Connecting with App-based VEXcode 123 - Android

It takes just a few steps to connect a 123 Robot to your Android device.

Turn on the 123 Robot by pushing the 123 Robot along a surface to “wake” it.


Launch VEXcode 123.


Open VEXcode 123 and select the Robot icon in the Toolbar.


Select ‘Connect.’


When selecting ‘Connect,’ you may receive a prompt asking to verify access. Select ‘Allow.’


A list of available 123 Robots will appear. Select the name of the Robot you want to connect to.


Once a Robot is chosen, select the ‘Connect’ button.


The Robot icon will turn orange and a ‘Connecting to:’ message will appear while the Robot is connecting.


Once the 123 Robot is connected, the icon will turn green. The message in the window will say ‘Connected to:’ and list the name of the 123 Robot that is connected to this Android device.


Underneath the 'Connected to:' message, there is an icon that displays the battery level of the 123 Robot.

The level in the battery will appear as one of three colors:


Red for a low battery level
