Bluetooth controlled drone

Types of Bluetooth controlled drones

Bluetooth-controlled drones are unmanned aerial vehicles that are operated via Bluetooth technology instead of Wi-Fi or radio transmitters. They are also known as Bluetooth drones. They are encrypted, low-power wireless communications that link to a smartphone or tablet from which the drone can be controlled via an app. The range of these drones is within the range of normal Bluetooth technology, which is approximately 10-30 meters maximum. There are several types of Bluetooth-controlled drones depending on various features of the drone;

• Camera drones:

  These are drones that are equipped with cameras on board that can be controlled via Bluetooth from a smart device. The pictures and video footage taken can be stored in an SD card or on the device remotely. Drones with Bluetooth cameras can take aerial photography completely hands-free without a photographer, and they can also capture panoramic views or photojournalism videos. The cameras on the drones can be high-definition (HD) 1080p or even 4K. Some models allow the recording of videos as long as 30 minutes. Drone camera models can vary from 1 megapixel (MP) to up to 12 MP. Alternative storage options for pictures and video footage include USB keys or cloud-based storage options. Drone apps can also be used to edit the media directly on the smart device. Examples of Bluetooth camera drones include the Holy Stone HS510 GPS Drone and the Potensic D88.

• Long range drones:

  These are the types of drones that can fly farther than the average Bluetooth range. These long-range drones circumvent the limitation of the normal Bluetooth range with technological innovation in design. They vent most of the drone's payload, which consists of the transmitter antenna, into the air, and they also integrate stronger antennas. Their design allows for a clear line of sight that helps expand communication ranges. These long-range drones are ideal for mapping and surveying activities. For these purposes, LIDAR can also be used for mapping, and photogrammetry can be utilized for precise Digital Elevation Models (DEMs) for agricultural use near the planting area. This can be done at a quicker pace, thus saving time and enhancing productivity.

• Foldable drones:

  Bluetooth-controlled foldable drones are compact in nature and can be folded. When the drone is folded, it becomes smaller, thus making it portable and convenient to carry anywhere. These drones usually have a camera and can be non-foldable or foldable based on their design. When buying a drone, if portability is a major deciding factor, then a foldable drone would be the right choice.

• Beginner-friendly drones:

  Bluetooth-controlled drones that have easy controls and settings are ideal for beginners. They can learn how to fly with these simple drones and then advance to flying more complicated drones once they have attained proficiency in handling drones. Beginner-friendly drones usually come with added protective features. These features allow the drone to be protected from the inevitable crashes and bumps that may occur while the flight operator is still learning how to control it. These beginner-friendly drones cost less and are more economical for beginners.

• Outdoor drones:

  Drones that are controlled via Bluetooth and are intended for outdoor use are designed to withstand wind and moisture. This weatherproof drone can fly in light rain and stable under light winds. Since these drones are designed for outdoor use, they usually come with cameras and longer flight times. The longer flight times allow for the covering of more distances. The high-quality build will also enable the drone to be used for a longer term. These drones can be used for mapping, surveying, and monitoring tasks over larger areas.

Functions and Features of Bluetooth Controlled Drone

When comparing Bluetooth-controlled drones to traditional RF-controlled drones, the former offers many benefits.

• Range: The range is one of the most important factors for any drone. Traditional RF controllers have a limited range of about 50 to 100 meters, depending on the model and surroundings. If the drone goes beyond this range, it loses signal and may drop. On the other hand, Bluetooth drones have a farther flight range, typically over 200 meters. This is because the drone's RF signal is strong and stable.
• Interference and dropouts: RF signals may interfere with other electronic devices, so RF-controlled drones may have unpredictable behavior if flown near wireless devices. This issue is minimized in drones controlled by Bluetooth technology because Bluetooth's frequency-hopping spread spectrum (FHSS) mitigates interference from other signals.
• Connectivity: Bluetooth technology allows enthusiasts to pilot drones using smart devices such as smartphones and tablets. This increases accessibility and makes it easier for users to connect with their drones. It also allows users to tether their devices to the drone controller.
• Check and upgrade firmware: Bluetooth-controlled drones make it easier to check and update the drone’s firmware via a smartphone app. This helps to improve the drone’s performance and stability.
• Flight data and diagnostics: Such drones allow access to real-time flight telemetry data like altitude, speed, battery status, and more. This information is useful for flight analysis and troubleshooting. Some drones even offer diagnostics tools for maintenance.
• Extended control range: By using a mobile device as a controller, users can extend the control range of the drone, so long as one stays within range of the drone's wireless signal.
• Customizable controls: Drone apps often provide customizable control schemes that allow users to tailor their control experience to preferences. This gives more flexibility and personalization than traditional RF controllers.

