Notes on differences between M100 and A3/N3/M600/M210 setup

Onboard SDK ROS is backward compatible with M100. However, due to the limitations of the flight controller of M100, some new features such as hardware sync, MFIO, on demand telemetry data (subscription) are only supported by A3/N3, and some settings for M100 are different from those for A3/N3.

  1. The DJI Assistant 2 for M100 and for A3/N3 are slighly different. Please download DJI Assistant 2 from the corresponding product webpage.

  2. The DJI SDK ROS package requires different baud rate for M100 and A3/N3. For M100, set the baud rate to 230400 in DJI Assistant 2's "SDK" tab, and the sdk.launch file; while for A3/N3/M600/M210, use 921600.

  3. For M100, on the right side of the "SDK setting" tab of DJI Assistant 2, set the Data Type of ACC and GYRO to "Raw Data", and ALTI to "Data Fusion". The reason is that the raw data of acc and gyro are part of the /dji_sdk/imu message.

  4. The flight_status enums for M100 and A3/N3 are different. See dji_sdk.h for details and demo_flight_control for examples.

  5. Some topics are only available on A3/N3: display_mode, angular_velocity_fused, acceleration_ground_fused, trigger_time.

  6. The imu topic is published at 400Hz on A3/N3, and at 100Hz on M100.

  7. Some services are only available on A3/N3: mfio_config, mfio_set_value, set_hardsyc
