P2P Download from Robot Vacuums

A robot vacuum that supports peer-to-peer (P2P) capabilities provides P2P download channels. Map data and cleaning routes are directly transmitted from the robot vacuum to the app through P2P channels. The data does not need to be uploaded to a cloud storage server for downloading. Therefore, data transmission becomes more efficient at a lower cost of cloud storage.

Entry to the feature

ITuyaSweeperKitSdk iTuyaSweeperKitSdk = TuyaOptimusSdk.getManager(ITuyaSweeperKitSdk.class);

ITuyaSweeperP2P tuyaSweeperP2P = iTuyaSweeperKitSdk.getSweeperP2PInstance(devId);

Access the P2P service

API description

/**
*
* @param callback The callback that is executed when a P2P connection is created.
*/
void connectDeviceByP2P( SweeperP2PCallback callback);

Parameters

Example

tuyaSweeperP2P.connectDeviceByP2P(new SweeperP2PCallback() {
    @Override
    public void onSuccess() {
            // The success callback.
            }

    @Override
    public void onFailure(int i) {
            // The failure callback.
            }
            });

Enable P2P downloading

API description

Enable file transmission after the success callback of connectDeviceByP2P. If a P2P connection is closed unexpectedly, a failure callback is executed. For more information about the error codes, see Error codes. The failure callback indicates that the device might have a network exception. To fix the problem, you can call connectDeviceByP2P to try to reconnect the device.

/**
*
* @param downloadType     The method to download data.
* @param callback         The callback that is executed when P2P downloading is enabled.
* @param callback2        The callback for P2P data.
*/
void startObserverSweeperDataByP2P(DownloadType downloadType, SweeperP2PCallback callback, SweeperP2PDataCallback callback2);

Parameters

Parameters of SweeperP2PBean

Example

tuyaSweeperP2P.startObserverSweeperDataByP2P(DownloadType.P2PDownloadTypeOnce, new SweeperP2PCallback() {
    @Override
    public void onSuccess() {
            // The success callback.
            }

    @Override
    public void onFailure(int i) {
            // The failure callback.
            }
            }, new SweeperP2PDataCallback() {
    @Override
    public void receiveData(int type, @Nullable SweeperP2PBean sweeperP2PBean) {
            // The callback that is executed when data is received through P2P connections. `type` indicates the type of received data.
            }

    @Override
    public void onFailure(int i) {
            // The failure callback.
            }
            });

Disable P2P downloading

Pauses data transmission through P2P channels, but retains P2P channels. You can call startObserverSweeperDataByP2P to continue downloading data.

/**
*
* @param callback         The callback that is executed when P2P downloading is disabled.
*/
void stopObserverSweeperDataByP2P(SweeperP2PCallback callback);

Parameters

Example

tuyaSweeperP2P.stopObserverSweeperDataByP2P(new SweeperP2PCallback() {
    @Override
    public void onSuccess() {
            // The success callback.
            }

    @Override
    public void onFailure(int i) {
            // The failure callback.
            }
            });

Check P2P connection status

/**
* Checks P2P connection status.
*/
boolan checkP2PActive();

Example

tuyaSweeperP2P.checkP2PActive();

Disable the P2P service

Stops downloading data, destroys P2P channels, and releases the occupied memory and thread resources.

/**
*
* @param callback         The callback that is executed when P2P downloading is disabled.
*/
void onDestroyP2P();

Example

tuyaSweeperP2P.onDestroyP2P();

FAQs

• Problem: The SweeperP2PCallback API method or the SweeperP2PCallback class is marked in red and cannot be found. The arr file of the dependency library is found. But the following error message is returned:

  // This class file was compiled with different version of Kotlin compiler and can't be decompiled.
  // Current compiler ABI version is 1.1.16
  // File ABI version is 1.5.1
  

• Solution: Try to update the Kotlin version of Android Studio at Preferences > Languages & Framework > Kotlin.
