This fixes RSSI for the Control Zero F7 but I have noticed that while this works perfectly for SBUS receivers, for PPM receivers it does not decrease the RSSI visual value in QGC when removing the RC transmitter connection. When a PPM receiver is connected and the connection is lost the autopilot goes into RC Scan Mode (in the RC Update Module) to determine what is connected (even though something already is connected). The main issue with this is that PPM receivers don't go into RC Failsafe but I don't think it is an issue with this autopilot. It looks to be an issue with the RC Update Module and how it is handled at the module level for non I/O coprocessor autopilots. Tested with an X8R (SBUS) and a Dragonlink (PPM) as well as a Dragonlink set to SBUS as the output. SBUS worked as intended. See screenshots below.
PX4 Drone Autopilot
This repository holds the PX4 flight control solution for drones, with the main applications located in the src/modules directory. It also contains the PX4 Drone Middleware Platform, which provides drivers and middleware to run drones.

PX4 Users
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
PX4 Developers
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
