GPS + RF433 Not working together.

rafitc99

I need to get GPS location while a Trigger occurs. I'm sending trigger via 433Mhz RF transmitter. In the receiver, part contains a GPS module (NEO-7M) to get GPS location and RF 433Mhz to receiver RF message. (Refer code) My problem is by combining GPS + RF. GPS module not giving location details. While checking i found that while (gps.available( gps_port )) not running while #include <VirtualWire.h> is occur. I got a similar error while using SoftwareSerial.h with Radiohead.h

What is the problem with these two libraries? Why Serial.available() not working in this code

#include <NMEAGPS.h>
#include <NeoSWSerial.h>
#include <VirtualWire.h> 

byte message[VW_MAX_MESSAGE_LEN]; // a buffer to store the incoming messages
byte messageLength = VW_MAX_MESSAGE_LEN; // the size of the message
int received_number = 0;
int LED = 5;
int i =0;


NeoSWSerial gps_port(6,7);
NMEAGPS gps;


void setup(){
  Serial.begin(9600);
  Serial.println( F("GPS Start") );  // F macro saves RAM

  gps_port.begin(9600);
  vw_set_rx_pin(11); // pin
  vw_setup(2000); // bps
  vw_rx_start();
}

void loop(){
    // Set buffer to size of expected message
    uint8_t buf[1];
    uint8_t buflen = sizeof(buf);
    // Check if received packet is correct size
  if (vw_get_message(message, &messageLength)) // non-blocking
  {
    Serial.print("Potentiometer: ");
      //Serial.print(message[i]);
      received_number = message[i];
    Serial.println(received_number);

      if(received_number == 1){
        Serial.println("Triggered");
        getGpsData();    
      }
    }
}

void getGpsData() {
  Serial.println("im here");
  while (gps.available( gps_port )) {
    
    gps_fix fix = gps.read();
    if (fix.valid.location) {
      
      float outArray[2];
      outArray[0] = fix.latitude();  // Arrays start at 0, not 1.  Did you really mean [1] here?
      outArray[1] = fix.longitude();

      Serial.println( F("Latitude:") );
      Serial.println( outArray[0], 6 );
      Serial.println( F("Longitude:") );
      Serial.println( outArray[1], 6 );
      Serial.println("___________");
    }
    else {
      Serial.println("GPS Not availble");
    }
  }
}

I got a similar error while using

Can you share the error here, also share the library link that you are using.

rafitc99

@salmanfaris Not syntax error. its not reading GPS data. That's the problem.

salmanfaris

What output you are getting? Just some zeros?

rafitc99

@salmanfaris No any output. Arduino not wating for GPS data.Not runing this loop while (gps.available( gps_port ))

salmanfaris

does it return one/true when you are testing only with gps and gps.available( gps_port )?

rafitc99

@salmanfaris gps.available( gps_port ) Is not return a True case.

rafitc99

@salmanfaris for running while(gps.avaible()); MCU need to wait some time. but after adding VirtualWire library it's not waiting for Serial.available()

ps.available( gps_port ) Is not return a True case.

Then how is the while loop will work? It should return!

library it's not waiting for Serial.available()

did you try manual waiting? Instead of delay, you can use mills, so the background works will keep run.
