cl.location.1 Addition of APIs for Obtaining the Wi-Fi and Bluetooth Scanning Result

APIs for obtaining the Wi-Fi and Bluetooth scanning result are added to @ohos.geoLocationManager.d.ts. They are all system APIs.

Change Impact

The system application can use the Wi-Fi and Bluetooth scanning result obtained by these APIs for network positioning.

Key API/Component Changes

Class	API Type	Declaration	Change Type
geoLocationManager	method	function on(type: 'locatingRequiredDataChange', config: LocatingRequiredDataConfig, callback: Callback<Array<LocatingRequiredData>>): void;	Added
geoLocationManager	method	function off(type: 'locatingRequiredDataChange', callback?: Callback<Array<LocatingRequiredData>>): void;	Added
geoLocationManager	method	function getLocatingRequiredData(config: LocatingRequiredDataConfig): Promise<Array<LocatingRequiredData>>;	Added

Adaptation Guide

The following example shows how to obtain Wi-Fi and Bluetooth scanning information at a time:

import geoLocationManager from '@ohos.geoLocationManager';
let config = {'type': 1, 'needStartScan': true, 'scanInterval': 10000};
try {
    geoLocationManager.getLocatingRequiredData(config).then((result) => {
        console.log('getLocatingRequiredData return: ' + JSON.stringify(result));
    })  
    .catch((error) => {
        console.log('promise, getLocatingRequiredData: error=' + JSON.stringify(error));
    });
} catch (err) {
    console.error("errCode:" + err.code + ",errMessage:" + err.message);
}
