Hi,
We would like to know how to enable BT HCI over UART mode of DA14585. Are there any settings that need to be done ? We want to send the BT HCI command over UART directly to BLE controller and get back the response back. We want to use another Bluetooth stack and communicate with chip directly.
Thanks,
Rahul

嗨rahult，
In order for the 585 to operate under HCI mode, you will have to download the appropriate fw, you will be able to find the fw in the SDK 6.0.4 in the following directory DA14585_SDK\6.0.4.326\projects\target_apps\hci, then you will have to provide the RX/TX/RTS/CTS connections with the corresponding pins (that depends on the device you are using) and you will be able to send UART HCI commands directly to the 585 and get back the appropriate response.
谢谢mt_dialog.
嗨mt_dialog，
Tried building the 'DA14585_SDK\6.0.4.326\projects\target_apps\hci' project and executed in the Debug Mode with selected target hci_585, but seeing the Hardfault. Tried finding out the issue, but couldn't root cause it. Kindly do the
细节：
1. DA14585_SDK -6.0.4.326
2. DA14585 DEV KIT PRO
3. j5配置为UART，J10已启用，J3已打开。
4. SDK配置文件无需下载SDK的更改。

Kindly let us know any configurations required to use DA14585 as BT HCI UART mode.

嗨nitish，
我刚刚重复你的步骤，只要我使用DA14585的大规模生产版本就没有问题。试图用修订版AB Silicon重复，我得到了完全相同的硬盘。
如果字母AB是SOC上的修订号标记的一部分（芯片标识符DA14585下面），则您有必须更换的早期硬件。有关如何安排更换的详细信息，请联系您当地的销售代表。MP硬件上的修订号是所有零。

Hello MHv,
附加DA14585的图像，以及我们看到的修订号如下。不要以为它的ab硅。请告诉我们我们可以做些什么来实现这项工作。
如果你可以帮助我们尽快享受。
DA14585-01ATDB-P（1711_00015）。
Thanks,
Nitish
谢谢你提供图片。您的女儿卡似乎是早期的工程样本。请询问您的对话经销商或代表换货替换。

谢谢mhv，
我们采购了新硅，现在我们没有看到硬断层。但看到一些其他问题。
1.构建项目da14585_sdk \ 6.0.4.326 \ projects \ target_apps \ hci 585，启动了调试会话并开始执行代码（F5）。我现在认为固件下载到SRAM（通过UART1 P0_4UTX，P0_5URX，P0_5CUCTS，P0_7urts）并开始执行。现在停止了调试会话（使用UART1）。
2.但现在我们预计UART1将用于BT HCI接口（BT主机和Dialog585 BT控制器）。因此，在J5中删除了跳线，将UART P0_4-P0_7与USB通信引脚连接。并通过UART接口运行BT主机的控制器连接UART P0_4-P0_7。并看看没有适当的沟通。
3. When i monitored the standalone Dialog585 P0_4 & P0_5 pins post downloading and running the HCI firmware, through picoscope, see some random unexpected signals (attached the images).
笔记：
1. BT主机设置随着UART HCI接口的其他BT控制器运行精细。
2.主机和对话框UART设置都很好。配置了115K2波特，无奇偶校验，并尝试了启用和禁用HW流量控制。
请告诉我们是否使用其他设置/ UART配置以使其工作。
Thanks,
Nitish
嗨nitish，
我相信拆下跳线并连接到BT主机的程序可以触发DA14585复位。你可以尝试在开头和bt主机连接uart重复步骤1？JTAG（SWDIO和SWCLK）用于将代码下载到SRAM中，但在KEIL中。
Thanks MH_Dialog,
I tried the following steps, but see there is no response/activity from the P0_5 [uRx] pin or other UART pins(P0_4, P0_6 or P0_7) of the DA14585.
脚步：
1.使用Keil为585构建项目DA14585_SDK \ 6.0.4.326 \ Projects \ Target_Apps \ HCI。
2.现在使用“选择DA14585选项的JTAG配置”使用SmartSnippets工具箱，打开设备并选择“Booter”工具。
- 使用da14585 \ da14585_sdk \ 6.0.4.326 \ projects \ target_apps \ hci \ hci \ keil_5 \ out_585 \ hci_585.hex二进制使用keil生成的。
- Options was kept as it is. SysCtrlReg=0xA6 for 585
- 尝试使用启用和禁用“关闭调试会话”。
3.下载FW的发布成功。现在，不要看到UART端口P0_4-P0_7中的随机信号，但我也不看出任何响应（通过Pycope监视P0_4 UTX通过PicoSce）从主机发送的HCI RESET命令。
善意。
Thanks,
Nitish

