大家好。
I want to develop a Beacon.
所以，我有Quesetions：
有最新的灯塔开发项目吗？
What Reference data for Guide to Develop？
Is need Special APK in Android system and Special Application in IOS system for test?
谢谢 。

嗨袁汉吴，
No there isn't a new iBeacon project, you can use the existing Beacon reference design in order to develop the project you want, for beacon's there are application in Google Play store that pasrse different formats of Beacons as iBeacon, Altbeacon etc.....for example Locate is one of them that supports many beacon formats.
谢谢MT_dialog
大家好。
Ah,iBeacon there is a Standard Agreement? The existing Beacon project can used directly for Satisfied custom claim?
I haved view Beacon project. In it is nothing profile used,so I am not start.
请给我帮助。
谢谢。
Hi YuanhangWu,
Sorry, i didn't get your problem, can you please rephrase?
The phone app you are using can't detect the beacon project?
谢谢MT_dialog
The existing Beacon project is standard,so,I can used the existing Beacon project directly.Right?
But i used a Beacon APP download from android Market，it is not work with the project.
I view Beacon project,but I see there is no profile that to be used in the project.
为什么？
灯架有任何文件？
Application in IOS system also not work.
该应用程序找不到该项目。也许是因为app_scnrsp_data不对。
APP_SCNRSP_DATA how to set it?
谢谢
Hi YuanhangWu,
信标只是广告字符串，他们不使用任何配置文件，这就是为什么找一个。应用程序找不到信标的原因是因为CompanyID字段被列为与应该的标识符不同的标识符。雷电竞下载app您可以在UM-B-019中找到有关Beacon应用程序的更多信息。
谢谢MT_dialog
Hi all.
UART SPS
CPU <------------------------------------------>DA14580<------------------------------------------------------>PHONE
(1)
IIC SPS.
CPU <------------------------------------------>DA14580<------------------------------------------------------>PHONE
(2)
在SPS项目中使用UART连接到CPU为（1）。
But in my project the uart have been used.
So I want to used the IIC to replace UART for SPS project.
iic是可以用这样的吗？
数据来自CPU时如何播放DA14580？
Is there any document for this project develop?
谢谢。
Hi all.
I have an overview the existing Beacon project,I understood the beacon is a advertising only.
But the existing Beacon project's advertising data is Constant.
I have a question:
灯塔advertising same data Constantly?
信标项目的广告数据不会因要求而改变？
thanks
Hi YuanhangWu,
Yes you can change the advertising data either from the SPI or from the custom service when the device becomes connectable by using the button. When you connect to the beacon you can use the extra characteristics of the custom service to change the uuid, major, minor, companyid, advertising interval, tx power as document indicates.
谢谢MT_dialog
Thank you MT_dialog.
I have a other question:
Taking into account the real needs,is a SPI EEPROM Memory need for SPOTAR in beacon project?
谢谢。
Hi YuanhangWu,
Yes if you want to use the SPOTAR module you need an SPI flash in order to store the second image.
谢谢MT_dialog
Hi all.
use DA14580_BEACON_3.40.6 project,only changed Advertising data.
14580 40pin chip,Minimum System,with no 32.768k crystal oscillator.
Can find by phone.
I have question is:
The current consumption is 100ua average?
How to reduce the current consumption?
谢谢。
Hi YuanhangWu,
You can find all the available current measurements in the Beacon documentation. You can reduce the power consumption by setting longer advertising intervals.
谢谢MT_dialog
Hi MT_dialog,
Setting longer advertising intervals to 700 ms ,
test it is 20 ua average.
有没有办法降低功耗？
谢谢。
Hi all,
I have two more detail question:
UM-B-019 document write this:
\xc5: Measured power at 1 m: -59 dBm,
如果我写0 xba字节,
can this handler be legal?
And write 0XBA for this byte will enhance power consumption?
Transmitted power amplifier can be adjust?
Where is the code to adjust it?
With no 32.768k crystal,
the RCX20 is more power consumption than 32.768K when sleep?
The RST pin is connect a resistance to GND.
这是正确的吗？
In da14580 datasheet,RST is suspend.
Have more handle to reduce the power consumption?
谢谢。
Hi YuanhangWu,
What kind of sleep are you using deep or extended, deep is less power consuming but it requires the OTP. The \xc5 value is just a static value that informs the android application about the output power of the beacon in 1m. With that value the android application can calculate the distance of the device. The RCX20 is not more power consuming by the XTAL, dialog recomends that the unused pins to be left as floating but i suppose that you are ok with the reset pin to the ground and it wont cause you any trouble. Also you can reduce the transmited power by using Near Field Mode (check the datasheet page 153, Note 25 for further information). You can enable the near field mode by defining NEAR_FIELD_MODE_ENABLED.
