I've had lot of trouble getting an answer for this question and exhausted my resources so I came to the forum. I apologize as this is not a technical question and more of a sales question:
Can the DA9062 be purchased preloaded with a configuration file provided by the consumer?
如果是这样，订购信息是什么？
谢谢，
Andy
Hello,
I'm currently using the DA1458 and I have modified the user_sensor_reports.h to add an extra data field (uint32_t, currTime) to get the current time value from HW. And I'm calling lld_evt_time_get() on user_sensor_reports.c as follows:
I debug the DSPS example(v5.150.2), and can only send from PC to DSPS app, when send from app, the user_ble_push function get called, but seems can not trigger any send from UART TX. I'm using custom board, and my board use P0.4 as TX and P0.5 as RX. If I download and debug the ancs project, it can print message to PC, and the ancs project also use P0.4 as uart tx, so the hardware of my custom board is OK.
For the buck working mode, we find the Figure 69: Lithium Coin Cell Powered System Diagram (Buck Mode) in datasheet page219.
For the circuit, I have a euqation that why we need to use an inductor L1 at swich pin. Because I think with the decoupling capacitor, we already can remove the high frequency noise
Check out the app note below to learn how enabling and disabling the RC OSC current source to always be turned on in the SLG46140 chip affects the delay block functionality:
Hi,
我使用DA 14861可穿戴,我会的like to ask if i can use the power profiler, because when i connect the CIB with the wearable and according to the tutorial when you press the SmartSnippets Toolbox and configure the first step (JTAG option, settings etc) when i go to the power profiler i cannot press the initialize button thus i cannot see the statistics. By the way, when i press the SmartSnippets Toolbox it show an error message "SDK configuration xml file could not be found. Using bundled support packs.". The SDK is "DA14681_WRBL_v_1.150.6"
Thanks in advance
目前我使用DA1458x_DSPS_v_5.150.2的蓝牙主机扫描，扫描终端设备，发现有个问题：在扫描开始－－〉扫描结束，会出现多次扫描到同样的设备，这个正常吗？
PS：
1、奇怪的是开发板上好像不会有这个现象，我这个是自己画的板，用的外置天线。请问跟硬件有没有关系？
2、扫描开始－－〉扫描结束是多长时间的？我好像没有找到相关设置？
I want to know that how to design the matching circuit.
该文件是我们完成的天线和匹配电路设计。我们使用了其他人的匹配电路。但我们需要进行演示，以便我们需要知道如何设计匹配电路以及如何选择电感器和电容器的值。
我的主板上面的工作流程：DA14580作为从机与另一个型号的单片机进行串口通讯，DA14580由外部上升沿电平触发唤醒后接收串口数据。接收完数据后进入休眠。外部主机每隔1s对DA14580进行一次唤醒并以9600波特率发送8个字节的数据。之后DA14580进入extend sleep 模式。
我用多个样机进行测试的时候，发现串口通讯5分钟左右后，DA14580的功耗不再动态的变化而是维持在400ua左右。 跟踪发现用于定时使DA14580进入extend sleep 模式的软件定时器被杀死了（失效了），导致了DA14580没进入extend sleep 模式，此时DA14580功能还是正常的。进一步跟踪发现其他所有软件定时器也都失效了。
一开始我怀疑是低频RC（32Khz）不稳定，于是我在主板上添加了32K晶振时钟，结果并没有改变。然后我又进行了进一步实验，发现只串口有收发数据的时候，才会出现5分钟左右软件定时器都被kill的情况。如果串口不收发数据则软件定时器工作正常。
近一步跟踪发现，如果不让蓝牙唤醒和休眠（每1s内蓝牙唤醒大约唤醒100ms然后进入休眠）而是一直唤醒就不会出问题。
请问上述问题我该如何追踪？
Hi,
I'm learning the ble example, named ble_app_peripheral. When running the hex image, from the cellphone app, such as Lightblue, it displays there are 2 services. When i enable bass service, still showing 2 services ，but actually there are 3 services.
How to correct it?
Best regards
Fei
