Re: ublox max 7

The uBlox Max technical reference datasheet shows the response. I will look it up when i get off work. -Bill WB8ELK

What should I expect as a response from the checkNav command. Is there a document that describes this command.

You have to set the MAX-7Q up for Airborne mode to make it work and it will fail at 40,000 feet if you don't. - Bill WB8ELK

 

Here is how I do it:

 

============================================

unsigned char setNav[] = {

    0xB5, 0x62, 0x06, 0x24, 0x24, 0x00, 0xFF, 0xFF, 0x06, 0x03, 0x00, 0x00, 0x00, 0x00, 0x10, 0x27, 0x00, 0x00, 0x05, 0x00, 0xFA, 0x00, 0xFA, 0x00, 0x64, 0x00, 0x2C, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x16, 0xDC  };

 

//  Set uBlox MAX series to Airborne Mode

 

   for(int i=0; i<44; i++){ // 

     Serial.write(setNav[i]);

   }

============================================

 

// The whole GPS_setup routine:(put the setNav array shown above in Global variable section or in the function)

 

// ****************************************/

void setupGPS() 

// *****************************************

{

  // setup serial port for u-Blox MAX-7C GPS new 110115

    Serial.begin(9600); // to talk to GPS Modem via RX and TX pins 0 and 1

       delay(10);

    Serial.flush();

       delay(10); 

 

// Configure uBlox MAX to only output GGA and RMC messages  

  Serial.println("$PUBX,40,GLL,0,0,0,0*5C");

  delay(1000);

//  Serial.println("$PUBX,40,GGA,0,0,0,0*5A");

//  delay(1000);

  Serial.println("$PUBX,40,GSA,0,0,0,0*4E");

  delay(1000);

//  Serial.println("$PUBX,40,RMC,0,0,0,0*47");

//  delay(1000);

  Serial.println("$PUBX,40,GSV,0,0,0,0*59");

  delay(1000);

  Serial.println("$PUBX,40,VTG,0,0,0,0*5E");

  delay(3000);

 

// Set up uBlox MAX series to Airborne Mode

   for(int i=0; i<44; i++){ // 

     Serial.write(setNav[i]);

   }

   

   delay(500);

   

   Serial.end(); // new 110115

     

   return;

}

// ---------------end of setupGPS()----------------------/

 

You can check to see if you have successfully configured the uBlox MAX to be set for Airborne mode by looking at the response to this command:

 

unsigned char checkNav[] = {0xB5, 0x62, 0x06, 0x24, 0x00, 0x00, 0x2A, 0x84};

 

    for(int i=0; i<sizeof(checkNav); i++){ 

      Serial.write(checkNav[i]);

    }
