I have been experimenting with pinging a list of known Bluetooth MAC addresses for a tracking project with a Pi 3, however, the ping does not seem to time out until after 5-7 seconds if there is no device detected. In contrast if there is a device it will only take around 1 second before it moves on. Even with -t there seems to be no overriding it.
sudo l2ping -c 1 -t 1 xx:xx:xx:xx:xx:xx
Is there any way to force a faster timeout?
EDIT: Corrected flag order
