Hello!
I try to follow some instructions from [1] to connect my gentoo box (client role) to rasberry-pi box (server role).
I have already paired and marked "trusted" the related sides.
But when I try to connect to rasberry-pi via test-network (shipped in sources of bluez-5.25) I got the following error message:
| Code: |
/test-network 00:1A:7D:0A:BC:75
Traceback (most recent call last):
File "./test-network", line 42, in <module>
iface = network.Connect(service)
File "/usr/lib64/python2.7/site-packages/dbus/proxies.py", line 70, in __call__
return self._proxy_method(*args, **keywords)
File "/usr/lib64/python2.7/site-packages/dbus/proxies.py", line 145, in __call__
**keywords)
File "/usr/lib64/python2.7/site-packages/dbus/connection.py", line 651, in call_blocking
message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "Connect" with signature "s" on interface "org.bluez.Network1" doesn't exist
|
The bnep0 local network interface isn't crated. As far as I can understand it even does not tries to connect. What should I do?

Thanks for any help!

Hi, I'm also using the NAP setup from mentioned wiki. Since Bluez5 and/or recent /etc/init.d/bluetooth, I have to initialize the device to make it work.
| Code: | # hciconfig
hci0: Type: BR/EDR Bus: USB
BD Address: 00:09:DD:XX:XX:XX ACL MTU: 310:10 SCO MTU: 64:8
DOWN
RX bytes:537 acl:0 sco:0 events:24 errors:0
TX bytes:329 acl:0 sco:0 commands:22 errors:0
# hciconfig hci0 up
# hciconfig
hci0: Type: BR/EDR Bus: USB
BD Address: 00:09:DD:XX:XX:XX ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN
RX bytes:1056 acl:0 sco:0 events:49 errors:0
TX bytes:917 acl:0 sco:0 commands:47 errors:0

Maybe this is the issue on your rasberry-pi (or gentoo box). From a desktop, applications like BlueDevil will do that automatically. This seems new behaviour according to this bug report.
I can't tell anything from the client roll perspective. I'm using the setup to connect an old cell phone to the network. Apps like Opera Mini and MidpSSH initiate the network connection. The phone is not rooted, so I can't test anything there. |

Finally I have managed to find the solution.
Here is an original link http://www.xnos.org/linux/blue-linux/hardware/compaq-ipaq/rfcommppp-connection.html
I'm going to duplicate here - it might be useful for somebody if original page is gone. I assume the devices are already paired.
On gentoo box (server side):
| Code: |
rfcomm listen /dev/rfcomm0 5 (on 1st terminal)
pppd /dev/rfcomm0 115200 192.168.201.1:192.168.201.2 noauth nodetach (on another terminal).
|
That could be shortened to:
| Code: |
rfcomm watch /dev/rfcomm0 5 pppd /dev/rfcomm0 115200 192.168.201.1:192.168.201.2 noauth nodetach
|
On raspberry-pi box (client-side)
| Code: |
rfcomm connect /dev/bluetooth/rfcomm/0 00:A0:96:1F:21:81 5 (on 1st terminal)
pppd /dev/rfcomm0 115200 192.168.201.2:192.168.201.1 noauth nodetach
|
I've spent hours on determining how to do that with DUN/BNEP/PAN etc.; but I haven't found any reasonable solution. That's one is rather simple and useful for me.

DMoL,
That's a brilliant way to have an extra NIC. 
The speed is not bad. Could be around 1.5 Mbps with Bluetooth v2.
Cheers! |
