Setup & Configuration

The RemoteID Module is controlled by the autopilot system. For normal operation, make sure the module is powered on (LED is on) and make sure the module can communicate with the autopilot system. The Holybro RemoteID module can be configured via the CAN bus (DroneCAN) or UART/TELEM (MAVLink). For instance, you can configure the transmission modes, set the UAS_ID etc.

PX4

PX4 has support for Remote ID in version PX4 v1.14 and newer. See this link for the latest information: https://docs.px4.io/main/en/peripherals/remote_id.html

Ardupilot

Note: For ArduPilot, the standard firmware does not include Remote ID functionality. You need to compile your own ArduPilot with Remote ID included. See this page for more information: https://ardupilot.org/dev/docs/opendroneid.html

A video guide on How to add RemoteID to ArduPilot Systems: https://www.youtube.com/watch?v=Az8v4Kx4hS0

Currently, the MAVLink interface only supports editing integer parameters. Therefore, we recommend to connect the module via DroneCAN.

Connecting to Flight Controller

With DroneCAN

In this section, the RemoteID is connected to the flight controller using the DroneCAN/CAN interface. Open MissionPlanner and make sure you run the latest stable version (1.3.77 or higher).

Set the following parameters in MissionPlanner (Config --> Full Parameter List):

• DID_ENABLE 1

• DID_OPTIONS 1

• DID_MAVPORT -1

• DID_CANDRIVER 1

• AHRS_EKF_TYPE 3

• GPS_TYPE 1

• GPS_TYPE2 0

In MissionPlanner go to Setup --> Optional Hardware --> DroneCAN/UAVCAN. Click on the top button called “MAVLink CAN1”.

If the module is connected to CAN2, the click on the button called “MAVLink CAN2”. After a few seconds, the list of connected CAN devices should be listed. The RemoteID Module should be one of the devices. Click on the menu action-button on the right of the module name and select parameters. Then the list of parameters will be displayed

With Mavlink (serial)

In this section, the RemoteID is connected to the flight controller using the MAVLink/TELEM interface. Open MissionPlanner and make sure you run the latest stable version (1.3.77 or higher).

Set the following parameters in MissionPlanner (Config --> Full Parameter List):

• DID_ENABLE 1

• DID_OPTIONS 1

• DID_MAVPORT X (where x is the serial port attached to OpenDroneID module)

• DID_CANDRIVER 0

• AHRS_EKF_TYPE 3

• GPS_TYPE 1

• GPS_TYPE2 0

• SERIALX_BAUD 57 (where X is the serial port attached to OpenDroneID module. Set this to 57, 57600 baud rate)

• SERIALX_PROTOCOL 2 (where X is the serial port attached to OpenDroneID module. Set this to 2, MAVLink2 mode.)

Below the COM port settings, select the interface ending with -ODID TXRX 1. In MissionPlanner go

to Config --> Full Parameter List to see the list of Remote ID parameters. If the list is empty, press the Refresh Params button.
