最小和最大广告值如何发挥广告间隔的BLE

史提夫，
为澄清的core_v4.2规格，“advertising_interval_min应小于或等于advertising_interval_max，advertising_interval_min和advertising_interval_max不应使控制器确定最佳的广告时段给其他相同的值二活动。“因为广告事件扰动的时间使用advdelay，实际广告间隔不应与价值是相同的，这是与两个值（最大/最小）相同。



     以下为原文
  Steve,
As per clarification in BLE Core_v4.2 spec, "The Advertising_Interval_Min shall be less than or equal to the Advertising_Interval_Max. The Advertising_Interval_Min and Advertising_Interval_Max should not be the same value to enable the Controller to determine the best advertising interval given other activities."
Because advertising events are perturbed in time using advDelay, the actual advertising interval should not be identical with the value, which is set with the two values(max/min) same.

嗨，佛恩，
你能详细说明一下“……确定其他活动的最佳广告间隔”吗？一个例子有助于澄清一些事情。
最好的，
史蒂夫

  Hi fwan,
 
Could you elaborate for us what the documentation means by "...to determine the best advertising interval given other activities"? An example would help clear some things up.
 
Best,
Steve

你好，史提夫，
最小/最大间隔确保广告分组以最少的碰撞损失传输。为了建立连接，中央设备接收广告分组是重要的。如果您以固定速率周期性地发送广告，并且如果有另一个设备发送/使用频道（也可以是Wi-Fi设备）并阻止广告，那么您的设备几乎是无用的。虽然所有3个渠道的固定利率广告可能会提高广告通过的机会。在所有3个通道的随机率发送广告包的机会（这是典型的固定区间随机延迟前广告-最小/最大间隔是确定这些值）更使中央设备的机会。因此，建议有不同的最大和最小间隔。
让我知道这是否有帮助。
当做，

  Hello Steve,
 
The min/max intervals ensure the advertisement packets are transmitted with least collision losses. In order to establish a connection, it is important the central device receives the advertisement packets. If you transmit advertisement periodically at a fixed rate and if there is another device that transmits/uses the channel (can be a Wi-Fi device too) and blocks the advertisement, then your device is almost useless. Though advertising on all 3 channels at fixed rate may improve the chances of the advertisement going through. Still the chances of sending advertisement packets on all 3 channels at random rate (it is typically fixed interval with random delay before advertising - min/max interval is used to determine these values) has more chances of making it to the central device. Hence the recommendation of having different min and max interval.
 
Let me know if this helps.

我喜欢思考的广告时段之一，如果不是最重要的考虑功耗。
连接速度和功率之间存在权衡。你越快的广告装置可以连接…你广告的速度越慢，你节省的力量就越大。

  I like to think about the advertising interval as one of if not the most important power consideration.
 
There is a tradeoff between connection speed and power.  The more you advertise the faster the device can be connected... the slower your advertise the more power you save.
