[Bluez-devel] Serial server problems

[Bluez-devel] Serial server problems

[Pooyan McSporran]

(I'm unclear on which list, either bluez-devel or bluez-users, this
query should be on.  Let me know if I've sent to the wrong list.)

I'm trying to write an application using BlueZ which will:
- advertise a service, based on SPP (custom UUID, etc)
- listen for incoming connections for that service
- when an inbound connection is requested, create the connection
- send data to/from on the connection

I'm having problems trying to work out how to do this using the DBus
interface.  I've browsed through the Wiki (http://wiki.bluez.org) but
all the examples that I've found seem to be from the client
perspective, not a server.  (Correct me if I'm wrong.)  The only
server example I found is for the network service, not the serial
service.  Similarly, the 'test-serial' python script only implements a
client.

The approximate sequence of actions that I'm currently
(unsuccessfully!) using is:
- Determine the default adapter (DefaultAdapter())
- add the service (AddServiceRecordFromXML())
- activate the serial service (ActivateService ("serial"))

The service is then visible to remote devices (so far so good!)

- create a proxy (serial.Manager.CreateProxy (uuid, "/dev/rfcomm0"))

This is where I'm obviously missing some basic stuff, I'm not sure in
this area (with ports, proxies, etc).  Any help that people might have
in this regard would be appreciated.

Thank you.

Hi Pooyan,

The address is wrong. Here are some examples:
TTY proxy: "/dev/ttyS0"
Unix socket: "/tmp/gps-data"
Unix socket(abstract namespace): "x00/org/bluez/echo"

I will try update the BlueZ wiki with some unix socket proxy examples.

BR,
Claudio.

Thanks, I'd appreciate that.

For now I'm using DBus to do everything else (eg setting the name of
the adapter, making it visible, advertising the service via SDP, etc),
but using sockets for the serial aspects, but in the longer term I'd
like to use DBus for everything, so that wiki information would be
helpful.

[Bluez-devel] Serial server problems

[Pooyan McSporran]

(I'm unclear on which list, either bluez-devel or bluez-users, this
query should be on.  Let me know if I've sent to the wrong list.
Also, I'm having some erratic email issues, so my apologies if this
appears twice.)

I'm trying to write an application using BlueZ which will:
- advertise a service, based on SPP (custom UUID, etc)
- listen for incoming connections for that service
- when an inbound connection is requested, create the connection
- send data to/from on the connection

I'm having problems trying to work out how to do this using the DBus
interface.  I've browsed through the Wiki (http://wiki.bluez.org) but
all the examples that I've found seem to be from the client
perspective, not a server.  (Correct me if I'm wrong.)  The only
server example I found is for the network service, not the serial
service.  Similarly, the 'test-serial' python script only implements a
client.

The approximate sequence of actions that I'm currently
(unsuccessfully!) using is:
- Determine the default adapter (DefaultAdapter())
- add the service (AddServiceRecordFromXML())
- activate the serial service (ActivateService ("serial"))

The service is then visible to remote devices (so far so good!)

- create a proxy (serial.Manager.CreateProxy (uuid, "/dev/rfcomm0"))
- Enable the proxy (proxy.Enable ())

This is where I'm obviously missing some basic stuff, I'm not sure in
this area (with ports, proxies, etc).  In this scenario I end up with
'invalid address' on the CreateProxy() call.  Looking at the API,
CreateProxy expects either a socket or a character device, but I'm
unsure what I should use here in my scenario.  Should I be using
rfcomm0 in this manner, or some other approach?  Any help would be
appreciated.

Thanks.

simply use the RFCOMM socket interface and use D-Bus only for
registering the SDP record.

Regards

Marcel

Thanks for your help.  I'm now using this approach and it is working well.
