Streaming frequency

Tue, 2018-12-04 10:53 -- gomezago


I just started working with the SmartBond DA14583 and I was wondering if it is possible to set the frequency of the accelerometer and gyroscope to 100Hz while streaming, and if it is possible to stream via Bluetooth at 100 Hz.

I read on the documentation that the default performance while streaming is 12.5 Hz for the accelerometer and 10 Hz for the gyroscope.

Thanks in advance


rwble ASSERT_WARNING issue

Tue, 2018-11-20 05:05 -- Rajapurerohit

Hi DialogSupport,

I am working on project where i am working on I2C base touch sensor. I have designed the custom board using DA14583 MCU and IQS333 touch sensor MCU.

I have written the firmware and now i am working on sleep mode configuration. first i have followed is by defining/Enabling the ARCH_EXT_SLEEP_ON.
const static sleep_state_t app_default_sleep_mode = ARCH_EXT_SLEEP_ON;

if i run the code, it immediately enters into attached sinppet and
hold into ASSERT_WARNING(0); line and not written any wake up API function yet.

16 Bit UUID Importance

Wed, 2018-10-24 05:45 -- nagendra81

Hi ,

what is the important use of 16 bit UUID instead of 128 Bit UUID? I know that it saves power and packet length all. but any other important use case is there ?
we are planning to buy 16 Bit UUID from bluetooth .org . are you people recommended to take 16 bit uuid ? for any normal application 128 bit UUID is enough to functionality ?
why this bluetooth .org to sell 16bit UUID for companies ? is there any advantages to companies then what advantages are we have?

Flash is not read/writable when booted from flash by advanced bootloader

Sun, 2018-10-14 11:51 -- Steve Cho

Hi Dialog-semi,

When I burn the hex file of my application to flash memory(by advanced bootloader of SmartSnippets Toolbox - SPI Flash Programmer), the application does not work on the point which read and write data to flash memory.
Of ocurse, My application is working well when is booted from RAM, booting from Keil.

I saw the previous post write "function: spi_flash_release_from_power_down()".

Reading and Writing data on inner Flash memory

Sat, 2018-10-13 03:28 -- Steve Cho

I am in Sensor project using Dialog 14583.

I have used advanced bootloader on inner Flash Memory of 14583 for downloading application PGM.

But I also will read and write data on inner Flash Memory.
1)Flash Memory address for advanced bootloader.
Offset#0: zero
Offset#1: 0x08000
Offset#2: 0x13000
Offset last: 0x1F000

2)Flash memory address for reading and writing data 0x1EC00~0x1EFFF

What is the problem?
Can I use in the same time Flash Memory for advanced bootloader and Flash Memory for read/write data?

Powering the da14583 smartbond kit with a 3.7v lipo?

Mon, 2018-10-08 17:35 -- MagicDanielle

Hello, is it possible to power the Smartbond da14583 dongle with a 3.7v LiPo? Of course at full charge, this battery will be closer to 4v and I don't wish to damage the board.

My entire project has an internal space of 17mm x 17mm x 17mm. I actually want to eventually include wireless charging, so if somebody can advise me on my options I would be very grateful. Maybe a Lipo isn't even necessary, but wireless charging with no internal access is a must.
