Returned an error when an address is malformed

[oliviermartin]

I was informed by email that gattlib fails with the assertion: (process:1191): GLib-GIO-CRITICAL **: g_dbus_connection_signal_subscribe: assertion 'object_path == NULL || g_variant_is_object_path (object_path)' failed ... when the address is malformed. In this case, there was a space before the address in the string.

When I use the comannd: ./discover fc:d6:bd:10:19:2a I have this failure: "Device connected error: GDBus.Error:org.freedesktop.DBus.Error.UnknownObject: Method "Connect" with signature "" on interface "org.bluez.Device1" doesn't exist

Fail to connect to the bluetooth device." When I use the command: ./discover FC:D6:BD:10:19:2A, there is no error and the connections is successful.

For me, letter case does not seem to matter. I get the same error as @Azkom even when I run ./discover FC:D6:BD:10:19:2A (yes, same MAC as he used). ./ble_scan lists my devices correctly.

Compiled and run on Raspbian Stretch

Hi @mamert, could you try again? I have made few changes/fixes today in gattlib. I still believe the issue exists but who knows (I saw a similar issue when trying to connect to many devices one after the other one).

@oliviermartin I'm afraid I can only add to the confusion, and I apologize if I had missed something obvious... before pulling your changes today, I reset everything to defaults and tested again... and the old version worked. ./discover successfully connected to my device (the BT device now won't connect with my phone, but that's a different matter). On the other hand, ./discover FC:D6:BD:10:19:2A (a MAC that doesn't exist here) still throws the same "method doesn't exist" error, even after using the updated gattlib. So, I guess it actually meant "device not found"? But the device doesn't need to be on, only paired (stored in /var/lib/bluetooth/{adaptermac}/) for there to be no error. If the device is on but not paired, we get the error. Curiously, sudo l2ping gives "can't connect: Host is down" when ./discover works fine.
