我需要调整与''相关的广告间隔（最小/最大）''命令在UM1755 BlueNRG蓝牙LE堆栈ACI用户手册的第30-31页描述（在BlueNRG产品页面上链接）。该命令具有以下参数： 在哪里我需要了解和的细节。但是没有提供细节。用户手册说明了这些参数： 在命令参数的详细列表中，这两个参数完全缺失！能否提供这两个参数的详细信息：和 每个字节多少？如果＆gt; 1个字节是大字还是小字节？什么是时间单位？换句话说，如果我指定一个值1（十进制），相应的广告间隔是什么？如果这个信息在某处可用，请指出它。非常感谢你！ #adv_interval_min＃advertising-interval #adv_interval_max #bluehci_gap_set_limited_discoverable以上来自于谷歌翻译以下为原文 I need to adjust the Advertising Intervals (min/max) associated with the '''' command which is described on pages 30-31 of the UM1755 BlueNRG Bluetooth LE stack ACI User Manual (linked on the BlueNRG product page).This command has the parameters:where I need to understand the details ofand .However no details are provided.The User Manual says this about these parameters:and in the detailed listing of the command parameters,these two parameters are entirely missing!Can you please provide details for these two parameters:and How many bytes each?If > 1 bytes are they big or little-endian?What are the time units?In other words,if I specify a value of 1 (decimal),what will the corresponding advertising interval be?If this information is available somewhere,please point me to it.Thank you very much! #adv_interval_min #advertising-interval #adv_interval_max #bluehci_gap_set_limited_discoverable

我正在使用安捷伦先进设计系统（ADS-2008）中的微带技术设计Ku-Band中的低噪声放大器/功率放大器/滤波器基板材料主要是RO4003C或RO5880。在低于X波段的频率下，模拟和测量结果之间存在紧密的一致性。但是在X-Band及以上，我总是观察到模拟和测量结果之间的频率变化，这浪费了大量宝贵的资源。最有趣的是，在模拟和测量结果中，性能曲线的形状（S11，S21，S22）几乎保持相同。这种转变有时是积极的，有时是消极的。我总是在微波模式下模拟具有最大可能的网格密度和最小可能的弧分辨率的电路。基板定义如下FreeSpace Substrate //// GND //////金属化层和过孔也正确映射。我怀疑对于某些几何形状，衬底的有效介电常数会发生变化，这会引起偏移，但我也认为ADS2008 Momentum模拟器还应根据仿真过程中的几何和频率计算有效介电常数。因此，不应该观察到这种转变。请帮助这方面，我如何改进模拟以避免频率的这种转变。 以上来自于谷歌翻译 以下为原文I amdesigning Low noise amplifiers/power amplifier/filters in Ku-Band using microstrip technology in Agilent Advanced design system (ADS-2008) Substrate material is mostly RO4003C or RO5880. At frequencies below X-Band, there is close coherence between simulation and measured results. But at X-Band and above, I always observe a frequency shift between simulation and measured results and this wastes lot ofprecious resources. the most interesting thing is that shape of performance curves (S11, S21, S22) remains almost same in both simulation and measured results. this shift is sometimes positive and sometimes negative. I always simulate the circuits with maximum possible mesh density and minimum possible arc resolution in Microwave mode. Substrate is defined as follows FreeSpace Substrate ////GND////// Metallization layers and vias are also correctly mapped. I suspect that for certain geometries, effective dielectric constant of substrate varies and this causes the shift but I also think that ADS2008 Momentum simulator should also calculate the effective Dielectric constant depending on the geometry and frequency during simulation. Thus, this shift should not be observed. Please help in this regard, How I can improve simulation to avoid this shift in frequency.

我正在尝试为PSoC程序员创建一个脚本来编写CY8C4248LQQI-BL43。我需要能够通过调用N.LabVIEW中的一个可执行程序来编程这个部分，这看起来是最简单的选择。我遇到了两个问题：1）命令行接口（CLI）指南中的表1-1指示“程序”功能仅在PSoC 1设备上工作，而对于PSoC4，我看不到类似的命令。也就是说，如果我运行CLI解释器，程序函数就会出现在我的设备上。什么是正确的编程和验证PSoC 4设备的方法？2）在CLI指南的第1.4部分“返回值”中，有一个关于“分析”返回（状态）值的讨论，但是文档中的或以后的示例中没有一个实例描述了如何在脚本中这样做。你应该如何检查返回状态和改变脚本的流程？或者，您应该在每次启动时只执行一个命令来执行CLI解释器，并在DOS批处理文件中处理返回的状态吗？举例说明这是如何实现的，这将有很大帮助。 以上来自于百度翻译 以下为原文I'm trying to create a script for PSoC Programmer to program a CY8C4248LQQI-BL483.I need to be able to program the part by calling an executable from N.I Labview and this looked like the simplest option.I'm running into two issues: 1) Table 1-1 in the Command-Line Interface (CLI) Guide indicates that the "Program" function only works on PSoC 1 devices and I don't see a similar command for PSoC4.That said if I run the CLI interpreter the Program function appears to work on my device.What is the correct method for programming and verifying a PSoC 4 device? 2) In section 1.4 "Return Values" of the CLI Guide there is a discussion about "analyzing" return (status) values but none of the examples there or later in the document actually describe how to do this within a script.How are you supposed to check returned statuses and change the flow of the script?Or are you supposed to execute the CLI interpreter with only one command per launch and process the returned status in a DOS batch file?And example or two showing how this is expected to be accomplished would help greatly.
