We get this back from dbus 2022-08-09 11:11:02.209 DEBUG (MainThread) [bleak.backends.bluezdbus.manager] received D-Bus signal: org.freedesktop.DBus.Properties.PropertiesChanged (/org/bluez/hci0/dev_FA_8F_A4_3F_A3_2B): ['org.bluez.Device1', {'UUIDs': <dbus_next.signature.Variant ('as', ['0000003e-0000-1000-8000-0026bb765291', '00000043-0000-1000-8000-0026bb765291', '00000055-0000-1000-8000-0026bb765291', '000000a2-0000-1000-8000-0026bb765291', '00001800-0000-1000-8000-00805f9b34fb', '00001801-0000-1000-8000-00805f9b34fb', '1b7e8251-2877-41c3-b46e-cf057c562023', 'ae5d1e47-5c13-43a0-8635-82ad38a1381f', 'b0733e83-8434-4c00-a344-25d1c982a0ef'])>, 'ServicesResolved': <dbus_next.signature.Variant ('b', True)>}, []]

bdraco · 2022-08-09T21:59:47Z

Could be related to bluez/bluez#316 but I don't think so

dlech · 2022-08-26T21:32:39Z

Did you log Bluetooth packets with Wireshark to see if this device isn't following the Bluetooth spec which could cause BlueZ to skip the characteristic?

bdraco · 2022-08-26T21:34:22Z

I did but its sitting on a computer 4000 miles away that I can't get to at the moment.

Let me see if I have one of them here.

bdraco · 2022-08-26T21:42:42Z

Found a device that has the issue. Any specific capture flags that would be helpful?

Based on the linked BlueZ issues, I would look at the "Read By Group Type Response" packets.

Nov 06 19:14:58 homeassistant bluetoothd[401]: src/device.c:store_chrc() Error storing characteristic - can't get data

This appears in the log for the chars that it can't process

bdraco · 2022-12-24T00:40:39Z

I was hoping the patches in home-assistant/operating-system#2285 would fix this issue but it looks like its a different problem with BlueZ

Dec 24 00:31:37 homeassistant bluetoothd[406]: src/device.c:store_chrc() Error storing characteristic - can't get data

bdraco · 2022-12-24T00:53:57Z

It might be fixed in newer bluez actually since Error storing characteristic no longer appears in the bluez source

bdraco · 2024-04-18T03:10:42Z

might be solved by bluez/bluez@7604a57