Generally, drone-controlled Bluetooth models offer a better user experience. Below are more features of Bluetooth-controlled drones:

• Camera: Some models come with HD cameras for stunning aerial shots. Some even have FPV (first-person view), which allows users to see what the drone sees in real-time.
• GPS-assisted flight: These drones use GPS signals for precise positioning and navigation. This helps to improve flight stability and increases the possibility of returning home (drone automatically returns to the takeoff point) and waypoint planning (setting a series of locations for the drone to fly to).
• Drone live view: Users can watch a live video feed from the drone's camera on a smartphone or tablet while it's in the air. Drone live view improves the overall piloting experience and makes capturing video footage easier and more accessible.
• App control: In most cases, these drones can be controlled entirely through a companion app on a mobile device. The app-based control interface replaces physical remote controllers and allows users to maneuver the drone, adjust camera settings, and access flight modes through touch controls on their smartphones or tablets.

Scenarios

• Recreational Flying and Drone Racing :

  Bluetooth-controlled drones can provide a thrilling flying experience. One can use it to race against friends or just to show off piloting skills in a competitive setting. With drones becoming increasingly popular, there are now professional racing leagues where pilots compete for cash prizes. These events are usually held in large stadiums and are televised worldwide.

• Aerial Photography and Videography:

  Some drone enthusiasts take their drones out to scenic locations and attach cameras to them in order to capture stunning aerial footage. This has created a new genre of filmmaking known as drone cinematography. In recent years, cinematographers have started using drones to shoot commercials, music videos, and even feature films. As a result, the demand for good-quality cameras on drones has increased tremendously.

• SURVEILLANCE AND MONITORING:

  Operators can control drones with Bluetooth technology to keep an eye out for suspicious activity. This can be done by setting up a perimeter and then flying the drone around it to scan the area.

These drones can create detailed maps or perform inspections of hard-to-reach areas, such as roofs, power lines, and pipelines. Several industries, including construction, agriculture, and energy, use them to increase efficiency and reduce costs.

How to Choose Bluetooth Controlled Drones

When choosing a Bluetooth drone, several factors should be considered to ensure it meets specific requirements and provides optimal performance. Here are some key points to remember when selecting a Bluetooth-controlled drone;

• Range: The drone's range and control distance are significantly impacted by Bluetooth technology. Typical Bluetooth controller drones have a range of less than 30m (100 feet), which is much smaller than 2.4GHz WiFi drones. Because of this, most Bluetooth drones are suited for indoor flight or short-range outdoor flight.
• Flight Time: The period refers to how long the drone can fly on a single charge. Smaller drones that weigh less than 0.55 lbs. often fly for 5-7 minutes before needing to recharge or change their batteries. Larger drones with more powerful engines can stay in the air for 20–25 minutes. Longer flight times give Bluetooth-controlled drones more time for exploration and gaming, albeit models with longer ranges typically cost more money.
• Camera Quality: Numerous Bluetooth-enabled toy drones come equipped with cameras. The quality of the pictures and videos that the drone can capture may be significantly impacted by the camera's resolution and features, such like FPV (first-person view) capability and image stabilization. Buyers should choose drone camera models that strike a good balance between cost and Bluetooth-controlled drone camera quality.
• Size and Weight: Drones' size and weight can significantly impact their performance, portability, and ease of use. Larger drones usually have more powerful engines and can carry heavier payloads (like cameras), but they're also less portable and more difficult to fly. Buyers should select a drone size and weight that meets specified needs and preferences.
• Durability & Battery Charging: To ensure maximum resilience against crashes and lengthy (10 mins or more) flight periods, look for drones constructed out of strong plastic with metal supports and brushless motor propellers. Check whether spare batteries are available, as repeated use will soon deplete a drone's battery. If so, ensure they have the opportunity to refuel between usage sessions.
• Price: Price is, of course, one of the most important factors when buying a drone. Buyers must weigh the drone's price against its features, performance, and durability to find one that offers the best value for money.
