How to use GPS module with SIM800L Module?

[poydevelop]

I can't find the document. help me please.

Change the pins for the GPS module as follows (by cutting the existing bridge and re-soldering). Only downside is, that the Serial monitor/output is not available anymore

• RXD: 1
• TXD: 3
• PPS (not connected)

Now, you can use the GPS module on the serial port 0:

// The TinyGPS++ object
TinyGPSPlus gps;
// The serial connection to the GPS device
HardwareSerial gps_serial(0);
gps_serial(GPSBaud);

// ... (within a loop/smart delay)
while (gps_serial.available())
    gps.encode(gps_serial.read());

For the SIM800L you can use the regular configuration without changing anything:

...
#define SerialAT Serial2
TinyGsm modem(SerialAT);
TinyGsmClient client(modem);
...
