@em1lio189 La libreria che sto usando è TinyGPS.h.
@Gugliemo: per aumentare il buffer di ricezione devo crearmi un array di char? Una cosa del tipo:
char incomingSms[128] = {'\0'};
for (int i = 0; i < 128; i++)
{
incomingSms[i] = gsmSerial.read();
}
Ora che mi viene in mente, mettendo un print su gsmSerial.available() questo mi ritorna 1, che è il primo carattare che vedo a video, invece che la lunghezza esatta.
Non so se ci sono altri problemi comunque posto il codice completo.
