How to Mirror a DJI Drone to an External Monitor

Not every drone controller includes direct HDMI output.

Many modern drones use a phone or tablet running the flight app to display the live feed. In these cases, BOB Air Command™ can still be used as a larger outdoor display by using wireless screen mirroring.

This setup is ideal for drone pilots who want a bigger, daylight-viewable screen when flying in the field.

How Wireless Mirroring Works

In a wireless setup, the live drone feed appears on your phone or tablet through the drone flight app.

That mobile device then mirrors its screen to BOB Air Command™ using a wireless display adapter connected to the monitor.

Basic signal flow

Drone→ Phone / Tablet running flight app→ WiFi screen mirroring→ Wireless display adapter→ BOB Air Command™

This allows you to view your flight feed on a larger screen without requiring a controller with HDMI output.

What You Need

To set up wireless screen mirroring with BOB Air Command™, you will typically need:

• BOB Air Command™

• A compatible drone

• A phone or tablet running the drone flight app

• A wireless display adapter

• A power source for Air Command

• A WiFi connection or local wireless link for casting

Depending on your setup, you may also want a portable router or hotspot for more reliable field use.

Step-by-Step Setup

1. Power On BOB Air Command™

Connect Air Command to your power source and turn on the monitor.

Make sure the monitor is set to the correct HDMI input.

2. Connect the Wireless Display Adapter

Plug your wireless display adapter into the HDMI input on BOB Air Command™.

If the adapter requires USB power, connect that as well.

Once powered, the adapter should begin broadcasting or preparing for connection.

3. Launch the Drone Flight App

Turn on your drone and connect your phone or tablet as you normally would.

Open the drone flight app and confirm that your live feed is working properly on the mobile device first.

Do not try to mirror before you confirm the app is running correctly.

4. Connect Your Phone or Tablet to the Display Adapter

Use your device’s built-in screen mirroring / casting feature to connect to the wireless display adapter.

Once connected, your phone or tablet screen should appear on BOB Air Command™.

At that point, whatever appears in your drone flight app will also appear on the monitor.

5. Adjust for Field Use

Once the image is visible on Air Command:

• Increase screen brightness as needed

• Position the case for the best viewing angle

• Secure cables and accessories

• Confirm connection stability before flight

This gives you a larger, more visible display for outdoor operation.

Why WiFi Matters

Wireless mirroring depends on a stable wireless connection between your mobile device and the display adapter.

In some cases this is a direct local connection. In others, your setup may work better with an available WiFi network or portable hotspot.

In remote locations, unstable wireless connections can interrupt mirroring or make setup more difficult.

That is why field connectivity matters.

Why BOB Relay™ Is Important

BOB Relay™ helps solve the biggest challenge with wireless field setups: portable connectivity and power.

When you’re away from home, the office, or reliable local internet, Relay can support the devices that make wireless workflows easier to use in the field.

Relay can power and support equipment such as:

• Starlink Mini

• Portable routers

• Mobile hotspots

• Wireless display adapters

• Phones and tablets used for flight apps

This allows you to create a more reliable portable field network for drone operations, inspections, and remote work.

Example field workflow

Drone→ Phone / Tablet→ WiFi / Mirroring→ BOB Air Command™

With Relay supporting the network and power side of the setup, you can operate more confidently in remote environments.

Direct HDMI vs Wireless Mirroring

Direct HDMI

Best for the lowest latency and most reliable connection.

Recommended when using controllers with native HDMI output.

Wireless Mirroring

A flexible option for drones that rely on a phone or tablet.

Best for users who want a larger display but do not have HDMI output on the controller.

Both methods allow Air Command to function as a portable outdoor monitoring station, but direct HDMI is the preferred connection whenever available.

Best Use Cases for Wireless Mirroring

Wireless screen mirroring is especially useful for:

• DJI Mini series users

• DJI Air series users

• Casual and prosumer drone pilots

• Field teams who want a second viewing screen

• Outdoor operators who need a larger display without changing controllers

It can also be useful for demonstrations, client viewing, and team collaboration in the field.

Pro Tips

• Test your wireless setup before heading into the field

• Confirm your display adapter is compatible with your phone or tablet

• Make sure Air Command is set to the correct input

• Use direct HDMI when possible for the most stable performance

• Use Relay when you need portable power and better field connectivity

Build a Better Field Setup

BOB Air Command™ gives you a rugged, daylight-viewable outdoor display.

BOB Relay™ helps power and support the field connectivity that wireless workflows often require.

Together, they create a more capable mobile setup for drone operations, inspections, and remote field work.

Air Command shows you the mission. Relay helps keep the system connected.
