Check for Firmware Updates

The current Harmony SDK performs upgrades over BLE OTA. Before checking, the advertisement must declare OTA support, the device must have a cloud Device ID, and current hardware and software versions must be readable.

checkUpdate

import {
  GizCheckUpdateResultInfo,
  GizOTAFirmwareType,
} from '@gizwits/smart-sdk';
 
const update: GizCheckUpdateResultInfo = await device.bleCapability.checkUpdate(
  device,
  GizOTAFirmwareType.MCU
);
 
const hasUpdate: boolean = update.downloadUrl.length > 0;

MODULE identifies communication-module firmware and MCU identifies device MCU firmware. Update ArkUI from the result or exception when no release is available, device data is incomplete, or the request fails.
