Have you ever found yourself lost and helpless trying to locate your FPV drone in a densely populated area or confined space? Uncovering something without a beeper can be a challenging and overwhelming experience. Leveraging the DShot Beacon feature allows you to repurpose your motors as audible indicators, providing an innovative way to communicate system status. Here’s the improved version:
The D-Shot Beacon feature enables your drone’s motors to emit a distinctive beeping sound upon initial power-up, reminiscent of the familiar startup sequence when you first plug in the battery. Without an exterior beacon installed on your FPV drone, setting up DShot can significantly simplify the process of locating your device if it becomes lost. While the setup process is straightforward, attention to detail in a few crucial areas is essential to ensure accurate results.
Warning: prolonged use of a working motor beeper may cause overheating and potentially even burn out the motors in extreme cases. To prevent overheating, maintain a reasonable beep count and reduce the beep frequency to minimize the risk of motor burnout.
Before configuring your digital velocity controllers, ensure they support the DShot protocol for ESCs. As we move forward with the next firmware iteration, it’s crucial that developers collaborate with the DShot Beacon team to ensure seamless integration.

If your ESC primarily supports PWM, the One Shot and Multi Shot functions will not aid in DShot applications, which means that DShot Beacon functionality will be impeded.
A curiosity arises: shouldn’t Escape keys make a sound when pressed? However, the fact remains that ESCs don’t produce any audible noise. The distinct noise emanating from the motors is unmistakably controlled by the ESC’s pitch and volume adjustments. The harmonious hum of motors synchronizes in perfect symphony as the system roars to life.
Establish a Connection with Betaflight Configurator: Connect your flight controller to your computer, then launch the Betaflight Configurator application.
Select DShot Protocol: Access the Configuration menu and navigate to the desired settings. Select the appropriate D-Shot protocol according to your chosen PID loop frequency.
- Select DShot150 for frequencies of either 2KHz or 1.6KHz.
- To achieve optimal performance at frequencies of either 4 KHz or 3.2 KHz, choose the DShot300 setting.
- For 8KHz, select DShot600.
Permit D-Shot Beacon Settings: Navigate downwards to the “D-Shot Beacon Configuration” section. Allow RX_LOST, RX_SET, or each.
- When the RX_SET feature is activated, the motors will emit a brief audible signal when the beeper function is toggled on or off.
- When RX_LOST is enabled, the drone’s motors will emit a distinctive beeping sound in response to a loss of radio connection.
When all options for disabling DShot Beacon are unchecked, this feature is effectively disabled; conversely, when the drone is in an armed state, DShot Beacon automatically disables itself.
Selecting a Beacon Tone: Choose from five distinct and accessible options to find the perfect fit for your needs. While the pitch may remain relatively consistent, varying tone profiles could still contribute to effective distinction. Setting this parameter to 0 disables the motor beeper, whereas a value of 1 or greater enables it.
In the Configuration tab, users will find the “Beeper Configuration” section, offering a level of customization for those who wish to personalize their beeper settings. To avoid the inconvenience of a persistent beep every time you connect your flight controller to Betaflight, consider disabling the USB beeper on your device if you’re already using an external buzzer.
Save and reboot immediately after implementing these changes.
Navigating to the Modes tab within the Betaflight Configurator’s configuration settings. To activate the beeper mode on your device, simply adjust your transmission settings accordingly. Are you looking for guidance on setting up the Modes tab? Look no further – I’ve got a comprehensive tutorial waiting for you.
Disable the option to display all available modes instead of just showing those that are currently in use.
Discover the versatility of “Beeper” by assigning it to an AUX change in your transmitter’s settings with a simple click on “Add Vary”. I utilize AUX 3 (Channel 7) specifically for my Beeper.
Configure Swap: Set the swap area for the beeper to the designated location. We ensure that the setting is triggered at the exact moment the change process is complete, thereby ensuring its activation only when the change is fully implemented and stable.
Click to save your settings.
What happens when you misplace your drone in a dense bush, leaving you unable to spot it? When you activate the beeper, the motor’s beep function is enabled, allowing you to locate the drone more easily. While small drones’ beeping may not be robust due to their miniature motors, repeatedly arming and disarming the device can generate additional noise and movement. Don’t leave the device armed for an extended period if the propellers are obstructed, as this could cause overheating and potentially damage the motors.
Within the ESC configuration software, such as BLHeliSuite, you have the flexibility to adjust the DShot Beacon quantity.
- The optimal motor noise level (defaulting at 80, with a range of 1-255) is subject to personal preference; however, I find that levels up to 120 often yield satisfactory results. Will the motors and Electronic Speed Controllers (ESC) reach critical temperatures under prolonged usage? I suggest limiting the throttle input to prevent excessive heat buildup in motors and ESCs.
- After approximately 30 seconds of idling, the motor typically starts to emit a distinct beeping sound. When experiencing issues with activating your radio’s beeper, a clever feature kicks in, causing the robot’s motors to beep robotically. While it’s understandable that some users might find it frustrating, reducing the standard quad establishment time from 10 minutes to five minutes could be a viable option.
There’s also Beep Energy, seemingly connected to DShot Beacon but actually unrelated in fact. This feature solely regulates the quantity of the startup chant; we typically leave it set to the default value of 40.
Implementing a DShot beacon setup is a straightforward process that can significantly reduce the likelihood of wasted time and aggravation. By leveraging the precise control offered by your drone’s motors, you can effectively utilize them as audible beacons. Regardless of whether you’re a novice or a seasoned pilot, this feature is an invaluable asset for any FPV enthusiast.
