cat app.go will get:

package main
import (
// Handler will handle the raw bytes of data
func Handler(data []byte) (frame.Tag, []byte) {
	fmt.Printf("sfn received %d bytes\n", len(data))
	output := strings.ToUpper(string(data))
	return frame.Tag(0x34), []byte(output)
// DataTags indicate the tags of data to observe
func DataTags() []frame.Tag {
	return []frame.Tag{0x33}

Now, just execute yomo dev, it works!
