Evaluating Gazell Protocol and nRF52840DK Board for Agri UGV Control - Need Suggestions

Hello Nordic Devzone Community,

I am currently designing a remote control system for an Agricultural Unmanned Ground Vehicle (UGV), and have some specific technical inquiries that I hope to get your insights on.

Our system has several high-level requirements:

  1. Easy pairing between the transmitter and receiver: The system needs to facilitate easy and secure pairing.

  2. Bi-directional, low-latency communication: The transmitter will send joystick values (under 10Hz) and button data to the UGV, while the UGV sends back vehicle parameter data for display. The communication needs to be prompt with minimal latency. My data transfer is not high at few CANbus frames/seconds

  3. CAN Bus Interface: The receiver on the UGV will interface with a CAN Bus to send the received data to the various systems within the vehicle.

  4. Robustness and Range: The system must be robust and have a reliable communication range of less than 100 meters LOS.

  5. Multiple Vehicles: The system should handle 4-5 vehicles simultaneously in the same vicinity without interference.

  6. Security: The whole system is closed and should not give access to an external party.

Currently, I am considering using the Gazelle protocol for its low latency capabilities and trying out the nRF52840DK board. In this context, I have a couple of follow-up queries:

  1. Are the Gazelle protocol and the nRF52840DK board good fits for these requirements? If not, do you have any alternative suggestions?

  2. Can we use NFC to trigger pairing in the Gazelle protocol? If yes, are there any particular considerations for this setup?

I would appreciate any advice, experiences, or caveats you might share to help guide our decision-making process.

Thank you in advance!

Best Regards,
