Hey @rmackay9 , want to report a bug in speedybee f405, i was intergrating tfluna and in the parameters list got to know that prx parameters not present in this.
Hi @Dtown,
It depends upon which version of AP is being used but for the F405 based autopilot’s they don’t have enough flash space to fit all features. It’s best to upgrade to an H7 or maybe the custom build server can be used. ArduPilot Custom Firmware Builder — Copter documentation
i have used 4.5.7 firmware version
So go to the Custom Firmware Builder and try to add Proximity to a build. You may have to remove some other things for success.
