Timeout when running command

[Duberry]

I'm getting a timeout when connecting to a device. The device is found by the --scan with the correct device id.

Ubuntu 22.04.4 LTS

Traceback (most recent call last):
  File "/home/dan/python3-idotmatrix-client/venv/lib/python3.10/site-packages/bleak/backends/bluezdbus/client.py", line 214, in connect

    await future
asyncio.exceptions.CancelledError

During handling of the above exception, another exception occurred:

Any ideas?

I'll add a somewhat embarrassed solution to this, the display was simply out of range. This was surprising, because by 'out of range' it was only about 2m away from the Bluetooth transmitter, but presumably the one attached to my intel PCI card doesn't have a great antenna!

Anyway, if you find this issue, try moving the display closer to the PC, even if it seems pretty close already!

Haha, okay. Thanks for clarification. Seems the bluetooth receiver itself is really bad. Either from the device or your PC. I should add a better error handling in that case. Thats not very friendly for users.
