I am working on the (old) IoT project with SDK 5.160.1.19 (with modified hardware/FW).
I have a blue LED which blinks when it is advertising, pretty much the original code of the IoT project.
Sometimes the LED will stay turned on when the device goes to sleep. I assume it can happen whenwrbl_env.led_tmr_state = 1in this moment. After shaking the sensor (motion wakeup) the LED continues to blink as it should.
Hi, I'm using STM NucleoF401 with Arduino Shied custom expansion board that use a SLG46824 device.The NVM programming code was ported from AN-CM-255 SLG46824_6 MTP Arduino Programming Example (MTP_Programmer).
I have successfully programmed my SLG46824, and my custom board is working fine.
But once programmed, I'm not able to reprogram the device. For example, I tried to change the I2C address from 0x10 to 0x20 (writing 0x02 into register 0xCA of NVM), but nothing happens, the device answer always at address 0x10.
When I open the "SmartSnippets Toolbox" there appear a popup telling "SDK configuration xml file could not be found. Using bundled support packs"
为“SDK根导演RY" I left the default directory by installer
Where can I found the "SDK configuration xml file"
Thanks
Is it possible to programme the DA14583 internal FLASH using the SWD interface?
I have my custom PCB connected to the PRO Dev board with the following connections:
- SWD
- GND
- VCC
- SWCLK
I can load my programme and run it from RAM no problem

Hi Dialog
Is there a demo for the HID Bluetooth keyboard of the DA14580? If I use uart to transfer data, the mobile phone uses the HID routine to receive, what services need to be modified in the HID demo?
Dear Dialog support team,
I'm using DA14580 with SPI,and my .HEX is around 40KB, so I have to use external flash.
But the program doesn't work in this case, if I test a program doesn't use SPI, it works.
So I have the following questions:
1) Is it possible for me to use SPI external flash and also use SPI after booting?
2) If I can use SPI after booting, how to remap the pins?
3) If I use DA14585 which has enough OTP space,can I remap the pins randomly/or any rules to remap pins ?
Hi Dialog
请问有没有DA14580的HID蓝牙键盘的例程，如果我使用uart传输数据，手机使用HID的例程接收，需要在HID例程里修改什么服务？
Hi, I'm trying to program the GreePAK 46824 mounted on my STM32F401custom board. The first programming of device has worked properly. After this, I tried to reprogram the device using this sequence:
- NVM page nn erase
- NVW page nn write.
After make this, I have the following issues:
- 1 the device answers with I2C address = 0x00;
- 2 reading NVW pages returns all bytes = 0xff
- 3 the device is not working
Where I have wrong? Can we help me to solve this issue?
Many thanks in advance!
Kind regards

DA7212 has been used as slave I2S mode. For PLL to operate in SRM mode, does it requires continuous MCLK? In our case MCLK is not continuous, MCLK is generated when ever I2S transmit/receive occurs. So, I wanted to know do we require continuous MCLK?
our project enable watch dog mechanism,
but when system reboot,how can i know the boot reason has been watch dog cause reboot??
Is there any register that can read boot reason?
thx.
