I'm having trouble learning a command from another remote.
First, be sure that the remote you are learning from has fresh batteries. Also, use Griffin's Utility App to make sure your Beacon has the most up-to-date firmware available.
Next, position Beacon and your original device remote control as shown in the diagram below.
Your remote should be touching the plastic stone, not the base, of Beacon. When you see a pulsing button in Dijit and blinking blue light on Beacon, press the corresponding button on your remote control to teach it to Dijit. After Dijit learns the button, it will automatically move on to the next button.
