Source: https://developers.weixin.qq.com/miniprogram/dev/framework/performance/api-frequency.html

此代码片段展示了 wx.getSetting 的正确用法，通过缓存接口返回结果并在需要时检查权限，避免不必要的频繁调用。

```javascript
let setting
wx.getSetting({
  success(res) {
    setting = res
  }
})

// 在需要获取地理位置时
if (setting.authSetting['scope.userLocation']) {
  wx.getLocation({
    success(res) {},
    fail(res) {
      if (res.errMsg.indexOf('auth deny') >= 0) {
        // 如果权限没有开，引导用户打开设置页开启地理位置授权
      }
    }
  })
}
```

连接成功后，调用 `wx.getBLEDeviceServices` 获取设备提供的所有服务。开发者可以根据业务需求选择一个主服务进行后续通信。

```javascript
wx.getBLEDeviceServices({
  deviceId, // 搜索到设备的 deviceId
  success: (res) => {
    for (let i = 0; i < res.services.length; i++) {
      if (res.services[i].isPrimary) {
        // 可根据具体业务需要，选择一个主服务进行通信
      }
    }
  }
})
