MAVBridge is stand-alone ESP8266 based serial MAVLink <-> wireless bridge. It is compatible with MAVLink v1.0 specification and
Compatibility has been tested with:
- Pixhawk hardware (PX4 and ArduPilot flight stacks)
Device has built-in web interface for configuration and status.
At the moment, only UDP transport layer is supported. TCP support is work-in-progress (functionality is there, but ESP runs out of RAM and crashes when transmitting a lot of data).
As for performance- UDP has been successfully tested at 921600 baud rate and almost 70 KiB/s data rate without packet-loss (depends on number of WiFi networks around device , of course).
Prerequisites for building:
- https://github.com/pfalcon/esp-open-sdk with Espressif IOT SDK 1.5.2
- Sming framework: https://github.com/SmingHub/Sming/releases/tag/2.1.0
Assuming the requirements above are satisfied, building is as simple as:
cd firmware make
Hardware is designed using Kicad and the design is available in hardware folder.
Python scripts that automatically test performance and stability of the
MAVBridge are available in
throughput-test/. Tests require pymavlink.
