你好
I have tested the peripheral example, by simply changing the device name, on my prototype. (using iOS app)
它的范围甚至不是10米。
can someone please tell me the reasons for such low range.
Thanks

嗨paramvir.in，
The question is very wide and we need more information here., there can be mulitple reasons in hardware (mostly) like the antenna matching etc.,
Please let us know what is the use case that you are trying to implement, what is the hardware you are using like, if there is a reference design that you have used and some observations like, is this happening during advertising or when in connections etc.,
此外，请在DEV套件上查看此功能，看看是否存在范围问题。

嗨lc_dialog.
for now I have just tested peripheral example with (on da14586 prototype)
//全球初始化
system_init();
rf_nfm_disable（）;
随着主要功能的上方，如果其禁用或不禁用，则在user_app_adv_start（void）函数中检查
if(rf_nfm_is_enabled())
{
rf_nfm_disable（）;//没有被称为
}
但仍然范围与不到10米之前的范围，仅供广告。看起来我仍然错过了一些东西。
Thanks
你好
I have tested same hex file on DK pro with DA14576 module and prototype, range is much more DK.
Thanks.
嗨paramvir.in，
As informed before, there might be an issue with the RF design. Please refer to our Hardware design guidelines specified in the App Notes and User Manuals to verify that your custom board is meeting all the requirements. If everything is with in the recommended specifications, then we might have to do a design review. If you would like us to do a quick review of your custom design to check if there is any deviation from the recommendations, let us know.
此外，您需要修剪晶体和天线以提高RF性能。

嗨paramvir.in，
I have noticed that you have used a 0.1uF capacitor connected to the VDCDC_RF instead of a 1uF capacitor recommended in our AN-B-054. Change this capacitor to the recommended value and test the RF performance for any improvement. If the RF performance is still poor, try and feed the output of the RFIOp directly to the Antenna by removing the pi network and test again. Let me know your observations after testing these.
Best,
LC_Dialog
嗨lc_dialog.
我已将电容值更改为1UF，RFIOP的输出直接送入天线。
结果仍然是一样的。与DK相比非常低。
Paramvir.
嗨lc_dialog.
I am waiting for your response.
Thanks
Paramvir.
你好paramvir,
Check the power output from the RFIOp to make sure if the issue is due to the antenna or something else. Connect a quarter of an inch wire directly to the RFIOp pin and see if there is an improvement in the performance. Make sure you remove the PI network and the chip antenna while doing this and the wire is not coiled around, should be pointed straight away from the pcb.
建议不要在天线下方具有GND或金属。在您的设计中，芯片天线以下有电池和电池机箱。这可能会阻碍RF信号偏移。这可能是降低性能的另一个原因。通过删除这些组件来测试接收。
另请注意，芯片天线具有较低的性能，并且不会等于Devkit性能。
你能否确认你是否在设计中匹配的天线。这对获得更好的范围非常重要。

LC_Dialog
嗨lc_dialog.
As the removing pi network from chip antenna (Johnson) can cause power consumption or any other issue.
Thanks
Paramvir.
你好paramvir,
除了功耗差异，如果天线不正确匹配，您将有不可预测的RF问题。这可以在正常测试期间或在FCC测试中出现，您可能希望面临生产中的此类问题。建议使用天线或替代方案，您还可以使用已认证的模块。

LC_Dialog
嗨lc_dialog.
我们需要更好的范围，如超过35米，您可以提示DA14580（芯片或PCB）的可用天线。
Thanks
Paramvir.
嗨Paramvir，
我建议您参考我们的推荐设计。部分设计还包含PCB天线的源文件。此外，请参阅我们的合作伙伴开发的模块，以检查其中的任何一个是否适合您的设计。这些模块是FCC认证，并将消除整体天线的问题。

1. moving the cell away from the antenna and removing the battery connector on top has increased the range to >= 120 feet alone.
2.此外，在直接馈送RFIOP输出到芯片天线（移除PI网络组件）范围增加到> 200英尺。
什么是2个案例之间的功耗差异，我的意思是或没有PI网络。
现在我觉得我应该改变设计，但是应该有什么应该远离天线的单元格或其他金属之间的距离。
and how do I take measurements for RFIOp power and any other measurements I need to take, please guide if possible let me know the tools and process.
如果我需要进一步开展针对原型进行测量的引脚，因为我没有使用当前原型。
你好paramvir,
关于功耗，存在差异。为了获得最大范围，必须正确匹配天线以正确输入阻碍。已经说过，测量和流程是复杂的并且需要RF专业知识来执行设计。
I would recommend you to follow one of our reference designs provided on our support website. I am including a couple here that might be close to your design.

嗨lc_dialog.
我有一个关于骰子申请的问题。骰子是否在移动的火车（加速和减速）中提供同样井的功能。
因为火车总是在运动中，如果在这种情况下有影响加速度计功能。
Thanks

嗨Paramvir，
首先，我认为前一篇文章中的一个链接不准确，我指的是我们的信标设计，但链接是指DSP。这是准确的链接。
https://support.dialog-seminile.com/connectivity/reference-designs?qt-view_reference_designs__block_3=0#qt-view_reference_designs__block_3.
来找你骰子问题。，
The refernce application we have works with our mobile application to demonstrate the specific functionality of the dice rolling. This would be question to the accelerometer vendor. Here is a link to the accelerometer in our reference application. Please approach them for more information on this to find out if they have any special algorithms or settings to detect constant motion.
