 ## Test your changes

-PX4 is safety-critical software. All contributions must include adequate testing where practical:
-
- **New features** must include unit tests and/or integration tests that exercise the new functionality, where practical. Hardware-dependent changes that cannot be tested in SITL should include bench test or flight test evidence.
- **Bug fixes** must include a regression test where practical. When automated testing is not feasible (hardware-specific issues, race conditions, etc.), provide a link to a flight log demonstrating the fix and the reproduction steps for the original bug.
- **Reviewers** will verify that tests or test evidence exist before approving a pull request.
-
-### Types of tests
-
-| Test type | When to use | How to run |
-|-----------|-------------|------------|
-| **Unit tests** (gtest) | Module-level logic, math, parsing | `make tests` |
-| **SITL integration tests** (MAVSDK) | Flight behavior, failsafes, missions | `test/mavsdk_tests/` |
-| **Bench tests / flight logs** | Hardware-dependent changes | Upload logs to [Flight Review](https://logs.px4.io) |
-
 Since we care about safety, we will regularly ask you for test results. Best is to do a test flight (or bench test where it applies) and upload the log file from it (on the microSD card in the logs directory) to Google Drive or Dropbox and share the link.

-3. **Disclosure**: We coordinate disclosure with the reporter. We follow responsible disclosure practices and will credit reporters in the advisory unless they request anonymity.
-
-If you do not receive acknowledgment within 7 days, please follow up by emailing the [release managers](MAINTAINERS.md).
-
-## Secure Development Practices
-
-The PX4 development team applies the following practices to reduce security risk:
-
- **Code review**: All changes require peer review before merging.
- **Static analysis**: [clang-tidy](https://clang.llvm.org/extra/clang-tidy/) runs on every pull request with warnings treated as errors.
- **Fuzzing**: A daily fuzzing pipeline using [Google fuzztest](https://github.com/google/fuzztest) tests MAVLink message handling and GNSS driver protocol parsing.
- **Input validation**: All external inputs (MAVLink messages, RC signals, sensor data) are validated against expected ranges before use.
- **Compiler hardening**: Builds use `-Wall -Werror`, stack protectors, and other hardening flags where supported by the target platform.
+At the bottom of the form, click Submit report. The maintainer team will be notified and will get back to you ASAP.

-Most fixed-wing aircraft cannot generate a sustained yaw rate using the rudder alone. As a result, the yaw component of the quaternion attitude error should be removed before computing the control action.

-
-<Badge type="tip" text="PX4 v1.17" />
-
-MAVLink is an open communication protocol designed for lightweight, low-latency communication between drones and ground stations.
-By default, all MAVLink messages are unauthenticated.
-This is intentional for development and testing, but **production deployments must enable [message signing](message_signing.md)** to prevent unauthorized access.
-
-::: warning
-Without message signing enabled, any device that can send MAVLink messages to the vehicle (via radio, network, or serial) can execute any command, including shell access, file operations, parameter changes, mission uploads, arming, and flight termination.
-:::
-
-## What Is at Risk
-
-When MAVLink signing is not enabled, an attacker within communication range can:
-
-| Capability                   | MAVLink mechanism                                |
-| ---------------------------- | ------------------------------------------------ |
-| Execute shell commands       | `SERIAL_CONTROL` with `SERIAL_CONTROL_DEV_SHELL` |
-| Read, write, or delete files | MAVLink FTP protocol                             |
-| Change any flight parameter  | `PARAM_SET` / `PARAM_EXT_SET`                    |
-| Upload or overwrite missions | Mission protocol                                 |
-| Arm or disarm motors         | `MAV_CMD_COMPONENT_ARM_DISARM`                   |
-| Terminate flight (crash)     | `MAV_CMD_DO_FLIGHTTERMINATION`                   |

