My laptop runs ubuntu 16.04. Linux: 4.4.0-93-generic I tried to debug this issue by compiling bluetoothd from source code. Surprisingly, this issue is fixed after executing newly compiled bluetoothd instead of /usr/lib/bluetooth/bluetoothd. Steps to build and run newly compiled bluetoothd is listed below.
sudo systemctl disable bluetooth.service sudo systemctl stop bluetooth.service * make sure bluetoothd started by systemd is stopped. sudo systemctl status bluetooth.service * build bluetoothd mkdir test cd test/ apt-get source bluez cd bluez-5.37/ sudo apt-get install libglib2.0-dev sudo apt-get install libdbus-1-dev sudo apt-get install libudev-dev sudo apt-get install libical-dev sudo apt-get install lib64readline-dev sudo apt-get install libreadline-dev ./configure make cd src/ ls sudo ./bluetoothd -n bluetooth may work now. The drawback is that you have to start bluetoothd manually after reboot. Good luck. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1490349 Title: 15:10 and 16.04: bluetoothd "Failed to start discovery: org.bluez.Error.NotReady" after bluetoothd restarted Status in bluez package in Ubuntu: Invalid Bug description: On 15:10 after the bluetooth service has been stopped and restarted it is not possible to scan or connect to devices: $ sudo systemctl restart bluetooth $ bluetoothctl [NEW] Controller 00:1F:3A:E0:0A:AF hephaestion.lan.iam.tj [default] [NEW] Device 00:0A:95:4B:BD:C2 Apple Wireless Keyboard [NEW] Device 00:07:61:3B:86:98 Bluetooth Travel Mouse [bluetooth]# scan on Failed to start discovery: org.bluez.Error.NotReady To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1490349/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
