Cannot connect to Xiaomi Yeelight MJYD02YL-A #2

paulius2k · 2022-05-27T17:55:22Z

Hello,
I found your repo here.

I am trying to connect to Xiaomi Yeelight MJYD02YL-A.
I can connect using https://atc1441.github.io/Temp_universal_mi_activate.html tool.
However, it fails to "do activation":

Log:
20:49:24: Searching for devices

20:49:31: Detected Mi Thermometer
20:49:32: Connected
20:49:36: Activating now, please wait...

I thought your tool could help.
However I am getting an error (MAC removed):

paulius:~$ miauth xx:xx --register

What could be done here?
Thanks!

Hey @paulius2k,
please make sure that the Bluetooth adapter on your PC is enabled / turned on. You can check this with bluetoothctl but I recommend using the blueman frontend.

paulius2k · 2022-05-28T13:00:05Z

@dnandha - yes, it is enabled. I see my device in Blueman and I can connect to it.

dnandha · 2022-05-28T13:08:49Z

@paulius2k Ok, then please test if you can manually discover LE gatt services:

bluetoothctl
connect <mac>
list-attributes

Ah sorry, after connect <> type: menu gatt, after this you can do the list-attributes command.

@paulius2k Everything looks fine. You could try btmgmt le on and when using the miauth command I always put the MAC address in quotes and all lower-case, e.g. miauth "12:34:56:ab:cd:ef" - also try with sudo.

paulius2k · 2022-05-30T12:39:38Z

@dnandha - this is what I get:

paulius:~$ sudo btmgmt le on
Set Low Energy for hci0 failed with status 0x11 (Invalid Index)

For the miauth commands I still get errors:

@dnandha - any ideas how to go further? I'd appreciate your help.

dnandha · 2022-06-03T09:31:18Z

@paulius2k Yeah, so your hci index is 2 instead of 0 for some reason. In this line, could you try adding the extra argument iface=2 to the constructor and see if it connects?

paulius2k · 2022-06-03T10:46:20Z

Thank you for your support.

So like this?:

        self.p.connect(self.mac, btle.ADDR_TYPE_RANDOM, iface=3)

I tried different values (0 to 3): on 0,1,2 it throws error right away, on 3 it tries connecting for some time and then still throws an error:

paulius:~$ miauth "88:ab:bc:ff:11:22" --register

bluepy.btle.BTLEDisconnectError: Failed to connect to peripheral 88:ab:bc:ff:11:22, addr type: random

I see that blueman also uses hci3 when connecting to that device:

Adapter: /org/bluez/hci3

I also noticed that blueman manages to connect to the device first, but after some time it throws a message Disconnected and Pairing failed for 'my_mac'

dnandha · 2022-12-18T16:33:31Z

It seems that the device is refusing a BLE connection altogether. I would suggest a look into the Homebridge project and then installing one of the available Xiaomi Yeelight plugins.

bwomsm1 · 2023-03-15T13:59:48Z

Hi @dnandha, I am also facing the same exception error,
I was trying to connect to the device with bluetoothctl and then connect <my mac address> but it also fail,
Does it means that I cannot connect to the device which I am trying to?

mptei · 2023-12-10T18:44:10Z

The reason that it can't connect:
bluepy.btle.BTLEDisconnectError: Failed to connect to peripheral 88:ab:bc:ff:11:22, addr type: random
is the addr_type. If I change that to btle.ADDR_TYPE_PUBLIC in miauth/ble/blue.py it connects and tries to register.

But it fails then with other errors.

mptei · 2023-12-10T18:49:48Z

The best what I can get is:
