καλησπερα σας, προσπαθώ να σύνδεσω εδω και λίγο καιρό το ADAFRUIT BLUEFRUIT LE με μία συσκευή polar για να παίρνω μέσω bluetooth τα δεδομένα στο adafruit υπάρχει ένας έτοιμος κώδικας αλλα δεν ξέρω το πρέπει να αλλαξω ακριβως για να συνδεσω το polar.Κώδικας:/********************************************************************* This is an example for our nRF51822 based Bluefruit LE modules Pick one up today in the adafruit shop!
