Handle multiple server.connect() calls code snippet

// Define the function that will be called when the device has connected
// to the server (or the connection attempt times out)

	if (reason == SERVER_CONNECTED)
	{
		// Server is online. Because we can't say which sensor
		// triggered the server.connect() we check both trigger
		// flags so both cases are handled. If only one sensor
		// triggers the callback, that works too.
