Hi Dialog,
我想设计接近应用智慧h DA14585. So for reference, I looked at the smart tag rev. C.
While porting this design, should I make any changes, especially in the antenna region?
We are referring different tags built on 580 and noticed that antenna geometry is same as that of your smart tag reference design, but they have extended little bit. What are the deciding factors for that?
问候，
BLEBOT.

Hi blebot,
对不起，我没有完全得到这个问题，你正在比较的参考设计，你注意到天线几何学有点延长？你能解释一下吗？
Thanks MT_dialog
Hi Dialog,
我正在比较智能标签Rev C天线。为了您的参考，我已经附上了智能标签Rev C的天线部分。文件中的绿色环绕在文件中是我谈论的延伸。那么这会改善范围吗？
Also what is the ideal free space range for the antenna design used in Smart tag rev C. Please share any reference links on the design factors to consider for MIFA antenna type.(If available)
此致，
BLEBOT.
Hi blebot,
I dont think that you can take an antenna design and assume that by increasing the length of the antenna that it will increase also the range, if you would like to make that kind of change the RF enginner will have to properly redesign the antenna and apply the proper matching on the PCB itself and test if this will reach the range that you would like, in general RF design is quite tricky. The Smart Tag with the current antenna should reach about 20 meters in open space (the indication was from some preliminary tests and not a proper range test). You will be able to find antenna guidelines in the AN-B-027: Designing Printed Antennas file.
Thanks MT_dialog
Hi Dialog,
Thanks for the reply. Can you please provide the layout file of smart tag Rev C(.brd file) in lower Cadence version.
Presently our layout engineer is using Cadence 16.5 version and we were unable to open the reference layout file due to version compatibility issue.
Also can you please specify what the PCB thickness should be so that the antenna works perfectly.
Thanks & Regards,
BLEBOT.
Hi blebot,
You will be able to find all the info for the reference design PCB in the DA14580_RD_WLCSP_SMTAG2_vC.pdf file in the Smart Tag v2_revC_HW_DesignFiles file that is uploaded on the support site including the PCB thickness on slide 12. Regarding the .brd files you are looking for they are also in the Design files zip file that is uploaded on the support site.
Thanks MT_dialog
Hi Dialog,
感谢您的答复。我发现了来自支持站点的所有必要的设计文件，包括布局文件（.brd扩展名）。问题是我们的布局工程师无法在Cadence 16.5中打开文件。似乎有版本兼容性问题。
So, please can you do anything regarding this.
问候，
BLEBOT.
Hi blebot,
是的，如果你有16.5，那么你不会能够在HW团队检查以来，你不会能够打开它，让我知道他们正在使用16.6版本，所以我想知道他们是什么意思可以做的是升级Cadence版本。
Thanks MT_dialog
Hi dialog,
We are developing the proximity tag with DA14585, Can u share reference circuit.
In the DA14585 Development board ARM controller is used to communicate with PC, Can i replace the this circuit using the J link emulator.
Thanks & Regards
rekha.
Hi Rekha,
Please refer to the schematic in "5 Hardware Overview" of the attachment.
布罗尔，
Hi dialog,
感谢您对响应并提供输入。如果我想通过J-Link仿真器下载或调试固件到DA14585中，则以下连接是否足够？请建议我。
Pin Numbers
J-Link − DA14585
1 (Vtref) → A7 (Vdd)
7 (TMS) → D1 (SWDIO)
9 (TCK) → C1 (SWCLK)
20（GND）→C3（GND）
Regards
rekha.
Hi Surekha,
Yes, that's right.

Hi dialog,
Can you share the DA14585-00-REXT Evaluation board schematic.
Thanks & Regards
G. Rekha.
Hi surekha,
I am not able to get what you mean with the “REXT”. Could you please clarify where did you get that? Otherwise, please elaborate you request in order to share you the proper documents.
Thanks, PM_Dialog
