 **IMPORTANT**: Only one TCP connection can be in use with a device at once. If testing this, do not have the app on your phone open.
 
 ## TODO
 
 3.  Better documentation.
-4.  Support arbitrary control schemes for devices as self-reported.
-5.  Use Promises for all functions?
 7.  Add automated tests
 8.  Document details of protocol
+9.  Add error message for no IP
