[英]What the relation between Immediate Alert Service and Proximity profile in BLE(Bluetooth 4.0)?
I am new to iOS development, and study about Bluetooth Low Energy (BLE, Bluetooth 4.0) for IOS 我是iOS开发的新手,并为IOS研究蓝牙低功耗(BLE,蓝牙4.0)
I have found the information like Proximity profile and it use the Service
of Immediate Alert
. 我找到了像Proximity profile这样的信息,它使用了
Immediate Alert
Service
。 The description of Proximity profile
is like the following: Proximity profile
的描述如下:
When a device moves away from a peer device so that the connection is dropped or the path loss increases above a preset level, causing an immediate alert.
The condition-A:Using Proximity profile
条件-A:使用
Proximity profile
The Proximity profile
use immediate alert Service
to start alert when a device moves away from a peer device. 当设备离开对等设备时,
Proximity profile
使用immediate alert Service
来启动警报。
The condition-B:Without using Proximity profile
条件-B:不使用
Proximity profile
I can get the RSSI
from the BLE device
and use the immediate alert Service
to start alert when the RSSI
is out of range which I have setting(For example: -75dbm). 我可以从
BLE device
获取RSSI
并使用immediate alert Service
在RSSI
超出我设置的范围时启动警报(例如:-75dbm)。
The question is like the following:
What the different between condition-A
and condition-B
?? condition-A
和condition-B
之间有什么不同?
Is the Profile
just a theory ? Profile
只是一个理论吗? and the Service
is the real application ? 而
Service
是真正的应用程序?
该配置文件定义了服务的语义,而服务只包含其包含的特征的正式描述,并具有指定的UUID。
