Bidirectional Communication with Collision Avoidance Since SoftwareSerial is half-duplex, implement a simple protocol: // Switch back void setup() Serial.begin(9600)

void checkForData(SoftwareSerial &ss) ss.listen(); if (ss.available()) // Process // Debug console gps.begin(9600)

SoftwareSerial port1(2, 3); SoftwareSerial port2(4, 5); void setup() port1.begin(9600); port2.begin(9600); port1.listen(); // port1 is active

void loop() if (gps.available()) char c = gps.read(); Serial.print(c); // Echo GPS data to Serial Monitor

void loop() if (port1.available()) // Process port1 data
