Buonasera, Vorrei un aiuto per capire come mai il codice non fa ciò che voglio. Più In particolare in questo esempio uso un' arduino portenta h7 che funge da server con un imu bno055 attaccato.
Sostanzialmente il problema dovrebbe essere banale. Infatti lo stesso codice, l ho creato con comunicazione bluetooth: usando un'app come client, premendo il tasto per rendere lo stato readacc=1, riesco a leggere in realtime come variano i dati che voglio leggere (fin quando non premo il tasto che rendo readacc=0). Se uso la comunicazione wifi la stessa logica non vale. Infatti premo il tasto per rendere lo stato readacc=1 e solo una riga viene restituita come output. Non capisco se sto sbagliando qualcosa nella lettura dello stato oppure altro.

Quindi premi CTRL-T copia la funzione loop e postala nuovamente, se è identata correttamente io posterò la funzione loop modificata che fa quello che desideri.