-| Reboot the vehicle           | `MAV_CMD_PREFLIGHT_REBOOT_SHUTDOWN`              |
-
-All of these are standard MAVLink capabilities used by ground control stations.
-Without signing, there is no distinction between a legitimate GCS and an unauthorized sender.
-
-## Hardening Checklist
-
-### 1. Enable Message Signing
-
-Message signing provides cryptographic authentication for all MAVLink communication.
-See [Message Signing](message_signing.md) for full details.
-
-Steps:
-
-1. Connect the vehicle via **USB** (key provisioning only works over USB).
-2. Provision a 32-byte secret key using the [SETUP_SIGNING](https://mavlink.io/en/messages/common.html#SETUP_SIGNING) message.
-3. Set [MAV_SIGN_CFG](../advanced_config/parameter_reference.md#MAV_SIGN_CFG) to **1** (signing enabled on all links except USB) or **2** (signing on all links including USB).
-4. Provision the same key on all ground control stations and companion computers that need to communicate with the vehicle.
-5. Verify that unsigned messages from unknown sources are rejected.
-
-::: info
-`MAV_SIGN_CFG=1` is recommended for most deployments.
-This enforces signing on telemetry radios and network links while allowing unsigned access over USB for maintenance.
-USB connections require physical access to the vehicle, which provides equivalent security to physical key access.
-:::
-
-### 2. Secure Physical Access
-
- Protect access to the SD card. The signing key is stored at `/mavlink/mavlink-signing-key.bin` and can be read or removed by anyone with physical access.
- USB connections bypass signing when `MAV_SIGN_CFG=1`. Ensure USB ports are not exposed in deployed configurations.
-
-### 3. Secure Network Links
-
- Do not expose MAVLink UDP/TCP ports to untrusted networks or the internet.
- Place MAVLink communication links behind firewalls or VPNs.
- Segment MAVLink networks from business or public networks.
- When using companion computers, audit which network interfaces MAVLink is bound to.
-
-### 4. Understand the Limitations
-
- **No encryption**: Message signing provides authentication and integrity, but messages are sent in plaintext. An eavesdropper can read telemetry and commands but cannot forge them.
- **Allowlisted messages**: A small set of [safety-critical messages](message_signing.md#unsigned-message-allowlist) (RADIO_STATUS, ADSB_VEHICLE, COLLISION) are always accepted unsigned.
- **Key management**: There is no automatic key rotation. Keys must be reprovisioned manually via USB if compromised.
-
-## Integrator Responsibility
-
-PX4 is open-source flight controller firmware used by manufacturers and system integrators to build commercial and custom drone platforms.
-
-Securing the communication links for a specific deployment is the responsibility of the system integrator.
-This includes:
-
- Choosing appropriate radio hardware and link security
- Enabling and managing MAVLink message signing
- Restricting network access to MAVLink interfaces
- Applying firmware updates that address security issues
- Evaluating whether the default configuration meets the security requirements of the target application
-
-PX4 provides the tools for securing MAVLink communication.
-Integrators must enable and configure them for their deployment context.

 ### Description

-This is the DShot output driver. It can be used as drop-in replacement
+This is the DShot output driver. It is similar to the fmu driver, and can be used as drop-in replacement
 to use DShot as ESC communication protocol instead of PWM.

+On startup, the module tries to occupy all available pins for DShot output.
+It skips all pins already in use (e.g. by a camera trigger module).
+
 It supports:

 - DShot150, DShot300, DShot600
 - telemetry via separate UART and publishing as esc_status message
+- sending DShot commands via CLI
+
+### Examples
+
+Permanently reverse motor 1:
+
+```
+dshot reverse -m 1
+dshot save -m 1
+```
+
+After saving, the reversed direction will be regarded as the normal one. So to reverse again repeat the same commands.

 ## Bidirectional DShot (Telemetry)

 <Badge type="tip" text="PX4 v1.16" />

-Bidirectional DShot (BDShot) enables the ESC to send eRPM telemetry back to the flight controller on the same signal wire used for throttle commands — no additional telemetry wire is needed for RPM data.
-High-rate eRPM data significantly improves the performance of [Dynamic Notch Filters](../config_mc/filter_tuning.md#dynamic-notch-filters) and enables more precise vehicle tuning.
+Bidirectional DShot is a protocol that can provide telemetry including: high rate ESC RPM data, voltage, current, and temperature with a single wire.

-With [Extended DShot Telemetry (EDT)](#extended-dshot-telemetry-edt) enabled, BDShot can also provide temperature, voltage, and current data.
-
-### Hardware Support
-
-BDShot requires a flight controller with DMA-capable timers.
-Any FMU output on a supported timer can be used for BDShot — multiple timers are supported through sequential burst/capture.
-
-Supported processors:
-
- **STM32H7**: All FMU outputs on DMA-capable timers
- **i.MXRT** (V6X-RT & Tropic): All FMU outputs
+The PX4 implementation currently enables only ESC RPM (eRPM) data collection from each ESC at high frequencies.
+This telemetry significantly improves the performance of [Dynamic Notch Filters](../config_mc/filter_tuning.md#dynamic-notch-filters) and enables more precise vehicle tuning.

