Hello, I'm trying to establish a BT connection between two systems. The client is running bluez-5.14 and I'm using bluetoothctl to interface with the daemon. The server system provides a NAP, plus dnsmasq, so that connecting clients receive an IP. For reference, this works perfectly on an Android smartphone. When connecting to the server system, the bnep device is created on the server and added to the bridge. The Android bluetooth stack then gets an IP via dnsmasq and voila... TCP/IP connection. On this client however, this doesn't work at all. Plus, I'm not getting any kind of meaningful error message. That's the server: [bluetooth]# info 00:02:72:C6:43:11 Device 00:02:72:C6:43:11 Name: chidori-bt Alias: chidori-bt Class: 0x020000 Paired: yes Trusted: yes Blocked: no Connected: no LegacyPairing: no UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb) UUID: NAP (00001116-0000-1000-8000-00805f9b34fb) UUID: PnP Information (00001200-0000-1000-8000-00805f9b34fb) UUID: Generic Access Profile (00001800-0000-1000-8000-00805f9b34fb) UUID: Generic Attribute Profile (00001801-0000-1000-8000-00805f9b34fb) Modalias: usb:v1D6Bp0246d0509 And here's how connecting goes: [bluetooth]# connect 00:02:72:C6:43:11 Attempting to connect to 00:02:72:C6:43:11 [CHG] Device 00:02:72:C6:43:11 Connected: yes [CHG] Device 00:02:72:C6:43:11 Modalias: usb:v1D6Bp0246d0509 Failed to connect: org.bluez.Error.NotAvailable [CHG] Device 00:02:72:C6:43:11 Connected: no So, it looks like that it briefly connect, but then drops the connection again. I haven't been able to figure out what exaclty is 'NotAvailable' at this moment. The server at least is. This is something from the bt daemon (client): leena bluetoothd[26910]: Bluetooth daemon 5.14 leena bluetoothd[26910]: Starting SDP server leena bluetoothd[26910]: Bluetooth management interface 1.3 initialized leena bluetoothd[26910]: Sap driver initialization failed. leena bluetoothd[26910]: sap-server: Operation not permitted (1) leena bluetoothd[26910]: Can't add /org/bluez/hci0/dev_00_02_72_C6_43_11 to non-LE capable adapter connect list I'm not sure if the 'non-LE' message has something to do with the issue. Any idea on how to proceed here?
