connect wiht multiple central devices

Mon, 2020-09-21 07:25 -- hugangbin


Hi, Dialog

I've read some code about DA14531, I do not know much about this device.

I wonder if DA14531 can be connected with multiple central devices at the sametime?

And How much central devices can support?


To Verify and check the external Falsh(24C256 - Atmel) functionality with Da14531

Hi Team,


Currently I am working on custom designed PCBA( Da14531) with multiple sensor on same board.

To flash it on OTP memory , I would  do with Falsh and  I tried with Atmel 24C256 with I2C protocol.

Able to upload my hex file into flash memory as mentioned on above device using smartsnippet tool.

It is not booting from flash.

also I observed that list of device to support for the booting, for I2C the device M24M01 - R from STMicroelectronics.

will it work only for the above device?

Please guide me to resolve this issue.

用Smart Snippets 烧写外部存储器时 怎样选择SDK Header file

    1、在工具Smart Snipptets Tool 中的 EEPROM Programmer选择“Make Single image”装入*Bin文件后,“Select a SDK Header file”要选择哪个文件?    

    2、 烧录后“Key”和 “IV”是否可以用工具读出来?



Battery Bounce DA14531

I am powering the DA14531 with a small coin cell battery.  Sometimes when I plug in the battery it appears that the processor does not boot up or is stuck in reset.  I am wondering if it is experiencing the same battery bounce issue as the DA14585 processor?  How do you suggest mitigating the issue since the DA14531 doesn't have a dedicated Reset pin.  The reset pin is currently being used as the MOSI signal to the external flash.



Building a flash-booted custom board

Hello, valued Dialog staff members!

I developed an application, running on a DA14531, which drives an SPI connected device. All operations work fine, the Bluetooth BLE functions also work, I can connect and get notifications on value changes.

All software fuctions are developed using Keil and are running from device RAM.
