Hi Luiz, I've managed to narrow things down a little bit: The Exception occurs with bluez 5.35 *and* 5.36 if i deliberately turn an interface off which is already powerd down. This power-down works some 3 - 5 times without any problems and then causes this exception after blocking some 10 seconds. Here are my configure and startup parameters: ./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --disable-systemd --enable-experimental ./bluetoothd -E -n -d As a workaround I read the power state before writing anything, but I really think this should behave deterministic ;-) cheers, Matthias Senior Systemarchitekt Netpioneer GmbH, Ludwig-Erhard-Allee 20, 76131 Karlsruhe Geschäftsführer: Axel Jahn HRB: 107521 Handelsregister Mannheim Tel: 0721 / 9 20 60 822 Fax: 0721 / 9 20 60 30 E-Mail: matthias.schmidt@xxxxxxxxxxxxx www: http://www.netpioneer.de ________________________________________ Von: Luiz Augusto von Dentz [luiz.dentz@xxxxxxxxx] Gesendet: Montag, 30.

Btw the signature of org.freedesktop.DBus.Properties is "ssv" so perhaps that is the problem. > I'm running Linux 4.1.2 on armv7l > > Is there any chance to nail this down? > > cheers, > > Matthias > > Senior Systemarchitekt > Netpioneer GmbH, Ludwig-Erhard-Allee 20, 76131 Karlsruhe > Geschäftsführer: Axel Jahn > HRB: 107521 Handelsregister Mannheim > > Tel: 0721 / 9 20 60 822 > Fax: 0721 / 9 20 60 30 > E-Mail: matthias.schmidt@xxxxxxxxxxxxx > www: http://www.netpioneer.de > -- > 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 -- Luiz Augusto von Dentz -- 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
