New Fields Added

  1. trajectory_id (string) - For naming/identifying trajectories
  2. initial_position (GNSSPosition) - Starting position of trajectory
  3. test_points (repeated GNSSPosition) - Test points for positioning algorithms
  4. sensor_info - Information for 7 sensors:
    • accelerometer_info
    • gyroscope_info
    • rotation_vector_info
    • magnetometer_info
    • barometer_info
    • light_sensor_info
    • proximity_info
  5. WiFiAPData.rtt_enabled (bool) - RTT support flag
  6. BleData enhanced with:
    • mac_address, name, tx_power_level
    • advertise_flags, service_uuids, manufacturer_data

Breaking Changes - API Updates

Structure Changes

IMU Data - Now uses Vector3/Quaternion:

// OLD
.setAccX(x).setAccY(y).setAccZ(z)

// NEW
.setAcc(Traj.Vector3.newBuilder().setX(x).setY(y).setZ(z).build())

GNSS Data - Position nested in GNSSPosition:

// OLD
.setLatitude(lat).setLongitude(lon).setAltitude(alt)

// NEW
.setPosition(Traj.GNSSPosition.newBuilder()
    .setLatitude(lat).setLongitude(lon).setAltitude(alt).build())

Files Modified

  • Traj.java - Regenerated from proto
  • SensorFusion.java - Updated API calls
  • ServerCommunications.java - Updated API calls
  • app/build.gradle - Updated protobuf dependency to 4.29.6
