UnhandledPromiseRejectionWarning and other errors

[corgan2222]

I tried now for months to get this running stable, but every few minutes it stopped working.
And i can't really reproduce the problem. Its such a strange behavior.

I restart bluetooth, the restart the keyble-mqtt service.
And some seconds later i get this error.

Then i repeat this, restart BT and keyble i got a different error from noble

And now, if I repeat this one more time, restart bt and keyble, I get this smp error, but keyble does the job and turn the key.
At first i was worried about the snp error, but now its a hint that the communication is working.

This behavior is completely random.
ATM i have a cron job running, which restarts BT and keyble every 5min, but even with this, the chance that the look opens if needed are <50%.

Is there anything i can do to help?

Had the same problems for a long time.
Found a solution by mirovdm/le_autoconnect_timeout.md in github
"This tool changes default HCI_LE_AUTOCONN_TIMEOUT for Bluetooth adapter on Linux"
And it works fine !

@jeeck-jan Thanks!

Some advice to make keyble software function fast and sure : for raspberry pi

1 enable bluetooth in /boot config.txt #dtoverlay=disable-bt
2 enable hciuart : sudo systemctl start hciuart
3 trust doorlock : sudo bluetoothctl trust xx:xx:xx:xx:xx (doorlock mac adresss), this is not so easy, do it in loop in python or
manually in bluetoothctl (several times till successful); you only have to do this one's : stays in raspi's memory : this speeds up
connection
4 adjust le connect timeout : see above (you can do this one's at every pi reboot )
5 do not change settings for --status_update_time : if to short your commands will be overruled by the status command, and
the doorlock will not move. (and you don't know what's happening)
6 I change the setting for timeout --timeout to 20, if you don't get a reaction after 10 seconds, you won't get any. This setting
is not realy necessary : I always have reaction in less than 10 seconds.
7 this is very important : before sending a command : stop bluetooth (sudo systemctl stop bluetooth), and then start bluetooth
(sudo systemctl start bluetooth), then send your command

That's it.

For me 100% successfull commands, time between command and moving the lock = 4 to 6 seconds (medium 5s)

Have fun !
