Wi-Fi Subsystem Changelog

cl.wifi.1 Change of the Name of the API for Obtaining Wi-Fi Scan Result

The name of the API for obtaining Wi-Fi scan result is changed in API version 10 Beta1 and then changed to the names used in API version 9 release.

Change Impact

The JS API name needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.

Key API/Component Changes

Involved API:

getScanInfoList(): Array;

Before change:

getScanInfoList(): Array<WifiScanInfo>;

After change:

getScanResults(): Array<WifiScanInfo>;
getScanResultsSync(): Array<WifiScanInfo>;

Adaptation Guide

Example: - Call getScanResults.

function getScanResultsPromise() {
  let methodName = `${tag} getScanResultsPromise`
  wifiManager.getScanResults((err, data) => {
    if (err) {
      showToastE(`${methodName} failed ${JSON.stringify(err)}`)
      return
    }
    if (data == null||data.length == 0) {
      showToast(`${methodName} end data is null`)
      return;
    }
  })
}

Call getScanResultsSync. js function getScanResultsSync(): Array<wifiManager.WifiScanInfo> { let methodName = `${tag} getScanResultsSync` try { return wifiManager.getScanResultsSync(); } catch (error) { showToastE(`${methodName} failed ${JSON.stringify(error)}`) } return Array(); }

cl.wifi.2 Change of Wi-Fi P2P APIs

The names of P2P APIs are changed in API version 10 Beta1 and then changed to the names used in API version 9 release.

Change Impact

The JS API name needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
