Hi Danis, I rebuild my bluez again without "--enable-pnat" in bootstrap-configure. Now, my sdp result shows ONLY ONE "Dial-up Networking" service. It is from ofonod. Retest this case. It reports "Security block" after DUN server gets "Dial-up Networking" record. The hcidump will be attached in bug --- https://bugs.meego.com/show_bug.cgi?id=25303 . At this time, I tried a FTP case (to prove pairing is OK), FTP passed. So, I suspect DUN response "security block" may be due to DUN service itself, which is provided by ofonod. Please help to check it.

However, the problem is my DUN activation request almost did not come to ofono side (only to bluez RFCOMM). On the DUN Client, I can use same validation step to active a mobile phone (Sony-Ericson C905) to connect to 2G/3G network. > > I filed a bug https://bugs.meego.com/show_bug.cgi?id=25303 to track all logs. > > Could you help to see what's the problem? > > Thanks > Jingke > -- > To unsubscribe from this list: send the line "unsubscribe > linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > Your hcidump shows 2 SDP records for DUN profile. Guillaume Zajac and I found the same problem yesterday, and reply about it on oFono mailing list (see "Re: oFono DUN server issue" mails). It seems that BlueZ was compiled with embedded DUN server (configure option --enable-pnat). When both BlueZ and oFono are started, they both listen for incoming connection on RFCOMM port 1 (try "sdptool browse local" to check), and embedded BlueZ DUN server reply preventing oFono to manage this connection. If you remove the embedded DUN server by removing --enable-pnat from build configuration, it should work.
