hi Dialog,
Start-up time when DA14581 boot up from SPI flash.
如我们所知，对于电力接收单元（PRU）实现，启动时间是重要参数。
如果我们的A4WP PRU从SPI Flash启动，PRU无法在PTU发送的长标信标（105ms）期间与PTU建立BLE连接。
and there is no problem,when the PRU boot from OTP(start up time is 25ms ).
Any advice for the issue? thanks!
Hello,
We have got SUOTA working exactly as described in AN-B-10 app note and is working very nicely (with default settings and NO security).
I am addressing Security as described in Section 4.1 of the app note and have done exactly as it describes.
I then rebuild fw_1.bin and fw_2.bin with encryption. I have also rebuilt multi_part.bin and programmed successfully. It runs successfully and I am able to run link to it using Smartsnippets. However, when I try to update the image, I get the following error:
I trying to run code from Proximity Tag example on my board. 32K crystall do not fitted on board.
I define CFG_EXT_SLEEP in da14580_config.h file and and set DEVELOPMENT_DEBUG to 0 then burn compiled image in SPI flash.
重置后，我可以看到5个LED闪烁，然后关闭它。当我按下按钮，没有什么是发生的。
I suppose that da14580 goes into extend sleep mode and cant wake up.
If I right, is it possible to change clock source to internal oscillator? What changes I need to do?
Thank you in advance.
Hello.
im kind of new with this bluetooth, im trying to set a pin low when its connected and when its disconnected set it on high, so i want it to do it by asking for the state machine, how can i do that?
this is what i have but is not working.
int state;
int state2;
state=ke_state_get(APP_CONNECTED);
while (state==true)
{
GPIO_ConfigurePin( GPIO_PORT_0, GPIO_PIN_6, OUTPUT, PID_GPIO,true);
GPIO_SetInactive( GPIO_PORT_0, GPIO_PIN_6 );
Hi Everybody,
I'm actually working on a project to communicate two BLE, and I have to modify the soft inside the DA14580. is there some software that i can use to do this? And what are the modification that I need to define a BLE as slave and the other as master?
谢谢你的帮助。
Hi
是否有任何文档可以使用580来启动中央的连接？任何应用笔记/示例代码？
I didn't find any documentation about how to do this, maybe I missed it. It is rather difficult to understand the layout and structure of the documentation
Hi
Is it possible to use a DA14580 as a broadcasting beacon which also acts as a central for multiple peripherals ?
I want the 580 to broadcast advertising data and allow for multiple android phones to connect to it. Since one peripheral can only connect with one central, I am trying to think of a way where the 580 broadcasts data that causes Android devices to connect to it. Is this possible ?
Any suggestions on how to go about this ?
The DA1458x datasheet mentions DMA support in a couple places but does not go into detail. What, if any, DMA support is available on the chip? I would like to be able to offload sending data from a buffer over SPI. The data is for a SPI OLED display and it would simplify my code if I could just have DMA send the data 60 times a second instead of looping through the buffer to fill the SPI FIFO whenever it is empty.
Also, assuming DMA is not available for my purposes, what is the buffer size of the SPI RX and TX FIFO?
Hi
I am trying to get 2 different Android phones to connect to the DA14580.
I am using the "ble_app_barebone template" provided with the SDK. I changed the CFG_MAX_CONNECTIONS parameter to 4 to allow multiple devices to connect.
但是，一旦第一设备连接，其他设备无法看到DA14580（广告停止），另一个设备无法连接到DA14580。
I read that the 580 allows for a maximum of 6 simultaneous connections, can somebody please help me with how to do this ?
Thanks !

Dear Sirs,
我正在SDK5.0.3中为灯架创建一个农场。
I have designed the FW to change the part of the advertising data every few seconds.
弗兰克-威廉姆斯将一段时间操作,但弗兰克-威廉姆斯将停止the advertising.
I dont want that advertised stops.
当FW停止广告时，在User_PeripherAl.cn的User_App_Adv_Undirect_Complete（）中，它已接收了一个GAP_ERR_NO_ERROR或GAP_ERR_COMMAND_DISALLED作为状态。
(Normally, it has received a GAP_ERR_CANCELED.)
