verifyUpdate

Compares the firmware of the connected printer and the firmware image specified in updateFirmware.

Execute this API after executing updateFirmware, and make sure the printer firmware has been rewritten to the firmware image specified in updateFirmware.

The execution result of this API is notified to the callback method specified in the delegate parameter.

Syntax

	- (int) verifyUpdate: (Epos2FirmwareInfo *) targetFirmwareInfo delegate: (id<Epos2VerifyeUpdateDelegate>) delegate;

Parameter

targetFirmwareInfo

Specifies the firmware image of the version to be applied to the printer from the list acquired in downloadFirmwareList.

Specifies the same firmware image as that specified in the targetFirmwareInfo parameter of updateFirmware.

delegate

Registers the callback method that returns the processing result of this API.

	- (void) onUpdateVerify:(int)code;

code
The processing result is stored.

Error status	Description
EPOS2_CODE_SUCCESS	Processed successfully.
EPOS2_CODE_ERR_DIFFERENT_MODEL	The corresponding model of the firmware image specified in targetFirmwareInfo, and the model name of the connected printer are different.
EPOS2_CODE_ERR_DIFFERENT_VERSION	The version of the firmware image specified in targetFirmwareInfo, and the firmware version of the connected printer are different.
EPOS2_CODE_ERR_PARAM	An invalid parameter was passed.
EPOS2_CODE_ERR_MEMORY	Memory necessary for processing could not be allocated.
EPOS2_CODE_ERR_TIMEOUT	The process did not end within the specified time period.
EPOS2_CODE_ERR_DATA_CORRUPTED	The firmware image is corrupted.
EPOS2_CODE_ERR_PROCESSING	Could not run the process.
EPOS2_CODE_ERR_ILLEGAL	This API was called while no communication had been started.
EPOS2_CODE_ERR_FAILURE	An unknown error occurred.

Return value

Error status	Description
EPOS2_SUCCESS	The function was executed successfully.
EPOS2_ERR_PARAM	An invalid parameter was passed. This API was called when updateFirmware had not been executed.
EPOS2_ERR_FAILURE	An unknown error occurred.

Supplementary explanation

This API can be used in an environment that can be connected to both the Internet and the printer.

This API cannot be used simultaneously with other APIs.
After executing this API, do not execute any other API until the callback is returned.

Do not turn off the power supply to the printer while executing this API.

This API can be used in the system configuration of the TM printer model and customer display model.
With the system configuration of the TM Printer + DM-D + barcode scanner model, this API can be used when connecting via Bluetooth or USB.

This API cannot be used with SSL/TLS communication.
Since it takes time to send and receive large amounts of data over BLE connection, this API cannot be used with BLE connection.
Connect to only Printer class when executing this API.
