Hi
通过简单地在我的原型上更改设备名称，我已经测试了外围示例。（使用iOS应用程序）
and its range is not even 10 meters.
有人可以告诉我这种低范围的原因。
谢谢

Hi paramvir.in,
这个问题非常广泛，我们需要更多信息。，可以在硬件（主要）类似的原因如天线匹配等。
请告诉我们您尝试实施的用例是什么，您使用的硬件是什么，如果您使用过的参考设计以及一些观察结果，则在广告期间或在连接中发生这种情况。，
Also, check this on a Dev Kit and see if there is a range issue.
最好的，

Hi LC_Dialog
现在我刚刚测试了外围示例（在DA14586原型）
//global initialise
system_init（）;
rf_nfm_disable();
with above addition in main function, I checked in user_app_adv_start(void) function if its disabled or not
if（rf_nfm_is_enabled（）））
{
rf_nfm_disable(); // not getting called
}
but still range is same as before less than 10 meters and its for advertising only. looks like I am still missing something.
谢谢
Hi
我用DA14576模块和原型测试了DK Pro上的相同的十六进制文件，范围更为dk。
谢谢。
Hi paramvir.in,
如前所述，可能存在RF设计的问题。请参阅“应用说明”和“用户手册”中指定的硬件设计指南，以验证您的定制板是否符合所有要求。如果一切都在推荐规范中，我们可能必须进行设计审查。如果您希望我们快速查看您的自定义设计，请检查是否存在任何偏差，请告诉我们。
Also, you will need to trim the Crystal and Antenna to improve the RF performance.

Hi paramvir.in,
我注意到，您已使用连接到VDCDC_RF的0.1uf电容而不是我们的AN-B-054中推荐的1UF电容器。将此电容器更改为推荐的值并测试RF性能以进行任何改进。如果RF性能仍然差，请尝试通过移除PI网络并再次测试RFIOP的输出直接向天线。在测试这些后，让我知道您的观察。
最好的，
lc_dialog.
Hi LC_Dialog
I have changed the capacitor value to 1uF and output of RFIOp is directly fed to Antenna.
Result is still the same. very low range compared to DK.
Paramvir
Hi LC_Dialog
我等待着你的回应。
谢谢
Paramvir
嗨paramvir，
检查RFIOP的电源输出以确保问题是否是由于天线或其他内容。将四分之一英寸线直接连接到RFIOP引脚，看看性能是否有提高。确保删除PI网络和芯片天线，同时执行此操作，电线不会环绕，应直接从PCB指向。
It is not recommended to have a GND or metal below the antenna. In your design, there is a battery and battery enclosure right below the chip antenna. This can potentially hinder the RF signal propogation. This can be another reason for reduced performance. Test the reception by removing these components.
Also note that, the chip antennas has lower performance and won't be equal to the Devkit performance.
Can you confirm if you did the antenna matching in your design. This is very vital to get better range.
最好的，
lc_dialog.
Hi LC_Dialog
作为从芯片天线（Johnson）的删除PI网络可能导致功耗或任何其他问题。
谢谢
Paramvir
嗨paramvir，
Apart from the power consumption differences, if the Antenna is not matched properly, you will have unpredictable RF issues. This can arise at any point like during normal testing or at FCC testing etc., You would't want to face such issues in production. It is recommended to match the Antenna or as an alternative, you can also use a Module that is already certified.
最好的，
lc_dialog.
Hi LC_Dialog
we need better range like more than 35 meters can you please suggest possible available antennas for DA14580 (chip or pcb).
谢谢
Paramvir
Hi Paramvir,
I would recommend that you refer to our refernce designs. Some of the designs also contains source files for the PCB Antennas. Also, refer to the Modules developed by our partners to check if any of them fit into your design. These Modules are FCC certified and will eliminate the issues with the Antenna overall.

Hi LC_Dialog
1.将电池从天线移动并移除顶部的电池连接器，单独增加了> = 120英尺的范围。
2. and further on directly feeding the output of RFIOp to chip antenna( removing the pi network components) range increased to > 200 feet.
what is power consumption difference between above two cases, I mean with or without pi network.
now I think I should change the design, but what should be the distance between cell or other metal that should be away from antenna.
以及如何对RFIOP电源的测量以及我需要采取的任何其他测量，请指导如果可能，请告诉我工具和过程。
and if I need to make further bring out pins for measurements in prototype for testing, as I have not done with current prototype.
嗨paramvir，
Regarding the power consumption, there is difference. To get the maximum range, the Antenna has to be matched to input impedence properly. Having said that, the measurements and processes to do that is complex and need RF expertise to execute the design.
我建议您遵循我们的支持网站上提供的参考设计之一。我在这里包括一对可能靠近您的设计。

Hi LC_Dialog
我有一个问题关于骰子的应用程序。做es the dice provide equally well functionality in a moving train (acceleration & deceleration).
because train is always in motion and if there is affect on accelerometer functionality in that case.
谢谢

Hi Paramvir,
Firstly, I think one of the links in the previous post is not accurate, I was referring to our Beacon design but the link refers to DSPS. Here is the accurate link.
https://support.dialog-semiconductor.com/connectivity/reference-designs?qt-view__reference_designs__block_3=0#qt-view__reference_designs__block_3
Coming to you Dice question.,
我们与移动应用程序一起使用的参考应用程序来展示骰子滚动的特定功能。这对加速度计供应商是疑问。以下是我们参考应用程序中加速度计的链接。请访问它们，了解有关此信息的更多信息，请访问它们是否有任何特殊算法或设置以检测常量运动。
