BT PAN Connection - NAP with PANU ?

BT PAN Connection - NAP with PANU ?

[Ajay Parashar]

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.

I searched a lot but did not get any example, script  or command that
can let me know how to execute PANU.

It will be great help if you please let me know how can i start PANU
and communicate it with NAP.

Regards
Ajay

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")

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,

Hi,

I reached till here and yes after executing test-network it gives
error.

signature "s" on interface "org.bluez.Network1" doesn't exist"

Please let me know is there any way to resolve this
issue?
Pasting Error details as below:

Hi,

I nail down the issue why it always says (UnknownMethod: Method
"Connect" with signature "s" on interface "org.bluez.Network1" doesn't
exist).

While debugging more,  it sounds that /org/bluez/hci1 provides only 8
interfaces.(org.bluez.Adapter1, CyclingSpeedManager1,
HeartRateManager1, Media1, NetworkServer1, ThermometerManager1,
DBus.Introspectable, DBus.properties).

org.bluez.Network1 interface entry is missing from /org/bluez/hci1 ?

For your reference i am attaching snapshot of my set up, please let me
know how can i add org.bluez.Network1 interface with /org/bluez/hci ?
Is there any configuration file that i need to change ? or any other
way to achieve this goal?

Regards
Ajay

Hi Bharat,

I hope this issue has resolve at your end?

i did the change as suggested by you but it did not resolve the issue.
For your reference i am attaching bluetooth.conf with my change at
line number 21,  can you please confirm is this the only change
required ? or some more changes need to do ?

I have 1 more question the interfaces name mentioned in
bluetooth.conf does not match with my set up. Again i am attaching
snapshot of my setup.

Please let me know how this issue can be resolved at my end ?

Regards
Ajay

Usage: ./test-network <address> [service]

There should be a device object for the given address and it must
implement org.bluez.Network1 interface, if that doesn't exist than it
is probably due to missing SDP record.

Hi Luiz,

Thanks a lot for pointing  the right direction.
Issue was bad sequence of steps execution, i was doing pairing first
and then executing NAP server.

Now first i am executing NAP server and then pairing, so that both
devices have knowledge of NAP service.
I confirmed that this issue has resolved @ my end.

Thanks & Regards
