Magnetometer reading

[Electricaz]

Thank you for the great code, very helpful.
I’ve been trying to read magnetometer from MPU9255 but no luck, readings are 0 and would appreciate your support.
Gyroscope and Accelerometer working fine.
here is the

MPU.acceleration(&accelRaw);  // fetch raw data from the 
MPU.rotation(&gyroRaw);       // fetch raw data from the 
MPU.heading(&compassRaw);
MPU.motion(&accelRaw, &gyroRaw, &compassRaw);
float mx = compassRaw[0] * 1.499;
float my = compassRaw[1] * 1.499;
float mz = compassRaw[2] * 1.499;
printf("mx = %f \t my = %f \t mz = %f\n",mx,my,mz);
