Set DA14683(AQFN) USB pin P1_1 & P2_2 as SPI MOSI & MISO pin

Fri, 2020-07-03 05:30 -- kuda

HI! PM_Dialog,


      I have custom DA14683 boards and got problem about set DA14683(AQFN) USB pin P1_1 & P2_2 as SPI MOSI & MISO pin.

      For pcb layout issue, my custom board need to setup P1_1(USB pin) & P2_2(USB pin) as SPI MOSI & MISO pin.

      I had trace SPI MOSI & MISO signal output and input by oscilloscope. It can trace waveform to verify hardware is work.

      But I can't get any data from SPI read function.

DA14683 mesh SDK

Mon, 2020-06-29 13:29 -- MathieuB

Hi all,


I have bought a DA14683 devkit pro to use its mesh functionalities.

On this webpage (https://www.dialog-semiconductor.com/products/smartbond-bluetooth-mesh-sdk) there is a link to request (by email) the mesh SDK.

I have sent an email (3rd June) but have received no niews since then.

Could anyone tell me how I can have acces to the mesh SDK ?


Thank you in advance.

da14683 hangs in ROM while booting

Thu, 2020-06-25 09:02 -- marss

I've written a tiny program which toggles an LED for the DA14683 Pro Development Kit. The program is running from the RAM. When I upload this program manually (without the IDE) this also works fine.

When I upload the exact same program (with the exact same debugger) to our board (an LED is also at P1/5) the CPU always get stuck in the ROM at address 0x07f01dfc (which is a loop onto itself). Maybe this is the "Wait Forever" part of the boot sequence.

write more than 8 times to VES flash?

Wed, 2020-06-24 12:14 -- andoridfm2013

hi, Dialog,

i wonder what will happen when i write too many times into VES. For example, assuming VES partition_entry_size / AD_NVMS_VES_MULTIPLIER = 128 / 8 = 16 kBytes.  All space will be taken after write 16kB data into it for 8 times. What if i write more than 8 times? shall i erase whole VES 128kB flash before writing the 9th 16kB?

thank you.

DA14683 客製修改版的電路板

Tue, 2020-06-23 14:46 -- kuda


          我們依據 DA14683 development kit Pro電路重新設計 DA14683 電路板,在更新 firmware遇到問題.

          我們使用 DA14683 development kit Pro 作為 JTAG工具,並對以下接點連線         

DA14683 development kit Pro  --> 我們的DA14683 電路板

JTAG interface

          J3-SWCLK/ADC7/P2_4 - > SW_CLK pin of custom board.

          J3-SWDIO/ADC4/P0_6 - > SWDIO pin of custom board.

UART interface

          J4-ADC0/P1_2 - > UART_TX of custom board.

          J3-P2_3 - > UART_RX of custom board.

Power in
