Hi,

I am using bluez 5.35 and performing one POC with NAP and PANU communication.
I want to connect PANU with NAP, for this i executed below tasks

1) Created a bridge successfully with Ubuntu 15.10.
2) Executed /test/test-nap script and i can see that NAP has established.

3) I am not getting how to start PANU (client) so that it can be
connected with NAP (as defined in above step 2) and start
communicating each other.

How about doc/network-api.txt:

https://git.kernel.org/cgit/bluetooth/bluez.git/tree/doc/network-api.txt

e.g: org.bluez.Network1.Connect("panu")

My fault i did Top posting, so giving my reply again in right format.

Hi,

Thanks for reply, I will try this connect API.
In my case it need to be connected with NAP as PANU itself, so the
parameter of connect api  should states its own role or the role of
server with whom it needs to be connected?

These APIs are used in python examples, is there similar API available
for C programming application also?
Can i get similar C example ?

It is actually a D-Bus method call so any D-Bus binding would do it,
we just did in python because it is much more convenient.

HI Luiz,

I will try with C language D-Bus binding.

Prior to this I tried to execute bluez-5.34/test/test-network example
and i m getting below error.
 1) It sounds me that it is unable to found Bluetooth device, but my
device is quite ready and working with other examples."
2) other reason could me i did not pair this with /test-nap example,
should first i pair this test-network example device with test-nap
example device ?

Can you please let me know why i am getting this error or let me know
some pointers from where i can debug this issue.

Traceback (most recent call last):
  File "./test-network", line 41, in <module>
    device = bluezutils.find_device(args[0], options.dev_id)
  File "/mnt/hgfs/shared_With_VM_Ubuntu/test/bluezutils.py", line 30,
in find_device
    adapter_pattern)
  File "/mnt/hgfs/shared_With_VM_Ubuntu/test/bluezutils.py", line 47,
in find_device_in_objects
    raise Exception("Bluetooth device not found")
Exception: Bluetooth device not found

The test-network script, tries to search for remote device in device
databases. So for this you first need to add the device in devices
list by successfully pairing to the device from bluetoothctl. If
bluetoothctl lists the remote device name for "devices" command, then
this will not show this error anymore.
Then you will encounter another error i.e "No such method "Connect"
with signature "s" exists on org.bluez.Network1 interface". I am not
sure how to get rid of this now.
