Hi Dialog Team,
我正在使用SDK文件夹中的“BLE_APP_NONCONN”示例的自定义板。我的项目要求如下。
- Go to sleep mode (ARCH_EXT_SLEEP_ON) whenever no ble or other activity.
- 当外部传感器提供数据时,对话框芯片将唤醒引脚更改中断并使用计时器0开始从传感器中解码数据。
- Decode the data and update it on the advertisement string.
- 使用'user_app_adv_start()'启动广告,并启动一个易于计时器,将在6秒内过期。直到那时广告数据被宣传。当App_easy Timer到期时,使用'app_easy_gap_advertise_stop()'停止广告,这将使芯片睡眠。
- Before stopping advertisement, the wakeup pin will be enabled to wake up the chip from sleep when the next data is ready.
I have mananged to complete the above steps in debugging mode. When I run my program on the RAM and disconnect the debugger the current consumption reduces to 2.4µA. When the external interrupt occurs the current rises to around 50µA and oscillates between 2.4µA to 50µA. ( I guess this is due to the sleep between advertising internvals). So I think the above concept works fine.
But I am stuck at two problems.
1) During sleep mode ( debugger disconnected condition ) when my chip advertises I think it advertises only once. Because I am checking it on a BLE scanner app and I notice that the RSSI value is updated only once. It it only transmitiing once?. If it is transmitting once, then why the current oscillation between 2.4µA to 50µA for the 6 sec duration?
2) The above condition works for a while and all of a sudden, the current increases to 350µA and then there is no advertisement at all. Is my program halted?
Please note that the above two condition occurs only when I disconnect the debugger.
What could cause these two issues during sleep?
问候,
Mark


嗨马克,
When performing any kind of measurements in sleep mode, you should not run the firmware in debug mode. Otherwise, the device fails to go into sleep mode and the power consumption will be dramatically increased. To do so, my suggestion would be to have the debugger de-attached, as this prevents the system to sleep. Additionally, a very important tip is that in case you are using SPI Flash in your custom board, you should power it down.
你可以尝试再试一次吗?请在调试模式下运行它 - 在此步骤中的功耗并不重要。你提到的是广告一次......在第一个广告之后,FW是什么?WDOG已启用或禁用?我建议您启用它,否则如果FW粘在某个地方,您将不会收到通知。如果您完全确定FW按预期运行(未发生WDOG或NMI),请使用SmartSnippets Toolbox的电源分布程序检查它是否未广告一次。
谢谢,PM_Dialog
嗨pm_dialog,
When running in debug mode, the code advertises properly and the firmware does not get stuck anywhere. I ran the code in debug mode for more than an hour and it works fine. When I disconnect the debugger and run it, the problem ( as mentioned in the first post) occurs.
我确实有别的疑问。您的示例代码在“MISC”文件夹中的“BLE_APP_NONCONN”是否支持扩展睡眠模式?因为在调试模式下连接时它正常工作。但是当我断开调试器时,问题就开始了。
我是广告6秒钟并停止它。但它仅广告一次,但整个6秒内的当前消耗量有振荡。这意味着它在广告间隔之间唤醒,但为什么不发送数据包。?
问候,
Mark
嗨马克,
The ble_app_nonconn project of the SDK6.0.12 does not support sleep mode by default. However, you can change the sleep mode configuration. Since it’s a custom code and custom board, would it be possible to share the changes you have done in order to configure it in sleep mode? Another option to start investigating which is the route cause might be to start toggling a GPIO or printing some debugging messages, as the firmware gests stuck only in non-debug mode. In debug mode, I assume that you have the WDOG enabled..
谢谢,PM_Dialog
Hi PM_Dialog,
我的固件不会被卡住。它仅在整个6秒持续时间传输单个广告。但是在调试模式下,它会在6秒持续时间传输4到5次。为什么它只在非调试模式中传输一次?是影响BLE广告的睡眠模式吗?
对于睡眠模式,我已经进行了以下更改。
6秒后,我停止了广告,我的芯片进入延长睡眠。
问候,
Mark
嗨马克,
Not sure what happen since it is a custom board/code. Can you please use the arch_printf() in the user_app_adv_start() and in the user_app_adv_nonconn_complete()? Also, can you please send me a screenshot from the Power Profiler? When the debugger is attached and de-attached.
