 ### 3. Create the Bluetooth® Low Energy Sketch
 
-Let's program the Portenta with the following example sketch. If the Bluetooth® Low Energy module can be initialized correctly, you will see the blue LED lighting up for one second after uploading the sketch. If it fails you will see the red LED lighting up instead.
