Re: [Bluez-devel] Problems with sdp_connect()

[Marcel Holtmann <marcel@holtmann.org>]

Hi,

> I am writing my thesis on Bluetooth programming under Linux and I would be grateful to you if you could give me hints to solve this problem. I have two bt devices on my laptop, both of them run the same program and register the same SDP service. When I register the service I call sdp_connect(&src, BDADDR_LOCAL, RETRY_IF_BUSY). It works but when I try to search the service from a device outside my laptop I discover the same service twice for each device. Resuming:
> - Bluetooth device A register a service C on my laptop --- sdp_connect(&srcA, BDADDR_LOCAL, ...) 
> - Bluetooth device B register a service C on my laptop --- sdp_connect(&srcB, BDADDR_LOCAL, ...)
> - Searching service C on device A will find it twice instead of once

> I thought the problem was in BDADDR_LOCAL, which is defined as {0, 0, 0, 0xff, 0xff, 0xff} but if I try to register the service connecting with SDP server as sdp_connect(&srcA, &srcA, ...) it returns error "Host is down". I don't know where to hurt my head...

use the latest bluez-libs package and then you can register per device
services. Look at sdp_device_* functions or use the -i switch of
sdptool.
