Hi All, raspberry pi 3 bluez v5.39 testing platform client/bluetoothctl I have a ble peripheral device advertising a custom uuid. Within bluetoothctl when I try to connect to it after a filter is set, one third of the time I get an error. There is no problem if no filter is set, turning scanning off before the connect command does not help. Here is an example flow within bluetoothctl [bluetooth]# set-scan-filter-uuids f655b638-fead-4268-b07c-e5d79d09b22b SetDiscoveryFilter success [bluetooth]# scan on Discovery started [CHG] Controller B8:27:EB:37:3F:CD Discovering: yes [NEW] Device CF:05:30:F2:6F:5E CF-05-30-F2-6F-5E [bluetooth]# connect CF:05:30:F2:6F:5E Attempting to connect to CF:05:30:F2:6F:5E [CHG] Device CF:05:30:F2:6F:5E Connected: yes Failed to connect: org.bluez.Error.Failed [CHG] Device CF:05:30:F2:6F:5E Connected: no Any ideas?
