Bluetooth disconnects immediately after connecting about homebridge-brewer HOT 16 CLOSED

Hi,

@jaxter0ne Could you try to get it work with: https://github.com/petergullberg/brewbutton#brewbutton-in-the-browser
Check the browser sample in chrome, if that works it should work too using the plugin.

My first guess is maybe the token is wrong?

Thanks,
Thom

Thanks for your reply! I encounter the same problem with the brewbutton.
I'm quite a newbie and have tried multiple times to get the token and I've got the same result each time. Do you have a real step by step way to retrieve it using a Mac, iPhone, Android phone? (I just don't have a PC)

Thank you very much!

from homebridge-brewer.

@jaxter0ne unfortunately it is quite hard to get the token. I added a guide to the Readme, I know its technical but this was for me the easiest way with just a Mac and an Android device: https://github.com/tritter/homebridge-brewer#token

Do you paste the hexdump command line inside the Terminal on the mac or elsewhere? I can't seem to be able to make that command work...

Hi @jaxter0ne sorry for my late reply. Yes I think I used a Mac for that, but hexdump should be available on linux too.

Thanks for your answer.
This is what I get:

0B 00 04 00 12 14 00 83 AE B5 5A 12 84 24 98
0B 00 04 00 12 14 00 83 AE B5 5A 12 84 24 98

So my token should be: 83-AE-B5-5A-12-84-24-98
Right?

But it still doesn't work...

Oh and this is how the plugin is configured on HomeBridge, if maybe it's not configured correctly:

    {
        "machines": [
            {
                "displayName": "Nespresso",
                "name": "Expert_CDD376ED07FE",
                "token": "83-AE-B5-5A-12-84-24-98",
                "temperature": "High"
            }
        ],
        "platform": "Brewer"
    }
]

@jaxter0ne exactly looks good! Do you run on a raspberry do you have more Logs? Browser also didn't work for you? (https://github.com/petergullberg/brewbutton#brewbutton-in-the-browser)
Also make sure your phone is not connected to the machine (repower machine) as it can only have one connection at a time.

from homebridge-brewer.

It doesn't work in the browser either. This is what I get:

Requesting Bluetooth Device...
Connecting to GATT Server...
Getting Service...
Getting Characteristic...
established auth characteristic?
Writing Auth
authenticated
Notifications started
Reading status
Connected

Argh! NotSupportedError: GATT operation failed for unknown reason.

And then if I unplug and plug the machine again, this is what I get:

Requesting Bluetooth Device...
Connecting to GATT Server...
Getting Service...
Getting Characteristic...
established auth characteristic?
Writing Auth
authenticated
Argh! NotSupportedError: GATT operation failed for unknown reason.

@jaxter0ne Hmm is this maybe a newer version of the expert? :/ Are you sure its an expert? ;)

from homebridge-brewer.

Well yes it is an expert, I bought it second hand because it's not sold by Nespresso anymore.
Maybe European models are different?

from homebridge-brewer.

Almost think so, do you understand bluetooth a bit? It looks like you're authenticated correctly but the gatt services have an error. Could you try a bluetooth scanner or change the browser site to read your characteristics?
You should find/change ids like these: https://github.com/petergullberg/brewbutton/blob/f907f4779a79ec822358f9eb12f0d480ca149060/brewbutton.html#L77

In the BLE Snoop you should also find them, at leas the authentication should be the same: "06aa3a41-f22a-11e3-9daa-0002a5d5c51b"

from homebridge-brewer.

Hm no I have no idea how to do that unfortunately. Could I send you my btsnoop_hci.log file so you can look it up maybe? Or if you can walk me through it I can try.

from homebridge-brewer.

@jaxter0ne yes brew a coffee and send that snoop log, that should usually contain all data. Thanks for your patience.

from homebridge-brewer.

This is the latest one I did. Please tell me if you need a new one.

Thank you so much for your help!

from homebridge-brewer.

@jaxter0ne updated dependencies, may be fixed now.
