Enable CAN port, DroneCAN, and Configure for NEO-V2 Pro

See CAN Bus Setup and DroneCAN Setup for more information.

Set the following parameters in all parameter tables of Mission planner and restart after writing

NEO-V2 is now ready for operation

SLCAN Interface

If you need to set up NEO V2 PRO or upgrade its firmware, you need to enable SLCAN

Note

ArduPilot 4.0 or later firmware supports SLCAN.

  • Please connect NEO V2 pro to the autopilot’s CAN1 interface.

  • Open mission planner and connect autopilot.

Modify the following parameters in the Full Parameter tab of Mission Planner.

for CUAV V5+/nano:

Note

CUAVV5 / NANO / FMUV5 autopilot running ArduPilot4.0 or later firmware will have two USB interfaces, one is autopilot’s console port (SERIAL0) running MAVLINK and one is an SLCAN interface port; if there are not two ports showing in the Mission Planner Comm Port drop-down box, please uninstall the driver and reinstall. If you continue to have problems, see Troubleshooting Composite Connections

For Pixhawk series / FMUv2 / FMU V3 / FMU V4

Note

STM32F4 does not support dual virtual USB ports, so autopilots using STM32F4 processor can only be used for SLCAN after the MAVLink connection on USB is closed; after writing the above settings, the USB interface becomes an SCLAN port; MAVLink connections can be made again after a reboot. Until then the USB connection can be used for SLCAN operations.

NEO-V2 Internal Configuration

ArduPilot supports setting DroneCAN device internal settings through SLCAN, such as modifying node ID; enabling / disabling barometer, etc.
