docs: Send one-or-more key-value pairs to the watch-app identified by the provided UUID. This is the primary method for
  sending data from the phone to a connected Pebble.
  
  The watch-app and phone-app must agree of the set and type of key-value pairs being exchanged. Type mismatches or
  missing keys will cause errors on the receiver's end.
  
  @param context
  The context used to send the broadcast.
  @param watchappUuid
  A UUID uniquely identifying the target application. UUIDs for the stock kit applications are available in
  {@link Constants}.
  @param data
  A dictionary containing one-or-more key-value pairs. For more information about the types of data that
  can be stored, see {@link PebbleDictionary}.
  
  @throws IllegalArgumentException
  Thrown in the specified PebbleDictionary or UUID is invalid.
