That seems to be the real problem here, check what is the log of bluetoothd perhaps is not working properly because you are running gatttool. > > One post suggested that bluez does not support BLE without a configuration change using btmgmt le on, but that fails > "Set Low Energy for hci0 failed with status 0x11 (Invalid Index)", presumably as bluetoothd has no controller. Thats not bluetoothd, actually the kernel mgmt interface is used so even the kernel is not able to work, perhaps something is interfering with the setup or setting it up to use a user channel mode. > Any pointers as to what I am missing (bluetooth newbie) > > Thanks, > Stu > > > > > > -- > 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
