 If you prefer to use one communication technology over the other, then this can be changed with the simple use of one sketch. Open the **ChoseRadioAccessTechnology** sketch located in the **MKRNB** examples. When this sketch is uploaded, open the serial monitor. You will now get options for what technology you prefer to use in the serial monitor. Follow the steps and wait for the sketch to say that it is finished. The board will now use the preferred technology and we can move on to upload other sketches.
