shell script for adb wifi

adbwifi.sh

#!/bin/bash
   
#Modify this with your IP range
MY_IP_RANGE="192\.168\.1"

#You usually wouldn't have to modify this
PORT_BASE=5555

#List the devices on the screen for your viewing pleasure
adb devices
echo

#Find USB devices only (no emulators, genymotion or connected devices
declare -a deviceArray=(`adb devices -l | grep -v emulator | grep -v vbox | grep -v "${MY_IP_RANGE}" | grep " device " | awk '{print $1}'`)  

echo "found ${#deviceArray[@]} device(s)"
echo

for index in ${!deviceArray[*]}
do
echo "finding IP address for device ${deviceArray[index]}"
IP_ADDRESS=$(adb -s ${deviceArray[index]} shell ifconfig wlan0 | awk '{print $3}')

echo "IP address found : $IP_ADDRESS "

echo "Connecting..."
adb -s ${deviceArray[index]} tcpip $(($PORT_BASE + $index))
adb -s ${deviceArray[index]} connect "$IP_ADDRESS:$(($PORT_BASE + $index))"

echo
echo
done

adb devices -l
#exit

This does not work for Moto G either.

The last two lines of the output show unauthorized:

...
List of devices attached 
192.168.6.110:5555     unauthorized

finding IP address for device 47Q6R16328002931
IP address found : 172.18.214.94
Connecting...

right ?

good

I updated your script to consider netcfg, ifconfig and currently connected ports: https://gist.github.com/akidee/04ade213c92f087b06920698190f71b5

Having reached this gist from Google, I adapted it for my needs.
In particular, the command in line 22 to find the IP failed for me on Android 10 due to a permission error. I suspect something changed that made ifconfig require elevated rights. With this solution from StackOverflow, I was able to get the script running by changing that line to this:

IP_ADDRESS=$(adb -s ${deviceArray[index]} shell "ip addr show wlan0 | grep -e wlan0$ | cut -d\" \" -f 6 | cut -d/ -f 1")

Also, I'd like to thank you for introducing me to the declare/array syntax, which I had never used before!
