### attach
```cpp
void AutoConnectUpdate::attach(AutoConnect& portal)
```
Attaches the [AutoConnectUpdate](apiupdate.md) to the AutoConnect which constitutes the bedrock of the update process. This function creates a [dialog page](otaserver.md#behavior-of-the-autoconnectupdate-class) for the update operation as an instance of [AutoConnectAux](apiaux.me) and participates in the [AutoConnect menu](menu.md).
- **Parameter**
- portalSpecifies a reference to the AutoConnect instance to attach.
### disable
```cpp
void AutoConnectUpdate::disable(const bool activate)
```
Disable the Update item in [AutoConnect menu](menu.md). The [AutoConnect::disable](#disable) function only hides the Update item from the menu, and the [AutoConnectUpdate](apiupdate.md) class is still active with the parameter condition. You can use the [AutoConnectUpdate::enable](#enable) function to appear it again in the menu.
- **Parameter**
- activateIf specified the **true** then the Update item will be displayed on the [AutoConnect menu](menu.md) and OTA update will be available during the WiFi status is WL_CONNECTED. For the **false**, the OTA update feature is disabled.
### enable
```cpp
void AutoConnectUpdate::enable(void)
```
Makes [AutoConnectUpdate](apiupdate.md) class available by incorporating the OTA update function into the [AutoConnect menu](menu.md). In ordinally, the [AutoConnectUpdate](apiupdate.md) class becomes available by just calling the [AutoConnectUpdate::attach](#attach) function.
