Upgrade Introduction:


I. Background of the “One-Key Restore User-Defined Settings” Function

1. Remote Controller Model Data

One remote controller can control multiple devices, such as several model aircraft. Each device requires different parameters, and the controller can store parameters for multiple devices, which are called model data. Model data can be retained even after the controller is powered off.

2. OEM/Customized Parameters

Drone remote controllers are not only used for model aircraft but also widely applied in security inspection vehicles, hoisting equipment in industry, and agricultural fields. OEMs (original equipment manufacturers) need to configure dedicated parameters for each controlled device and deliver them together with the controller to customers.

3. Parameter Management Challenges

For example, a security inspection vehicle manufacturer configures the controller for each vehicle and sells it to users. Users often unintentionally modify the settings, leading to malfunctions. This requires remote assistance or sending the controller back to the OEM for reconfiguration. Although controllers have a one-key parameter restore function, it restores the controller manufacturer’s default parameters, not the OEM-configured/Customized ones.

4. Dual Restore Function

① OEMs/training institutions/Individual users can choose to restore OEM-configured/customized parameters instead of the controller manufacturer’s defaults.

② OEMs/training institutions/Individual users can also choose to restore the controller manufacturer’s default parameters easily.


II. Content of the “One-Key Restore User-Defined Settings” Function

1. Current Model Storage Method

Each model's data is stored as an independent file, located on storage media such as a TF card or EEPROM. This allows user settings to be saved after a power-off. All models share the same factory default settings, which users can restore with one key via the menu.

2. Implementation of the New Function

① On the Remote Controller

Each model is assigned two files, stored separately in the user area and the system area. User modifications are saved in the user area file, while OEM-configured/Customized parameters are saved in the system area file. The one-key restore function no longer restores the controller manufacturer’s parameters but instead restores the OEM’s/customized system parameters. This ensures that if users accidentally change settings, they can restore the OEM/Customized defaults with one key.

② Connecting to a Computer

The remote controller can be connected to a computer in USB drive mode, which not only supports firmware upgrades but also allows access to all model files under the user and system directories.

③ Restoring Parameters

OEMs can configure parameters for each device just like regular users. The parameters are first saved in the corresponding user file (e.g., file No.10 named robot.dat). After connecting the controller to a computer, the user file can be copied over to the corresponding system file (e.g., system file No.10). The one-key restore function then restores the parameters from the system file.


III. Technical Points of the “One-Key Restore User-Defined Settings” Function

1. Dual Files per Model

Each model has two files, one in the user area and one in the system area.

2. File Replacement

By simply replacing files, OEMs can easily implement one-key restore of their parameters without changing the traditional parameter-setting method.

3. Model Numbering

Each model file has a unique identifier for recognition and management, ensuring that the reset can be accurately applied to the designated model.