谢谢,PM_Dialog
Hi ,
我没有选择在我的自定义板中打印邮件。我正在使用万用表来测量当前消耗。
我认为问题在于调用user_app_adv_start() function when i am ready to advertise again.
I have attached the code below for your refernce.
Hi PM_Dialog,
As u suggested, i pulled down a GPIO onperiph_init()and pulled it high before going to sleep beforearch_goto_sleep(sleep_mode)in arch_main.c. I attached the screenshot of oscilloscope output. The problem I am facing is, when I call user_app_adv_start(), the chip is transmitting the data only once. I confirmed this by looking at the RSSI value on the BLE scanner app in android. I have attached the sample code also.
正如我对我的产品的紧急演示一样,我已经改变了广告间隔到200ms和以某种方式通过调用'user_app_adv_start()'和1秒后我停止它以及在我打电话的广告完整功能之后宣传数据。user_app_adv_start()'再次。我在我的应用中重复了6秒钟,我正在获得多面广告命中。每次我打电话'user_app_adv_start()',我在我的应用程序中只有1个点击,直到我停止广告并再次调用它。
Why does 'user_app_adv_start()' advertising the data only once?
你能请分享我一个信标dat的示例代码吗a which wakes up on an external interrupt and modifies the advertising string and transmits it and goes to sleep.
问候,
Mark
嗨马克,
Let me check it and I'll get back to you.
谢谢,PM_Dialog
嗨马克,
The arch_main.c is SDK file and it is highly recommend NOT modifying any SDK file. All the modifications should be done in the application layer, in the filed that start with user_ . All the other files as SDK related and if any of them is modified we cannot guarantee that the application will work correctly. The SDK should be used as it is provided by dialog without any other modification.
Regarding you source code I am not able to compile it as I am getting couple of errors. Please see below a diff file for how to stop non-connectable advertising, put the device in sleep mode and wake it up. My recommendation would be to start with ble_app_sleepmode example of the SDK which contains advertising data update as well. How you would like to build the application and how to update the beacon data is up to you. Please follow the steps in the ble_app_sleepmode example of the SDK.
谢谢,PM_Dialog
Hi PM_Dialog,
1)你编译我的代码时,你得到了什么样的错误?
2) I modified your arch_main.c file because, when my sensor sends an interrupt I have to wait around 20ms for getting the data, but if I dont wait my code will go back into sleep and I will miss the data. That's why I modified the arch_main.c file to wait till I get the data out and then put the chip to sleep. How to prolong the wake time of the chip?. Can you suggest an idea for that?.
3)当我开始我的广告时,我添加到Arch_main.c的大多数代码内容都不会执行,因为我正在检查主循环中的条件,我不会在我广告时执行它。为什么会影响你的SDK和广告序列?
4)当我收到中断时,直到我从传感器处理数据时,我就不会启动广告。在我收到数据后,我将开始广告,我相信我的代码都不会在广告期间运行。那么为什么这对SDK给出了任何问题?
谢谢,
Mark
Hi PM_Dialog,
Please support me on the above points. As you suggested I have started working on the sleepmode project in ble_examples. My biggest doubt is when my external sensor gives an interrupt and gives the data only after 20ms, how do I have to prevent the chip from going into sleep for that 20ms after I had woken up from sleep.
问候,
Mark
嗨马克,
请使用Keil IDE中的错误查找日志文件。指示您正在使用的SDK版本是非常有帮助的。不确定SDK版本,但我们强烈建议使用最新版本(SDK6.0.12)。
谢谢,PM_Dialog
Hi PM_Dialog,
在添加外部32kHz晶体振荡器后,该问题被整理出来。
It seems that that the ble_app_sleepmode code is unstable without the 32Khz crystal. But your datasheets say that this 32Khz is optional which is very much misleading. Please correct the datasheets or it may mislead others too. I have spent 3-4 months on this issue and had no clue it was due to the external crystal.
任何方式,谢谢你的在线支持。
问候,
Mark
嗨马克,
很高兴你有工作。这是对我们之前的会议呼叫讨论的内容。谢谢你的迹象。
