Thanks in advance.

A home-owner wishes to improve the security of their home. They decide to arm their doors and windows with a sensor that, when tripped, makes a phone call to the home owner. The sensors are connected to the DragonBoard™ 410c through the GPIO pins. However, the program the home-owner wrote isn't making the phone call.

Out of the follow choices, what things should the home-owner do or check (with regards to the program)?


1. Check if the signals from the sensors are being received properly.


2. Check if the SipProfile is being created and registered properly.


3. Check if the GPIOs are working correctly.


4. Check if the strings are in the correct places.


5. Check for syntax errors.
