toString() + ')';
}
callback();
});
} else {
callback();
}
}
);
});
},
function(callback) {
characteristicInfo += '\n properties ' + characteristic.properties.join(', ');
if (characteristic.properties.indexOf('read') !== -1) {
characteristic.read(function(error, data) {
if (data) {
var string = data.toString('ascii');
characteristicInfo += '\n value ' + data.toString('hex') + ' | \'' + string + '\'';
}
callback();
});
} else {
callback();
}
},
function() {
console.log(characteristicInfo);
characteristicIndex++;
callback();
}
]);
},
function(error) {
serviceIndex++;
callback();
}
);
});
},
function (err) {
peripheral.disconnect();
}

});
});
}
sudo node toothbrush.js

Hey @yawns,
I tried to rebuild noble and bluetooth-hci-socket by:
npm uninstall bluetooth-hci-socket
followed by
npm install bluetooth-hci-socket
within the /home/pi/MagicMirror/modules/MMM-OralB/ - folder and also the
npm rebuild bluetooth-hci-socket
which should to to same.
Same for the hole noble package within the same folder.
Hey guys,
I need some advice how to get a bluetooth javascript-package running within the MM framework.
I tried to install noble to search for a bluetooth device. As I followed the installation instruction on the linked page, I was able to get the package running in a simple test enviroment.
Unfortunately I wasn’t able to get noble running within the MagicMirror framework.
I tried to install it with npm and several versions of node.js (6.x and 7.x) but got always an error
"Error: Module version mismatch. Expected 50, got 51." [node.js 7.x] or
"Error: Module version mismatch. Expected 50, got 48." [node.js 6.x]
within the bluetooth-hci-socket - part of noble.
I tried rebuilding the noble included packages and tried it also with a clean Magic Mirror installation under node.js 7.x. unfortunately nothing helped.

@dfuerst Hey, I liked your approach how to get the information about a running or a stopped toothbrush.
So, I played some time with hcitool within the console and checked the responsive times(if the toothbrush is beeing detected as connected or not, as a turn it on or off). Unfortunately, this wasn’t very reliable nor very accurate.
I would suggest a better approach is to use a javascript library for bluetooth such as noble to track if the toothbrush is connected or not.
Unfortunately I wasn’t able to get noble running within the MagicMirror framework. I tried to install it with npm anbd several versions of node.js (6.x and 7.x) but got always an error like "Error: Module version mismatch. Expected 50, got 51." within the bluetooth-hci-socket - part of noble.

@lolobyte
Thank you for the links.
For central america I found the following source the most usefull. Unfortunately it’s only available in high resulution.
http://goes.gsfc.nasa.gov/goescolor/goeseast/overview2/color_lrg/latestfull.jpg
Has anybody found more usefull sources by now?
