Afficher retour console Arduino dans un TextView Besoin d'aide.

Bonjour j'ai essayé de créer un application android pour piloter des strips led, j'ai récupéré un projet Android studio que j'ai modifié pour arriver a mes fins.
Ce qui marche plutôt bien.
J'aimerais pouvoir afficher ce que me retourne la console d'un arduino nano dans un textView

Code:

---

1 2	TextView textViewData=findViewById(R.id.TextViewData); textViewData.setText(Reception);

---

mais tous mes essais d'inclure un code avec InputStream inputStream; ne fonctionnent pas, l'application plante ou fige.

Quelqu'un pourrait il m'aider car je n'ai aucune connaissance en Java j'ai réussi à faire cela avec de l'intuition et surement beaucoup de chance.

d'avance merci.
