ArduPilot RemoteID Transmitter

This is an implementation of a MAVLink and DroneCAN OpenDroneID transmitter. It aims to provide a transmitter solution for the FAA standard RemoteID requrement, meeting the transmitter component of the ASTM F3586-22 Means of Compliance.

Hardware Supported

So far the only hardware that has been tested is the ESP32-S3. This devboard is being used: https://au.mouser.com/ProductDetail/356-ESP32S3DEVKTM1N8

Hardware from https://wurzbachelectronics.com/ and https://bluemark.io/ is expected to work and will be tested soon.

The pins assumed in this firmware are:

UART TX on pin 17
UART RX on pin 18
CAN TX on pin 47
CAN RX on pin 38

For CAN a suitable 1MBit bxCAN transceiver needs to be connected to the CAN TX/RX pins.

You can also do MAVLink on the USB UART port (the one marked "UART" on the silkscreen). That allows for easy simulation testing by plugging in a micro USB cable.

Transmission Modes

This firmware supports the following transmission modes:

WiFi NAN (Neighbour Awareness Networking)
Bluetooth 4 Legacy Advertising
Bluetooth 5 Long Range + Extended Advertising

Protocols

This firmware supports communication with an ArduPilot flight controller either using MAVLink or DroneCAN.

For MAVLink the following service is used: https://mavlink.io/en/services/opendroneid.html

For DroneCAN the following messages are used: https://github.com/dronecan/DSDL/tree/master/dronecan/remoteid

The DroneCAN messages are an exact mirror of the MAVLink messages to make a dual-transport implementation easy.

Releases

Pre-built releases are in the releases folder on github

Flashing

To flash to an ESP32-S3 board use the espressif FlashTool from https://www.espressif.com/en/support/download/other-tools

if this is the first time flashing the board, you may need to hold the "boot" button down while attaching the USB cable to the USB connector marked "USB"

and then use the pre-built binary in the releases folder to flash using the following options, after selecting the COMM port that the board is attached:

subsequent re-flashing of newer releases should not require holding the "boot" button during power-up of the board as the USB cable is attached.

ArduPilot Support

Support for OpenDroneID is in ArduPilot master and is pending for addition to the 4.2.x stable releases. You need to enable it on a board by setting "define AP_OPENDRONEID_ENABLED 1" in the hwdef.dat for your board.
