Firmware Update

Firmware update is the process to flash new firmware to a chip and update the earlier firmware. Tuya supports regular firmware updates to meet your development and market requirements. Tuya also deactivates certain legacy firmware versions in line with chip iterations of the manufacturers. In the case of device feature updates, a firmware update is also required.

Update process

Initialize firmware information

API description

Initializes firmware for devices, such as Wi-Fi devices, Zigbee gateways, cameras, Bluetooth devices, and Bluetooth mesh devices.

IThingOTAService iThingOTAService = ThingHomeSdk.newOTAServiceInstance(devId);

Parameters

Parameter	Description
devId	The device ID.

Get firmware update information

Returns the device update information. The firmware update model ThingSmartFirmwareUpgradeModel provides the following properties:

• type: indicates the firmware update channel type.
• upgradeMode: indicates the firmware update mode.
• typeDesc: describes the firmware type.

Firmware update modes

• Generic firmware update: This is the traditional mode to update device firmware.

• Update PID-specific firmware: This update mode applies the philosophy of products. Update versions can be differentiated by functional modules, such as product schema, panel settings, multilingual settings, and shortcut control.

  The new API methods are required to get the firmware list and trigger a PID-specific firmware updates.

Firmware update channel types

For the generic firmware update mode, when you query a list of firmware updates, the type field of UpgradeInfoBean indicates the type of firmware update channel and typeDesc describes each channel.

The following table lists descriptions of type for a generic firmware update. We recommend that you describe the firmware by using the value of typeDesc that is actually returned by the model.

Channel type of generic firmware update	Description of firmware update channel
0	Main module, Wi-Fi module, and Bluetooth module.
1	Bluetooth module
2	GPRS module
3	Zigbee module
5	433 MHz module
6	NB-IoT module
9	MCU module
10 to 19	Extension module

Start update

API description

// Both generic update and PID-specific update are supported.
// Based on the original update capabilities, Bluetooth LE devices and Bluetooth mesh dynamic gateways are also supported.
// Multiple firmware versions can be sequentially updated for the same device.
void startFirmwareUpgrade(List<UpgradeInfoBean> upgradeInfoBeans);

// Deprecated. startFirmwareUpgrade: is recommended to initiate an update.
// Only generic firmware update is supported. Only Wi-Fi devices and Zigbee sub-devices are supported. Bluetooth LE devices are not supported.
// Only a single firmware update task can be initiated.
// type: the type of update. You can call getFirmwareUpgradeInfo to get the value.
iThingOta.startOta();

Parameters

Field	Type	Description
upgradeInfoBeans	List	You can call getFirmwareUpgradeInfo to get a list of firmware versions.

Example

iThingOTAService.startFirmwareUpgrade(upgradeInfoBeans);

Continue with update

Currently, this API method applies only when the callback for the update progress is returned and when error.code is 5005.

For Wi-Fi devices and combo devices, to ensure a successful update, the minimum signal strength level is specified. When an update is triggered, the system checks whether the device signal strength is within an acceptable range. If not, the callback for the update progress is returned, including error.code = 5005. Then, you can implement a UI interaction for users to make decisions. For example, a dialog box appears, saying “The device signal is weak, and the update might fail. Continue to update?”

API description

void confirmWarningUpgradeTask(String devId, boolean isContinue);

Parameters

Parameter	Description
devId	The device ID.
isContinue	Indicates whether to continue the update task.

Things to note

This process applies to only the update that is initiated by startFirmwareUpgrade:.

Example

// isContinue: asks users whether to continue the update.
iThingOTAService.confirmWarningUpgradeTask(devId",isContinue);

Cancel update

Currently, only low-power devices are supported. After an update is initiated for this type of device, the update task might enter the status of waiting for the device to wake up (upgradeStatus = 5). This API method can be called to cancel the update task in this status.

API description

// Currently, an update task can be canceled only for low-power devices.
void cancelFirmwareUpgrade(int otaType, IResultCallback callback);

Parameters

Parameter	Description
otaType	The type of firmware.
callback	The callback.

Example

iThingOTAService.cancelFirmwareUpgrade(otaType, new IResultCallback() {
    @Override
    public void onError(String code, String error) {

    }

    @Override
    public void onSuccess() {

    }
});

Cancel update when waiting for device to wake up

API description

For low-power devices, after an update is initiated, the update task might enter the status of waiting for the device to wake up (upgradeStatus = 5). This API method can be called to cancel the update task in this status.

void cancelFirmwareUpgrade(IResultCallback callback);

Parameters

Parameter	Description
callback	The callback.

Example

public void cancelDeviceWakeup(final IResultCallback callback) {
    iThingOTAService.cancelFirmwareUpgrade(new IResultCallback() {
        @Override
        public void onError(String code, String error) {
            if (callback != null) {
                callback.onError(code, error);
            }
        }

        @Override
        public void onSuccess() {
            if (callback != null) {
                callback.onSuccess();
            }
        }
    });
}

Listen for callback

Example

iThingOTAService.registerDevOTAListener(new IDevOTAListener() {
    @Override
    public void firmwareUpgradeStatus(ThingDevUpgradeStatusBean upgradeStatusBean) {

    }
});

Automatically update to the latest version

Certain devices support an automatic update to the latest version. You can use DeviceBean - isSupportAutoUpgrade to check whether a device supports this feature.

API description

// Checks whether this feature is enabled.
void getAutoUpgradeSwitchState(IThingDataCallback<Integer> callback);
// Switches between the enabled or disabled states.
void changeAutoUpgradeSwitchState(int state, IResultCallback callback);

Parameters

Parameter	Description
state	The status of the feature. Valid values: 0: disabled 1: enabled
callback	The callback.

Example

public void getAutoUpgradeStatus(final IThingDataCallback<Integer> callback) {
    iThingOTAService.getAutoUpgradeSwitchState(new IThingDataCallback<Integer>() {
        @Override
        public void onSuccess(Integer result) {
            if (callback != null) {
                callback.onSuccess(result);
            }
        }

        @Override
        public void onError(String errorCode, String errorMessage) {
            if (callback != null) {
                callback.onError(errorCode, errorMessage);
            }
        }
    });
}

public void switchAutoUpgradeStatus(int value, final IResultCallback callback) {
    iThingOTAService.changeAutoUpgradeSwitchState(value, new IResultCallback() {
        @Override
        public void onError(String code, String error) {
            if (callback != null) {
                callback.onError(code, error);
            }
        }

        @Override
        public void onSuccess() {
            if (callback != null) {
                callback.onSuccess();
            }
        }
    });
}
