In the rapidly evolving landscape of Unmanned Aerial Systems (UAS), the transition from simple radio-controlled hobbyist toys to sophisticated, data-driven machines has introduced a complex layer of digital management. For the modern pilot, “blocking” is no longer a term reserved for smartphone contacts; it is a critical component of signal management, Remote ID security, and fleet privacy. Whether you are operating a high-end cinematic rig or a fleet of delivery drones, understanding how to manage blocked hardware IDs, filtered frequency channels, and restricted telemetry streams is essential.

This guide explores the intricate “blocked lists” within drone applications, specifically focusing on how to identify, view, and manage these digital identifiers to ensure seamless flight operations and robust data security.
The Role of Digital IDs and Block Lists in Modern Aviation
As airspace becomes more crowded, the need for identification and filtering has grown exponentially. In the context of drone accessories and applications, “numbers” typically refer to unique hardware identifiers, Remote ID serials, or specific RF (Radio Frequency) channels. Managing these is a core function of the Ground Control Station (GCS) software.
Remote ID and the Digital License Plate
Under the FAA’s Remote ID mandates and similar international regulations, drones act as digital broadcasters. Each drone transmits a unique “number”—its serial identifier—into the surrounding airspace. In professional settings, particularly when multiple pilots are operating in close proximity, your app may “block” or filter out the IDs of surrounding drones to reduce screen clutter and prevent telemetry confusion. Understanding how to see which IDs are currently being ignored by your system is the first step in troubleshooting connectivity issues in crowded environments.
Why Filters and Block Lists are Necessary for Pilots
Filtering is not just about organization; it is about safety. In high-interference zones, or when operating near sensitive infrastructure, a pilot may need to block specific frequency ranges or hardware handshakes that could compromise the drone’s command and control (C2) link. By “blocking” certain interference-heavy channels or unauthorized mobile device IDs from attempting to pair with the controller, the pilot maintains a “clean” operational environment.
Navigating the Settings: Finding Your Blocked List in Drone Apps
Most professional-grade drone apps, such as DJI Fly, Autel Explorer, and various Open Source Ground Control Stations (like QGroundControl), house their filter and block settings within the advanced security or transmission menus. Locating these “numbers” requires a deep dive into the software architecture.
Managing Blocked Remote ID Serials in DJI Fly and DJI Pilot 2
For DJI users, the “blocked” list often manifests as a filter within the “Identify” or “AirSense” menus. When a pilot encounters multiple Remote ID signals, the app allows the user to “Ignore” specific serial numbers. To see what you have blocked:
- Enter the Camera View and tap the three dots (…) in the top right corner.
- Navigate to the “Safety” tab.
- Scroll down to “Remote ID” or “AirSense” settings.
- Look for “Managed Device List” or “Ignored IDs.”
Here, you will see a list of the unique identification numbers of nearby aircraft that your system has been instructed to filter out of your primary HUD.
Autel and Parrot: Finding Hardware Filters
Autel and Parrot ecosystems utilize a more rigid “Authorized Device” protocol. If a controller or a secondary mobile device has been “blocked” from accessing the drone’s video downlink, these numbers (usually MAC addresses or encrypted hardware IDs) are stored in the “Security” or “Device Management” section. Accessing these lists is vital if you are attempting to hand over control to a secondary operator and find that their device is unable to “see” the aircraft.
Signal Management: Identifying Blocked Frequencies and Channels
In the world of drone accessories, the most important “numbers” are often the MHz and GHz frequencies used for transmission. Modern apps provide visual representations of the RF spectrum, where certain channels may be blocked out—either automatically by the software to avoid interference or manually by the pilot.

RF Environment Analysis
When you open the “Transmission” tab in your drone app, you are presented with a series of numbered channels (e.g., Channels 1 through 13 on 2.4GHz). If a channel appears grayed out or marked with an “X,” it has been effectively “blocked.” This can happen because:
- High Noise Floor: The app has detected too much ambient interference (from Wi-Fi routers or cell towers) and has blocked the drone from using that channel.
- Regional Restrictions: GPS-locked geofencing may block certain high-power channels depending on the country’s local telecommunications laws.
Manual Overrides in High-Interference Zones
To see which specific frequency numbers you have manually blocked or restricted, you must toggle the transmission mode from “Auto” to “Manual.” In manual mode, the “blocked” channels are highlighted. Professional pilots often block specific “numbers” (channels) to force the drone to stay on a stable, albeit narrower, frequency band, preventing the “frequency hopping” that can sometimes cause momentary lag or “jello” in the video feed.
Privacy and Security: Blocking Unauthorized Data Requests
With the rise of “Drone-to-Phone” broadcast technology, security-conscious pilots are increasingly interested in seeing which external entities are blocked from viewing their telemetry. This is a burgeoning area of drone app development, often found in the “Privacy” or “Data Management” settings.
Data Encryption and Telemetry Silencing
In enterprise applications, the drone’s “number” (its IP address within the local network) can be hidden or blocked from public discovery. To see the status of these blocks, pilots must check the “Local Data Mode” (LDM) settings. When LDM is active, all external “numbers”—meaning external server IP addresses—are blocked from receiving data from the drone.
Local Data Mode and Air-Gapping
For those working on sensitive government or infrastructure contracts, the “blocked list” is effectively the entire internet. In the app settings, seeing which “numbers” (IPs and Mac Addresses) are blocked confirms that the “Air-Gap” is functioning. This ensures that no flight logs, GPS coordinates, or imaging data are leaked to unauthorized third-party servers.
Advanced Troubleshooting: Unblocking Critical System IDs
Sometimes, a drone’s performance issues are caused by “blocked numbers” that shouldn’t be blocked. This usually occurs after a firmware update or a system crash where the “Ignore” list becomes corrupted.
When a Blocked Number Causes Flight Errors
If you are seeing a “Signal Weak” or “Disconnected” error despite being in close range, it is possible that the app has accidentally blacklisted the controller’s own internal communication ID. To rectify this, pilots should:
- Clear the App Cache: This often resets the internal “Ignore” and “Block” lists.
- Review the Pairing List: Ensure that the specific ID number of your Remote Controller (RC) hasn’t been added to a “Blocked” or “Restricted” list within the app’s device manager.
Restoring Factory Communication Protocols
If you cannot find the specific menu to view blocked IDs, a “Reset All Settings” command within the app’s “About” or “Maintenance” tab is often the only way to clear the slate. This removes all filtered hardware IDs, frequency blocks, and Remote ID ignores, returning the drone to its factory-default communication state.

Conclusion
In the modern drone era, the ability to “see what numbers you have blocked” is a sophisticated task that bridges the gap between hardware operation and software management. Whether these numbers represent Remote ID serials, RF channels, or network IP addresses, managing them is key to maintaining a safe, secure, and interference-free flight.
As drone apps continue to become more complex, the “Blocked List” will remain a vital tool for the professional pilot. By mastering the menus of DJI, Autel, and other major manufacturers, you ensure that you are not just flying a drone, but managing a high-performance digital asset with precision and security. Keep your filters clean, your IDs recognized, and your transmission channels open to ensure that every flight is as stable as the technology allows.
