Hi,
I experiment this issue with two different machines, issue still persists.
Please let me know how can i unblock from this issue, i will be
thankful you guys.
Let me explain the steps followed.
On Machine 1
Step 1)
# hciconfig
hci1: Type: BR/EDR Bus: USB
BD Address: 00:1A:7D:DA:71:05 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN INQUIRY
\RX bytes:43793 acl:12 sco:0 events:353 errors:0
TX bytes:2641 acl:11 sco:0 commands:130 errors:0
Step 2)
create a bridge using brctl commands and it is very much visible and
verified the same by ifconfig command.
# ifconfig
br0 Link encap:Ethernet HWaddr b6:a3:07:14:05:73
inet addr:10.0.10.1 Bcast:0.0.0.0 Mask:255.255.255.0
inet6 addr: fe80::b4a3:7ff:fe14:573/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:215 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:22135 (22.1 KB)
Step 3)
paired this controller successfully with other BT controller that is
associated with machine 2
Step 4)
verified pair status from both machines.
Step 5)
execute the test-nap program
./test-nap br0
Server for nap registered for br0
Press CTRL-C to disconnect
step 6)
On machine 2 verify that controller is working by hciconfig command
# hciconfig
hci0: Type: BR/EDR Bus: USB
BD Address: 00:1A:7D:DA:71:07 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:1488 acl:12 sco:0 events:83 errors:0
TX bytes:3609 acl:13 sco:0 commands:56 errors:0
step 7)
On machine 2 execute test-network program
./test-network 00:1A:7D:DA:71:05 nap
Traceback (most recent call last):
File "./test-network", line 48, in <module>
iface = network.Connect(service)

dbus.exceptions.DBusException:
org.freedesktop.DBus.Error.UnknownMethod: Method "Connect" with
signature "s" on interface "org.bluez.Network1" doesn't exist
