Local Reset

This topic describes how local reset works on Bluetooth sub-devices.

Concepts

Restore a device to factory settings locally by a button press or command, with the pairing information deleted. After a local reset, the device becomes unpaired.

Data structure

tuya_ble_reset_type_t

typedef enum {
    RESET_TYPE_UNBIND,
    RESET_TYPE_FACTORY_RESET,
} tuya_ble_reset_type_t;

• RESET_TYPE_UNBIND: Local unbinding.

• RESET_TYPE_FACTORY_RESET: Local factory reset.

tuya_ble_unbind_reset_response_data_t

typedef struct {
    tuya_ble_reset_type_t type;
    UINT8_T status;     //0-succeed,1-failed.
} tuya_ble_unbind_reset_response_data_t;

• type: See tuya_ble_reset_type_t.

• status: 0 indicates success. 1 indicates failure.

API description

Local unbinding

API description

When a locally unbound device is paired again, its information in the cloud remains intact.

tuya_ble_status_t tuya_ble_device_unbind(VOID_T);

Local factory reset

API description

When a locally reset device is paired again, its information in the cloud is cleared.

tuya_ble_status_t tuya_ble_device_factory_reset(VOID_T);

Trigger event

case TUYA_BLE_CB_EVT_UNBIND_RESET_RESPONSE: {
    if (event->reset_response_data.type == RESET_TYPE_UNBIND) {
        if (event->reset_response_data.status == 0) {
            // Event triggered by local unbinding.
        }
    } else if (event->reset_response_data.type == RESET_TYPE_FACTORY_RESET) {
        if (event->reset_response_data.status == 0) {
            // Event triggered by local factory reset.
        }
    }
} break;

Functional testing

Prerequisites

• You have installed the Tuya app on your phone.
• Your device has been paired.

Procedure

Communicate with the mobile app using a host that simulates a real device.

Local unbinding

Local factory reset

If you have any problems with host usage, see Logic Host User Guide.
