AutoConnectUpdate API

Constructor

AutoConnectUpdate

AutoConnectUpdate(const String& host, const uint16_t port, const String& uri, const int timeout, const uint8_t ledOn)
Parameters
hostUpdate server address. Specifies IP address or FQDN.
portSpecifies HTTP port for the updating process. The default assumes AUTOCONNECT_UPDATE_PORT defined in the AutoConnectDefs.h header file.
uriSpecifies a URI on the update server that has deployed available binary sketch files.
timeoutSpecifies the maximum response time for the update server. The default assumes AUTOCONNECT_UPDATE_TIMEOUT in the AutoConnectDefs.h header file.
ledOnActive signal to light the LED ticker during the update. Specifies HIGH or LOW

The AutoConnectUpdate class inherits from the ESP8266HTTPUpdate (HTTPUpdate for ESP32) class.

Public member functions

attach

void AutoConnectUpdate::attach(AutoConnect& portal)

Attaches the AutoConnectUpdate to the AutoConnect which constitutes the bedrock of the update process. This function creates a dialog page for the update operation as an instance of AutoConnectAux and participates in the AutoConnect menu.

Parameter
portalSpecifies a reference to the AutoConnect instance to attach.

disable

void AutoConnectUpdate::disable(const bool activate)

Disable the Update item in AutoConnect menu. The AutoConnect::disable function only hides the Update item from the menu, and the AutoConnectUpdate class is still active with the parameter condition. You can use the AutoConnectUpdate::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 and OTA update will be available during the WiFi status is WL_CONNECTED. For the false, the OTA update feature is disabled.

enable

void AutoConnectUpdate::enable(void)

Makes AutoConnectUpdate class available by incorporating the OTA update function into the AutoConnect menu. In ordinarily, the AutoConnectUpdate class becomes available by just calling the AutoConnectUpdate::attach function.

handleUpdate

void AutoConnectUpdate::handleUpdate(void)

Performs the update process. This function is called by AutoConnect::handleClient when AutoConnectUpdate is enabled. In many cases, sketches do not need to call this function on purpose.

isEnabled

bool AutoConnectUpdate::isEnabled(void)

Returns whether AutoConnectUpdate is enabled.

rebootOnUpdate

void AutoConnectUpdate::rebootOnUpdate(bool reboot)

Specifies whether or not to automatically restart the module as a result of the successful completion of the update process.

Parameter
rebootIf specified the true then the ESP module will reboot after the updating successfully completed. For the false, The module does not reboot automatically. The uploaded new firmware remains in the updating stage of the flash on the ESP module.
The boot process during the next start turn of the module by reset will copy the updated firmware to the actual program area and a new sketch program will start. The default value is true.

This function inherits from the ESP8266HTTPUpdate (HTTPUpdate for ESP32) class.

setLedPin

void AutoConnectUpdate::setLedPin(int ledPin, uint8_t ledOn)

Sets the port and the ON signal level of the externally connected LED that should act as a ticker during the update process.

Parameter
ledPinSpecifies the PIN connected external LED for the ticker. The default assumes AUTOCONNECT_TICKER_PORT defined in the AutoConnectDefs.h header file and it is derived from the board-specific LED_BUILTIN. By default, the AutoConnectUpdate class does not use the ticker for boards without the LED_BUILTIN definition. If you connect the ticker LED externally, you need to specify the PIN using the setLedPin function.
ledOnSpecifies the the ON signal level of the LED PIN port. It is HIGH or LOW.

This function inherits from the ESP8266HTTPUpdate (HTTPUpdate for ESP32) class.

status

AC_UPDATESTATUS_t AutoConnectUpdate::status(void)

Returns the update process status transition indicator as an enumerated value of the AC_UPDATESTATUS_t type that indicates the process status of the AutoConnectUpdate class.

Return value
One of the enumerated values ‚Äč‚Äčindicating the status of the Update class as follows:

  • UPDATE_RESET : Update process ended, need to reset.
  • UPDATE_IDLE : Update process has not started.
  • UPDATE_START : Update process has been started.
  • UPDATE_PROGRESS : Update process has been started.
  • UPDATE_SUCCESS : Update successfully completed.
  • UPDATE_NOAVAIL : No available update.
  • UPDATE_FAIL : Update failed.
