使用BT HCI对DA14585的UART

你好,

我们想知道如何通过DA14585的UART模式启用BT HCI。是否有任何需要完成的设置?我们要将BT HCI命令直接发送给UART到BLE控制器并返回响应。我们希望使用另一个蓝牙堆栈并直接与芯片通信。

谢谢,
拉胡湖

Hi rahult,

Hi rahult,

为了使585在HCI模式下运行,您必须下载相应的FW,您将能够在以下目录DA14585_SDK \ 6.0.4.326 \ Projects \ target_apps \ hci中找到sdk 6.0.4中的fw。然后,您必须提供与相应引脚的Rx / Tx / RTS / CTS连接(这取决于您使用的设备),您将能够将UART HCI命令直接发送到585并返回适当的响应。

Thanks MT_dialog

Hi MT_dialog,

Hi MT_dialog,

尝试构建'da14585_sdk \ 6.0.4.326 \ projects \ target_apps \ hci'项目,并使用选定的目标hci_585在调试模式下执行,但看到硬盘。试图找出这个问题,但不能root原因导致它。请做
Details:
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。

调试细节:
崩溃在:memcpy(hci_cmd_desc_root_tab,rom_hci_cmd_desc_root_tab,48);在Arch_rom.c.中
R14(LR): 0xFFFFFFF9,
MSP: 0x07FC35F8 - whose PC: 0x07F1E0AC

请告诉我们使用DA14585作为BT HCI UART模式所需的任何配置。

谢谢,

Hi Nitish,

Hi 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。

If the letters AB are part of the revision number marking on the SoC (underneath the chip identifier DA14585), you have early hardware that must be replaced. Please contact your local sales rep for details on how to arrange replacement. The revision number on MP hardware is all zeroes.

你好MHV,

你好MHV,

Attaching the images of the DA14585, and the revision number that we see is as below. Don't think its AB silicon. Kindly let us know what else we can do to get this working.
Would appreciate if you could help us out asap.
DA14585-01ATDB-P (1711_00015).

谢谢,

谢谢mhv,

谢谢mhv,
We procured the new silicon, and now we don't see the hard fault. But see some other issue.

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.当我监视独立对话框585 P0_4和P0_5引脚下载并运行HCI固件,通过PicoSce,请参阅一些随机意外的信号(附加图像)。
Note:
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。

谢谢,

Hi Nitish,

Hi Nitish,

I believe that the procedure to remove the jumper and connect to BT host can trigger the DA14585 a reset. Can you try to connect the UART with BT host in the beginning andrepeat step 1? JTAG (SWDIO and SWCLK) is used to download the code into SRAM, but UART in Keil.

谢谢mh_dialog,

谢谢mh_dialog,

我尝试了以下步骤,但请参阅DA14585的P0_5 [URX]引脚或其他UART引脚(P0_4,P0_6或P0_7)没有响应/活动。

Steps:
1.使用Keil为585构建项目DA14585_SDK \ 6.0.4.326 \ Projects \ Target_Apps \ HCI。
2. Now using SmartSnippets Toolbox with Jtag configuration for Da14585 option selected, opened the device and selected the 'Booter' tool.
- Used the DA14585\DA14585_SDK\6.0.4.326\projects\target_apps\hci\hci\Keil_5\out_585\hci_585.hex binary that is generated using keil.
- 根据它的选择保留。sysctrlreg = 0xa6 585
- Tried using both enabling and disabling 'close debug session'.
3.下载FW的发布成功。Now don't see the random signals in UART port P0_4-P0_7 but neither do i see any response(monitoring the P0_4 uTx through Picoscope) for the HCI reset command that is sent from the host.

善意。

谢谢,

Hi Nitish,

Hi Nitish,

There are few possible reasons that no reponse from DA14585.

1.电路板上有XTAL 32K吗?如果没有,请将CFG_LP_CLK定义为LP_CLK_RCX20,因为LP_CLK用于唤醒芯片。

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. if step 2 works, please restore the sleep mode and define CFG_EXTERNAL_WAKEUP

如果这些建议提出解决问题,请告诉我

谢谢mh_dialog,

谢谢mh_dialog,
By disabling the sleep mode, UART communication works fine. Please find inline comments.

