I. Principles

When using ArduPilot firmware, the flight controller supports wireless data transmission and tuning with QGroundControl or MissionPlanner via Bluetooth SPP (Serial Port Profile) mode.

  • Bluetooth SPP Mode: The Bluetooth Serial Port Profile (SPP) converts wireless data into virtual serial port communication, allowing mobile devices to interact with the flight controller as if connected via a data cable.
  • Firmware Data Exchange: Various sensor data and control commands from the flight controller board are transmitted via serial port. The ground control station software establishes a virtual serial port connection through Bluetooth to receive real-time flight data and send parameter configuration commands.
  • Wireless Connection Advantages: Using Bluetooth SPP mode eliminates the hassle of cable connections, improving operational convenience. It is particularly suitable for quickly adjusting flight controller parameters and monitoring flight status in the field.

II. Device Preparation

To establish a Bluetooth SPP mode connection, ensure you have the following devices and materials:
1. Flight Controller Equipment
1) SpeedyBee F405 WING APP flight controller - flashed with ArduPilot firmware
