GPS

Switch GPS on Reports NMEA strings A parsing example in SDK

• Fix• # Satellites• Date stamp• Position

void setup() {Serial.begin(115200);LGPS.powerOn();

}

void loop() {LGPS.getData(&info);Serial.println(info.GPGGA); parseGPGGA(info.GPGGA);

}

GPRS

Attach GPRSto network

Use LGPRS Clientto create HTTP GETrequest

Read response

LGPRSClient client;void setup(){while (!LGPRS.attachGPRS())

delay(500);

if (client.connect(server, port)){client.print("GET ");client.print(path);… }

}void loop(){if (client.available()){char c = client.read();Serial.print(c);