1.电路板上有XTAL 32K吗?如果没有,请将CFG_LP_CLK定义为LP_CLK_RCX20,因为LP_CLK用于唤醒芯片。
- [Nitish] As per the DA14580 Dev kit Pro document, this dev board has support for XTAL32K. I verified it by putting breakpoint to check the LP clock is set to XTAL32K.

在文件中:ARCH_SYSTEM.C,INIT_PWR_AND_CLK_BLE()
SetBits16(SYS_CTRL_REG, CLK32_SOURCE, 1); // Select XTAL32K as LP clock

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] Yes, now Da585 is responding to Host BT Hci commands.

3. if step 2 works, please restore the sleep mode and define CFG_EXTERNAL_WAKEUP
- [nitish]现在即使在睡眠模式下,它通过启用外部唤醒而工作正常。但看到以下观察或绩效问题。
使用app_default_sleep_mode = arch_sleep_off;BT init发生在秒内。
使用app_default_sleep_mode = arch_sleep_on && cfg_external_wakeup启用,请参阅bt init需要4-5秒。不确定为什么DA585正在花这么多时间来回应。
Kindly let us know, if anything could be done to resolve this performance issue with DA585 could be resolved.

问候,
nitish。

嗨nitish w,

嗨nitish w,

我测试了HCI FW(取决于您对流量控制的配置,没有流量控制/有流量控制),只要我可以告诉您不需要定义CFG_EXTERNAL_WAKEUP,除非您使用额外的PIN唤醒设备。检查HW_Config是否设置为使用PRO DK,而不是并确保您发出的终端发出HCI命令具有启用RTS / CTS流量控制。使用Pro套件在我的身边测试,对获取BD地址的命令和reset命令的命令响应是正确的,我不会在命令和响应之间看到任何延迟。此外,由于设备仅与睡眠失效,因此我可以假设流量控制有问题,因此请确保您已从您发送HCI命令的终端启用它。

Thanks MT_dialog

Hi Support Team,

Hi Support Team,

Firstly, Am unable to post new queries on the website.
其次,我在使用DA14585上使用BT固件中的错误。

问题:BLE广告enable命令失败后BLE扫描已启用(根据BT规范,ADV&LE SCAN都可以同时进行(按时间分享))。
Steps:
1.使用Keil为585构建项目DA14585_SDK \ 6.0.4.326 \ Projects \ Target_Apps \ HCI。(尝试禁用和启用睡眠模式app_default_sleep_mode)
2. Now using SmartSnippets Toolbox with Jtag configuration for Da14585 option selected, opened the device and selected the 'Booter' tool.
- Used the DA14585\DA14585_SDK\6.0.4.326\projects\target_apps\hci\hci\Keil_5\out_585\hci_585.hex binary that is generated using keil.
3.下载FW的发布成功。
4.在DA585上运行主堆栈,然后主机应用程序执行BLE扫描启用,然后是BLE广告启用。但是,广告启用HCI命令(0x200A)失败,状态'CMD不允许0x0C'失败。
Logs::
nitish :: prepaser_cmd:opcode = 0x2008

prepace_cmd:params [0] = 0x40

cc_evt:opcode = 0x2006,status = 0x00

CC_evt: opcode=0x200a, status=0x0c

5. But when the same adv enable command is executed without issuing the BLE scan enable command then it succeeds. I think this is the root cause of the issue. Kindly confirm the issue and share us the fix for this issue.

Note:
1. And the same host app and stack runs on different ble controller fine. And the issued commands are BT 5.0 spec compliant.
2.将HCI命令和事件附加到/从控制器发送,以供参考。

谢谢,

嗨nitish w,

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。

Regarding your second question, the BLE stack of the 585 doesn't support scan and advertising at the same time, when you are connected you can scan or advertise but not advertise and scan simultaneously. So have you stopped the scanning or the advertising before starting the new advertising or scanning accordingly ?

Thanks MT_dialog
