Hi, Marcel
I tried the bluetooth-wizard in bluez-gnome-1.8 to connect local bluetooth
device with another one, and connected successfully. But when I run the script
"./test/connect-network dev_00_xx_xx_xx_xx_xx", got the error information as
below:
Connecting: /hci0/dev_00_xx_xx_xx_xx_xx
Traceback (most recent call last):
File "./connect-network", line 43, in <module>
network.Connect()
File "var/lib/python-support/python2.5/dbus/proxies.py", line 140, in __call__
** keywords)
File "var/lib/python-support/python2.5/dbus/connection.py", line 607, in
call_blocking
message, timeout)
Dbus.exceptions.DBusException: org.moblin.connman.Error.Failed:
When try test-device in bluez-4.22, got the same result.
The dev_00_xx_xx_xx_xx_xx is the bluetooth dungle on my desktop.
So still fail to connect to other bluetooth device, any comments?