嗨nitish，
没有响应DA14585的可能原因。
1. Is there a XTAL 32K on the board ? if not, please define CFG_LP_CLK as LP_CLK_RCX20 because LP_CLK is used to wake up the chip.
2.如果您有xtal 32k，请禁用睡眠模式以查看是否有任何响应。更改app_default_sleep_mode = arch_sleep_off;
3.如果步骤2工作，请恢复睡眠模式并定义CFG_EXTERNAL_WAKEUP
如果这些建议提出解决问题，请告诉我
Thanks MH_Dialog,
通过禁用睡眠模式，UART通信工作正常。请在内联的评论中找到。
1. Is there a XTAL 32K on the board ? if not, please define CFG_LP_CLK as LP_CLK_RCX20 because LP_CLK is used to wake up the chip.
- [Nitish]根据DA14580 Dev Kit Pro文件，该DEV板对XTAL32K提供了支持。我通过将断点检查为XTAL32K来检查它来验证它。
在文件中：ARCH_SYSTEM.C，INIT_PWR_AND_CLK_BLE（）
setbits16（sys_ctrl_reg，clk32_source，1）;//选择xtal32k作为LP时钟
2.如果您有xtal 32k，请禁用睡眠模式以查看是否有任何响应。更改app_default_sleep_mode = arch_sleep_off;
- [nitish]是的，现在DA585正在响应主机BT HCI命令。
3.如果步骤2工作，请恢复睡眠模式并定义CFG_EXTERNAL_WAKEUP
- [Nitish] Now even in sleep mode its working fine by enabling the external wakeup. But see following observation or performance issue.
使用app_default_sleep_mode = arch_sleep_off;BT init发生在秒内。
With app_default_sleep_mode = ARCH_SLEEP_ON && CFG_EXTERNAL_WAKEUP enabled, See that BT init takes 4-5 seconds. Not sure why DA585 is taking so much time to respond.
请告诉我们，如果可以解决任何事情以解决DA585可以解决此问题。
问候，
Nitish.
嗨nitish w，
我已经测试了HCI弗兰克-威廉姆斯(取决于反对figuration that you have regarding the flow control, no flow control/with flow control), as far as i can tell you dont need to define the CFG_EXTERNAL_WAKEUP unless you use an additional pin for waking up the device. Check that the HW_CONFIG is set to work with the pro dk and not and make sure that the terminal that you are issuing the HCI commands has the RTS/CTS flow control enabled. Tested on my side with the pro kit, the responses for the commands for getting the bd address and the reset command are proper and i dont see any delays between the command and the response. Also since the device is only working with the sleep deactivated i can assume that something is wrong with the flow control, so please make sure that you have enabled it from the terminal that you send the HCI commands.
谢谢mt_dialog.
嗨支持团队，
首先，我无法在网站上发布新询问。
其次，我在使用DA14585上使用BT固件中的错误。
Issue: BLE Advertising Enable Command Fails post BLE Scanning is enabled(as per the BT spec, both adv & le scan can go simultaneously(by time sharing)).
脚步：
1.使用Keil为585构建项目DA14585_SDK \ 6.0.4.326 \ Projects \ Target_Apps \ HCI。(Tried disabling and enabling Sleep mode app_default_sleep_mode)
2.现在使用“选择DA14585选项的JTAG配置”使用SmartSnippets工具箱，打开设备并选择“Booter”工具。
- 使用da14585 \ da14585_sdk \ 6.0.4.326 \ projects \ target_apps \ hci \ hci \ keil_5 \ out_585 \ hci_585.hex二进制使用keil生成的。
3.下载FW的发布成功。
4. Run my host stack over the DA585, then host app does the ble scan enable and then followed by ble advertising enable. But the advertising enable hci command(0x200a) fails with status 'cmd disallowed 0x0C'.

但是当执行相同的adv启用命令而不发出ble scan enable命令时，它会成功。我认为这是问题的根本原因。请确认此问题并为我们分享此问题的修复。
笔记：
1.和相同的主机应用程序和堆栈在不同的BLE控制器上运行。并且已发布的命令是BT 5.0规范符合标准。
2.将HCI命令和事件附加到/从控制器发送，以供参考。
Thanks,

嗨nitish w，
关于您无法发布新问题的事实，请在支持论坛上打开三个主要类别之一，应该有一个黑色按钮，表示“新主题”您是否能够看到。
关于您的第二个问题，585的BLE堆栈不支持扫描和广告同时，当您连接时，您可以同时扫描或宣传但不同时宣传和扫描。所以在开始新的广告或扫描之前，您是否停止扫描或广告？
谢谢mt_dialog.
