MMM-OralB / Bluetooth equipped toothbrush integration

lavolp3 · Apr 17, 2020, 8:16 AM

@timodejong95 I used this gitlab snippet. Don’t remember how I got there. I guess from the homeassistant forum which is also working on that.
For more follow-up see my post in this thread

When I use bluetoothctl on my RasPi I am getting lots of output form the brush recently. I’m not sure why exactly, maybe because my Pi is coupled with the brush.

Do we have to look into one of these characteristics/desricptors for the value?

lavolp3 · Apr 17, 2020, 8:25 AM

@lavolp3 Well according to the gitlab code we’re looking for this:

Characteristic
        /org/bluez/hci0/dev_58_7A_62_3F_63_80/service001e/char002c

        00002902-0000-1000-8000-00805f9b34fb
        Client Characteristic Configuration

The characteristic is the one the referenced noble code is filtering for.

Now GO Timo!
Make brushing great again!

@lavolp3

Haha thanks man.

I have made some big changes, improved connecting devices, GATT service, characteristics and some more. I have also managed to get the battery value, but I have an issue: after around 15-30 seconds after connection successfully to the device the connection drops:

{"ServicesResolved":false,"Connected":false}

I haven’t figured out why this happens, all the normal data is still received. Only the battery status not, it needs to be connected. I haven’t push anything to the repo yet. First I want to look if I can get it working (fully).

Are you experiencing the same with noble or can you get the battery status after 30 seconds or 1 minute plus?

I keep you updated.

timodejong95 · Apr 18, 2020, 9:30 PM

I have been debugging it and it seems that the devices is ‘just’ being disconnected:

HCI Event: Disconn Complete (0x05) plen 4
    status 0x00 handle 64 reason 0x13
    Reason: Remote User Terminated Connection

I do not know why :/

timodejong95 · Apr 19, 2020, 7:10 PM

@lavolp3 Oke I have pushed some changes, see: https://github.com/timodejong95/MMM-BluetoothDevices. Don’t forget npm install.

I updated the configuration see docs. You need to add a track key to the device config with the value ‘battery’:

example:

devices: [
  { type: 'OralBToothbrush', name: 'oralb', mac: 'xxx', tracks: ['battery'], format: 'formatted' },
],

It’s still a bit buggy let me know what your experience is!

lavolp3 · Apr 20, 2020, 8:09 AM

@timodejong95 No luck yet.
No Battery status to be seen and this error in the logs

timodejong95 · Apr 20, 2020, 9:42 AM

@lavolp3 Damm ashame, could you post the logs above the error? If correct there should be 2 more error logs, and just to be sure it still works when you remove the battery track, right?

djerik · Apr 22, 2020, 5:44 PM

@timodejong95
I have removed the module, installed again and added the extra piece of configuration. The updated UI is working fine, but there is no battery indicator. Is this the log you are looking for?

@timodejong95 there are no logs above that.

This error vanishes when I deactivate the JSON.stringify function.
I have the feeling that everything is working, but the battery is not showing up at all.

Also, when closing the mirror (ctrl+c when I started it with npm start dev ) I get these errors:
