Development with OTP
I know, I can't write a program to OTP just one time.
First, I'll write a program to flash ROM and test the operation.
I have a question.
Does it operate correctly, if I write the same as flash ROM program to OTP?
蓝牙鼠标HID下有三个相同UUID但是传送的数据不一样怎么回事
SDK包是，DA14580_MOUSE_3.70.2.63。
我用nRF Master Control Panel on GitHub这个安卓APP来连接蓝牙鼠标时，发现：
在Human Interface Device （UUID为0x1812）
下面有三个UUID都是0x2A4D，但是他们的传输收据不一样。
第一个用来收鼠标偏移值，第二个收按键值，第三个就不知道了。
现在问题在于
1 客户在自己定制的app上，如果想直接通过读取UUID的方式去获取鼠标的数据（按键，xy轴偏移），那么他们要怎么区分这三个相同的UUID？
2 我想是不是只要读0x2A4D，通过数据长度来区分？因为我发现鼠标偏移是8字节（0b 00 0c 00 00 00），按键值好像是2字节（00或者01或者02或者03）
what's the internal resistance of ADC
can you give me a sheet that ADC Resistance varies with temperature .Becasue I have measured the internal resistance is only about 22.2K.the value is so little,
have a big influence to my device
thank you
RCX20K_BIAS
Hi. In the release notes for the new SDK 5.0.4 I see that RCX20K_BIAS has been changed in order to get a more stable RCX clock. Now I just wonder, how much different does this really make? Is it an important/significant update? Have you seen conditions where connections constantly failed but after this fix they don't anymore?
Systick.c这个文件里面是不是定时器？
Systick.c这个文件的函数好像是定时器。如果用起来跟app_timer_set有什么区别？
比如系统睡眠了Systick还继续计数吗？
secondary_bootloader application configuration settings
Hi support,
I add SUOTA service to my application with bootloader in OTP and images inside SPI flash. It does not work when I burn the bootloader into OTP and image into the flash according to the "AN-B-010 DA14580 using SUOTA" document.I don't change anything of the secondary_bootloader project,is it right? How to set the "AES_ENCRYPTED_IMAGE_SUPPORTED" and "SUPPORT_AN_B_001" for bootloader inside OTP and flash respectively? By the way, it is difficult to understand what are secondary bootloader and dual image bootloader, could you please make it more clearly? Thank you!

DSPS SDK 5 sleep configuration
Hi,
I am using DSPS sdk 5 central mode. I am facing problem in extended sleep mode. I have set following parameters
#undef CFG_DEVELOPMENT_DEBUG
#define CFG_MEM_MAP_EXT_SLEEP
sleep_state_t app_default_sleep_mode = ARCH_EXT_SLEEP_ON;
controller enters in sleep mode but it still consumes 260 uA current. I am watching current on smart snippets.
please suggest how can i reduce current.
thanks,

non-blocking SPI slave implementation
Dear reader,
我想实现SPI之间的通信the DA14580 and a host mcu, for data package transfer. The DA14580 is acting as a SPI slave (8-bit, POL=0, PHA=0, bi-directional FIFO, DREADY interrupt line, own flow control). As a starting point I used thespi_hci.c. However, I noticed that thespi_hci_write_func()is blocking and is not - as thespi_hci_read_func()is - interrupt based. I am trying to make the write function interrupt based, however some things are not clear to me:
Feature Request: Multiple packet advertising
Hi,
This feature request is related to:http://support.dialog-semiconductor.com/starting-multiple-advertising-in...
We have switched to SDK 5.0.4, and we are struggling to implement a feature that may be needed by others too.
We basically want to advertise more than the 62-bytes limit (including headers, etc.).
The GAPM_START_ADVERTISE_CMD command allows to set a single adv_data payload and single scan_rsp_data payload.
