MMM-OralB / Bluetooth equipped toothbrush integration

SvenSommer

@lavolp3 Thanks for your post. I will have a look into this, hopefully in the next week! I’m still convinced we should build this module.

@SvenSommer Thanks Sven and good you’re back on this :-)

I have one question on noble I can’t figure out.
with noble.on('discover') I can exchange information on discovery, so as soon as the brush sends a certain signal. All good.
But how can I trigger the brush to send its manufacturedata, let’s say, every 2 seconds?
Or is that not possible at all?

A small heads-up: Still not getting to terms with noble.

But as I had some connection problems today, I used bluetoothctl again to connect to my brush.
And found out that scanning with bluetoothctl gets a constant output of the manufacturerData of the brush.

With bluetoothctl it would be able to get information on

running time
mode (on/off)
quadrant
in an interval of like 10 seconds

Hey guys,

I have tracked this topic for a while and I have created an own module for bluetooth devices based on (https://github.com/Hypfer/Cybele). Currently only Oral B toothbrush is supported: https://github.com/timodejong95/MMM-BluetoothDevices

I am still testing it but it seems to work stable’ish. Although I cannot test it with an actual mirror because that is still work in progress. If you want to check it out and test be my guest. If you have any improvements or tips let me know!

Hope this helps out.

@timodejong95 GREAT!!
I’ll try it out now.
One comment to the readme.
You have given the config entry in JSON style (with hyphens around the keys).
Config entries are in JS style.
I guess devices should also be an array of JS objects?

Then it should be like this:

    {
      module: "MMM-BluetoothDevices",
      position: "bottom_bar",
      config: {
        devices: [
          { type: "OralBToothbrush", name: "OralB", mac: "" }
        ]
      }
    },

@lavolp3 Also mentioning in the Readme that npm install is necessary would be helpful

OK I have a first error message

no Toothbrush activated yet. Only started the mirror with npm start dev.
Running on a RasPi 3b w/ on-board bluetooth

Ooh good one, I have some time tonight, will update the docs.

Hmm you running on raspberry pi do you got bluetooth enabled? Can you find the toothbrush if you use the GUI bluetooth?

If you got the time could we skype or call, it’s faster to tackle issueus, PM me about that.

lavolp3

@timodejong95 that’s rather difficult for me juggling with family, (home) office and several other things I have to say. Will think about this and let you know.

I have worked successfully with bluetoothctl and noble (npm).
Both were able to connect to the brush.
With bluetoothctl I got a constant stream of the manufacturer data that contains some info. (see above)
I used that straight from the console.

@timodejong95 OK I have identified the source of the error.
It originated from the connectDevice function on Dongle.js
I had a wrong mac address for the brush which leads to an unresolved promise.
Good luck finding the promise :smiling_face_with_open_mouth_smiling_eyes:
(I love/hate promises…)

Correcting the mac address I get new unresolved rejection errors.

So… Software caused connection abort. Don’t know what that means unfortunately. Guess I need to learn a bit more about the connection process. But I get the feeling that this module is a bit too complex for just using with my toothbrush.
Let me know if you know my problem.
