- --- 模块功能:wifi扫描功能
- -- 支持wifi热点扫描
- -- @module wifiScan
- -- @author openLuat
- -- @license MIT
- -- @copyright openLuat
- -- @release 2020.5.21
- require"sys"
- module(..., package.seeall)
- local sCbFnc
- --- wifi扫描热点请求
- -- @function cbFnc 扫描到热点返回或者超时未返回的回调函数,回调函数的调用形式为:
- -- cbFnc(result,cnt,info)
- -- result:true或者false,true表示扫描成功,false表示扫描失败或者超时失败
- -- cnt:number类型,表示扫描到的热点个数
- -- info:table或者nil类型;result为false时,为nil;result为true时,表示扫码到的热点mac和信号信息,table类型,例如:
- -- {
- -- ["1a:fe:34:9e:a1:77"] = -63,
- -- ["8c:be:be:2d:cd:e9"] = -81,
- -- ["20:4e:7f:82:c2:c4"] = -70,
- -- }
- -- @number[opt=10000] timeout 等待扫描热点返回的超时时间,单位毫秒,默认为10秒
- -- @usage
- -- wifiScan.request(cbFnc)
- -- wifiScan.request(cbFnc,5000)
- function request(cbFnc,timeout)
- sCbFnc = cbFnc
- sys.timerStart(sCbFnc,timeout or 10000,false)
