[SOLVED] Intel 7260 bluetooth keeps disconnecting

Hello,

I've been having issues with bluetooth connectivity where the connection disconnects periodically.  It looks like the rfkill service is shutting it down for some reason, and a journalctl snapshot is below.  Has anyone dealt with this before?  Is rfkill something that I can disable?

It looks like the rfkill was coming from the TLP package.  I removed TLP, and it looks like the issue may be solved.

Re: [SOLVED] Intel 7260 bluetooth keeps disconnecting

Instead of removing the TLP package, there is a setting

# Exclude bluetooth devices from autosuspend mode to
# solve stability issues with bluetooth connections:
USB_BLACKLIST_BTUSB=1

in /etc/tlp.conf that could solve the issue as well.
