A "daemon" constantly trying to enable ADB tcpip on any connected device

adbtcpipd

#!/usr/bin/env bash

sleep 5

if /sbin/ifconfig usb0 &>/dev/null; then
	# usb0 is present - we are in slave mode, this script won't work.
	exit
fi

led() {
	local brightness=0
	[ "$1" -eq 0 ] && brightness=1
	echo "$brightness" >/sys/class/leds/LED/brightness
}

/sbin/modprobe -r ledtrig_heartbeat

while :; do
	if adb tcpip 5554 &>/dev/null; then
		led 1
		sleep 10
	else
		led 0
		sleep 2
	fi
done
