bluetoothctl "Failed to connect: org.bluez.Error.NotAvailable" while connect to Sony DPT-RP1 digital paper

I'm trying to connect to Sony DPT-RP1 digital paper from Ubuntu 20.04. From the bluetoothctl interface, pairing is successful however I just can't connect to the device. Sorry I'm completely noob in Linux and I'm trying my best to be informative. bluetoothctl connect A8:1D:16:07:DA:B4 gives: [bluetooth]# connect A8:1D:16:07:DA:B4 Attempting to connect to A8:1D:16:07:DA:B4 [CHG] Device A8:1D:16:07:DA:B4 Connected: yes [CHG] Device A8:1D:16:07:DA:B4 ServicesResolved: yes Failed to connect: org.bluez.Error.NotAvailable And after seconds: [CHG] Device A8:1D:16:07:DA:B4 ServicesResolved: no [CHG] D
