Advertise Manufaturer Data On IOS Devices

问题点： IOS设备对BLE peripheral端发送广播的支持，似乎不允许进行Manufaturer定制广播（central端接受是可以的）。如何在IOS设备上进行Manufaturer Data的广播？

1.  官网对cbperipheral.startAdvertising(_:)描述：

An optional dictionary containing the data you want to advertise. The possible keys of anadvertisementDatadictionary are detailed inCBCentralManagerDelegate. That said, only two of the keys are supported for peripheral manager objects:CBAdvertisementDataLocalNameKeyandCBAdvertisementDataServiceUUIDsKey.

是不可以指定CBAdvertisementDataManufacturerDataKey关键字的。

2. central设备discover扫描到的数据：

centralManager didDiscover

name: nil

UUID: EC2FB599-DCBC-4954-89CB-D579D8DB762A

advertisementData: ["kCBAdvDataIsConnectable": 1, "kCBAdvDataManufacturerData": <0000c0ff 08b31500 0016aba2 699500bf 55343483 60>]

RSSI: -83

central可以扫描出peripheral广播的Manfacturer Data

3. IOS提供的iBeacon是以Manafacturer Data形式向外广播信息

kCBAdvDataAppleBeaconKey =<........>;

用peripheral.strartAdvertising广播CLBeaconRegion应该可以实现广播Manufacturer Data
