Core Basic Features Factory Reset

Factory Reset

The factory reset operation restores the device to its original factory settings, erasing all user data and custom configurations. This operation is useful when preparing a device for resale or troubleshooting persistent issues.

Prerequisites

Before performing a factory reset, ensure:

• The device is connected and in a stable state
• All important data has been backed up
• The user understands that all personal data will be erased

API Reference

Framework

AIBuds.xcframework

Import

In the files where you want to use the SDK, import the main header:

Swift

import AIBuds

Objective-C

#import <AIBuds/AIBuds.h>
#import <AIBuds/AIBuds-Swift.h>

Protocol

The factoryReset method is defined in the following protocol. The protocol inherits from the base device API protocol.

Swift

/// Defines common device operations including factory reset
protocol DeviceCommonAPI: DeviceAPI {
    /// Factory reset
    /// - Parameters:
    ///   - completion: Completion callback that returns the operation result
    ///     - success: `true` if the operation was successful; otherwise `false`.
    ///     - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.
    func factoryReset(_ completion: AIBudsCompletionHandler?)
}

Objective-C

/// Defines common device operations including factory reset
@protocol AIBudsDeviceCommonAPI <AIBudsDeviceAPI>
/// Factory reset
/// - Parameters:
///   - completion: Completion callback that returns the operation result
///     - success: `true` if the operation was successful; otherwise `false`.
///     - error: An `NSError` object that describes the error that occurred, or `nil` if the
///     operation was successful.
- (void)factoryResetWithCompletion:(AIBudsCompletionHandler)completion;
@end

Instance Method

Restores the device to its original factory settings, erasing all user data and custom configurations.

iOS 13.0+

Swift

/// Factory reset
/// - Parameters:
///   - completion: Completion callback that returns the operation result
///     - success: `true` if the operation was successful; otherwise `false`.
///     - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.
func factoryReset(_ completion: AIBudsCompletionHandler?)

Objective-C

/// Factory reset
/// - Parameters:
///   - completion: Completion callback that returns the operation result
///     - success: `true` if the operation was successful; otherwise `false`.
///     - error: An `NSError` object that describes the error that occurred, or `nil` if the
///     operation was successful.
- (void)factoryResetWithCompletion:(AIBudsCompletionHandler)completion;

Parameters

Parameter	Type	Description
completion	AIBudsCompletionHandler?	Optional completion callback that is called when the operation completes.

Callback Parameters:

Name	Type	Description
success	Bool	true if the operation succeeded, false otherwise.
error	NSError?	Contains error information if the operation failed, nil otherwise.

Return Value

This method does not return a value directly. The result is provided through the completion callback.

Usage Examples

Swift

import AIBuds

class DeviceManager {

    /// The connected device
    weak var device: DeviceConvertible?

    /// Performs factory reset on the connected device
    func performFactoryReset() {
        // Ensure the device supports factory reset protocol
        guard let device = device as? DeviceCommonAPI else {
            print("Device does not support factory reset")
            return
        }

        // Execute factory reset with completion handler
        device.factoryReset { [weak self] success, error in
            // Handle failure case
            if !success {
                let errorMessage = {
                    if let error = error {
                        return "\(error)"
                    }
                    return "Unknown error"
                }()
                print("Factory reset failed: \(errorMessage)")
                return
            }
            // Handle success case
            print("Factory reset completed successfully")
        }
    }
}

Objective-C

#import <AIBuds/AIBuds.h>

@interface DeviceManager ()

/// The connected device
@property(weak, nonatomic) id<AIBudsDeviceConvertible> device;

@end

@implementation DeviceManager

- (void)performFactoryReset {
    __weak typeof(self) weakSelf = self;

    id<AIBudsDeviceCommonAPI> device = (id<AIBudsDeviceCommonAPI>)self.device;
    // Ensure the device supports factory reset protocol
    if ([device conformsToProtocol:@protocol(AIBudsDeviceCommonAPI)]) {
        // Execute factory reset with completion handler
        [device factoryResetWithCompletion:^(BOOL success, NSError *_Nullable error) {
            // Handle failure case
            if (!success) {
                NSLog(@"Factory reset failed: %@", error);
                return;
            }
            // Handle success case
            NSLog(@"Factory reset completed successfully");
        }];
    }
}

@end

Error Handling

The completion handler may return the following error types:

Error Domain: AIBudsSDK.ErrorDomain

Swift

Error Code	Description	Recovery Suggestion
.deviceNotConnected	Device is not connected	Ensure device is paired and connected
.bleCommandExecFailedDueToTimeout	Operation timed out	Retry the operation
.deviceBusy	Device is busy with another operation	Wait for ongoing operations to complete
.deviceNotSupport	Factory reset is not supported on this device	Check device capabilities before calling

Objective-C

Error Code	Description	Recovery Suggestion
AIBudsSdkErrorCodeDeviceNotConnected	Device is not connected	Ensure device is paired and connected
AIBudsSdkErrorCodeBleCommandExecFailedDueToTimeout	Operation timed out	Retry the operation
AIBudsSdkErrorCodeDeviceBusy	Device is busy with another operation	Wait for ongoing operations to complete
AIBudsSdkErrorCodeDeviceNotSupport	Factory reset is not supported on this device	Check device capabilities before calling

Best Practices

1. Confirm with User: Always display a confirmation dialog before initiating a factory reset, as this operation is irreversible.

2. Handle Background Execution: Wrap the completion handler in a DispatchQueue.main.async block when updating UI.

3. Weak Self Reference: Use [weak self] in the completion handler to prevent retain cycles.

4. Check Protocol Conformance: Verify the device conforms to DeviceCommonAPI protocol before calling the method.

5. Clean Up References: After a successful factory reset, you may need to re-pair the device.

Notes

• Factory reset may take several seconds to complete
• The device will disconnect and reset during this operation
• All user data including paired devices, settings, and stored media will be erased
• The device will restart automatically after the reset completes
