H5 wx.onSearchBeacons 无法使用了？

wx.checkJsApi({

  jsApiList: ["startSearchBeacons", "stopSearchBeacons", "onSearchBeacons"], // 需要检测的JS接口列表，所有JS接口列表见附录2,

  success: function(res) {

console.log(JSON.stringify(res));

  }

});

{"checkResult":{"startSearchBeacons":true,"onSearchBeacons":false,"stopSearchBeacons":true},"errMsg":"checkJsApi:ok"}

onSearchBeacons:false是不是表达onSearchBeacons不能使用了？