 ::: info
-The ESC must be connected to FMU outputs only.
-These are labeled `MAIN` on controllers with a single PWM bus, and `AUX` on controllers with both `MAIN` and `AUX` ports (i.e. those with an IO board).
+The [ESC Telemetry](#esc-telemetry) described above is currently still necessary if you want voltage, current, or temperature information.
+It's setup and use is independent of bidirectional DShot.
 :::

-### PX4 Configuration {#bidirectional-dshot-configuration}
+### Hardware Setup

-BDShot is enabled **per-timer** in the [Actuator Configuration](../config/actuators.md) UI.
-Select **BDShot150**, **BDShot300**, or **BDShot600** as the output protocol instead of the corresponding DShot speed.
-There is no separate enable parameter — choosing a BDShot protocol activates bidirectional telemetry on that timer's outputs.
+The ESC must be connected to FMU outputs only.
+These will be labeled `MAIN` on flight controllers that only have one PWM bus, and `AUX` on controllers that have both `MAIN` and `AUX` ports (i.e. FCs that have an IO board).

-The system calculates actual motor RPM from eRPM data using per-motor pole count parameters: `DSHOT_MOT_POL1` through `DSHOT_MOT_POL12` (one per motor output).
-The default is 14 poles, which is typical for 5-inch prop motors.
-If you are using AM32 ESCs, the motor pole count must also be set in the AM32 firmware configuration (e.g. via the AM32 configurator tool) to match.
+::: warning **Limited hardware support**
+This feature is only supported on flight controllers with the following processors:

-### Extended DShot Telemetry (EDT)
+- STM32H7: First four FMU outputs
+  - Must be connected to the first 4 FMU outputs, and these outputs must also be mapped to the same timer.
+  - [KakuteH7](../flight_controller/kakuteh7v2.md) is not supported because the outputs are not mapped to the same timer.
+- [i.MXRT](../flight_controller/nxp_mr_vmu_rt1176.md) (V6X-RT & Tropic): 8 FMU outputs.

-EDT extends BDShot by interleaving temperature, voltage, and current data into the eRPM telemetry frames.
-This allows ESC health monitoring through the same signal wire, without requiring a separate serial telemetry connection.
+No other boards are supported.
+:::

-To enable EDT:
+### Configuration {#bidirectional-dshot-configuration}

-1. Configure BDShot on the desired outputs (see above).
-2. Set `DSHOT_BIDIR_EDT` to `1` and reboot.
+To enable bidirectional DShot, set the [DSHOT_BIDIR_EN](../advanced_config/parameter_reference.md#DSHOT_BIDIR_EN) parameter.

-The ESC firmware must support EDT (e.g. [AM32](https://github.com/am32-firmware/AM32)).
-
-When both serial telemetry and BDShot/EDT are enabled, the driver merges data from both sources.
-
-## AM32 ESC Settings (EEPROM)
-
-PX4 can read and write AM32 ESC firmware settings (EEPROM) via a ground station, enabling remote ESC configuration without connecting directly to each ESC.
-
-### Requirements
-
- ESCs running [AM32 firmware](https://github.com/am32-firmware/AM32) with serial telemetry connected ([DSHOT_TEL_CFG](../advanced_config/parameter_reference.md#DSHOT_TEL_CFG))
- `DSHOT_ESC_TYPE` set to `1` (AM32)
- Ground station with ESC EEPROM support (QGroundControl feature in development)
- MAVLink development dialect enabled on the flight controller
-
-### How It Works
-
-PX4 automatically reads the full EEPROM from each ESC on boot.
-The ground station can then display individual settings and allow the user to modify them.
-Changes are written back to the ESC one byte at a time using the DShot programming protocol.
+The system calculates actual motor RPM from the received eRPM data using the [MOT_POLE_COUNT](../advanced_config/parameter_reference.md#MOT_POLE_COUNT) parameter.
+This parameter must be set correctly for accurate RPM reporting.
