asyncio.exceptions.CancelledError

[EarthK]

I have Raspberry Pi 4 Model B Rev 1.1 (Linux earth-ha 5.15.61-v7l+ #1579 SMP Fri Aug 26 11:13:03 BST 2022 armv7l GNU/Linux) and Aranet4 (firmware v0.4.10).

After I connected Aranet4 for the first time, everything was fine. With the command sudo aranetctl EF:C1:88:E1:31:D0 I got the actual data, but after a little while the following error appeared:

earth@earth-ha:~ $ sudo aranetctl EF:C1:88:E1:31:D0 Traceback (most recent call last): File "/usr/local/lib/python3.9/dist-packages/bleak/backends/bluezdbus/client.py", line 171, in connect reply = await self._bus.call( File "/usr/local/lib/python3.9/dist-packages/dbus_fast/aio/message_bus.py", line 337, in call await future asyncio.exceptions.CancelledError

During handling of the above exception, another exception occurred:

[bluetooth]# list Controller DC:A6:32:66:43:DF earth-ha [default] [bluetooth]# paired-devices Device EF:C1:88:E1:31:D0 Aranet4 00407

I can also see data coming from the Aranet device: [CHG] Device EF:C1:88:E1:31:D0 RSSI: -83

When the device is deleted in bluetoothctl and paired again, it is possible to receive data once again. Then the said error appears again.

Additionally and unrelatedly, when I got the data from Aranet, I found that the firmware version does not match what is shown on the phone.

I'm having this same issue. I have to remove the device and repair every time I run aranetctl; otherwise I get asyncio.exceptions.CancelledError just as @EarthK shared.
