If your EV3 Brick is not listed in the “Select An EV3 Brick” dialog box, please make sure Bluetooth is enabled and visible on your EV3 Brick and that you have unchecked the iPhone/iPad/iPod mode as shown below.

If your EV3 Brick still does not appear in the “Select An EV3 Brick” dialog box, try to connect your EV3 Brick from your device by using the following steps:

Go to Settings >> Bluetooth >> Show Bluetooth Devices
Make sure Bluetooth is turned on and search for a minute, or until your EV3 Brick is listed under Bluetooth Devices
”When your EV3 brick appears and writes ’ready to pair’ you should click ’pair’
A “Connect? (name of your device)” dialog box will appear on your EV3 Brick >> Accept >> A “PASSKEY” dialog box will appear on your EV3 Brick >> accept >> Enter the passcode on your device and click “Next” and it is connected

You can now go back to the EV3 Program Available Bricks >> Connect >> “Select An EV3 Brick” dialog box and click on the device.

If there are troubles connecting to Bluetooth the user should go to the native settings (settings of the tablet) and then remove the device (EV3) and reconnect.
