Connecting to wi-fi using adb shell

I have all the details to connect to a particular access point. I have to use that access point only, so all I require is the command to do it.


You can add a network entry into the wpa_supplicant.conf yourself (or within your script) Essentially connect manually once, then do:

adb pull /data/misc/wifi/wpa_supplicant.conf

and integrate the network entry into your script for automation. Example simple script:


# Get this information by connecting manually once, and do
#   adb pull /data/misc/wifi/wpa_supplicant.conf
ADB_PULL="adb pull /data/misc/wifi/wpa_supplicant.conf"

adb start-server
adb wait-for-device
echo "adb connection....[CONNECTED]"
adb root
adb wait-for-device
adb remount
adb wait-for-device

pushd /tmp
rm wpa_supplicant.conf 2>/dev/null # Remove any old one
adbpull_status=`$ADB_PULL 2>&1`
echo -e "\nAttempting: $ADB_PULL"
if [ `echo $adbpull_status | grep -wc "does not exist"` -gt 0 ]; then
    echo "  wpa_supplicant.conf does not exist yet on your device yet."
    echo "This means you have not used your wireless yet."
    echo ""
    echo "Taking our best shot at creating this file with default config.."

    echo "ctrl_interface=$WIRELESS_CTRL_INTERFACE" >> wpa_supplicant.conf
    echo "update_config=1" >> wpa_supplicant.conf
    echo "device_type=0-00000000-0" >> wpa_supplicant.conf
    echo $adbpull_status
    echo "  wpa_supplicant.conf exists!"

echo ""
echo "Add network entry for wpa_supplicant.conf.."
echo "" >> wpa_supplicant.conf
echo "network={" >> wpa_supplicant.conf
echo "  ssid=\"$WIRELESS_SSID\"" >> wpa_supplicant.conf
echo "  key_mgmt=$WIRELESS_KEY_MGMT" >> wpa_supplicant.conf
echo "  eap=$WIRELESS_EAP" >> wpa_supplicant.conf
echo "  identity=\"$WIRELESS_USER\"" >> wpa_supplicant.conf
echo "  password=\"$WIRELESS_PASSWORD\"" >> wpa_supplicant.conf
echo "  priority=1" >> wpa_supplicant.conf
echo "}" >> wpa_supplicant.conf
echo "Pushing wpa_supplicant.conf.."
adb push wpa_supplicant.conf /data/misc/wifi/wpa_supplicant.conf
popd #/tmp

adb shell chown system.wifi /data/misc/wifi/wpa_supplicant.conf
adb shell chmod 660 /data/misc/wifi/wpa_supplicant.conf

echo ""
echo "Finished!"
adb shell am start -a android.intent.action.MAIN -n
echo "Please toggle wifi off/on now.. (ifconfig not sufficient, monkey this)"
