你好,我这边有两个问题。我现在使用的是DA14531 PRO板子进行调试。


2. 在使用SmartSnippets的时候,连接上以后无法找到SPI接口,只显示一个UART口 COM10和COM11 和JTAG可以检测到一个480070645,无法检测到SPI口所以不能进行功耗测试,请问怎么解决?

Impedance matching for antenna design on FPC

Tue, 2020-02-25 09:51 -- shangze

Hi Dialog team

Do you have any suggestion how should we design the antenna and impedance matching for DA14531 on multilayer flexible printe circuit board (FPCB) based on polyimide material?

How bad the performance could be if we failed to match the impedance ?





The issues about donwload the File "smartsnippets_studio_v2.0.10.1468_windows.zip"

Hi dialog,


when I finish download this file smartsnippets_studio_v2.0.10.1468_windows.zip, I find that the file size is only 7857KB, much less than 578MB, so it can't be unzip.

I don't know why?  I had try many times, it still like so. please help check.



DA14531 SmartBond TINY™ module details (pinout; Footprint for PCB design)

Sat, 2020-02-22 18:30 -- mon2

Hello. In anticipation of this FCC approved module with the DA14531, is it possible to receive the pinout with recommended PCB pad layout so we can get an early start on our designs? If possible, Altium formatted support material will be of help. Thanks.

Advertisement stop related; issue

Sat, 2020-02-22 10:59 -- deshpandead


I am using DA14531 based custom board,with SDK am using ble_app_barebone example.

In this I am trying to stop the advertisement using function app_easy_gap_advertise_stop() in adv_data_update_timer_cb()

and commenting user_app_adv_start(); in function user_app_adv_undirect_complete(uint8_t status).But find that the code halts at __asm("BKPT #0\n").

if ((GetWord16(SYS_STAT_REG) & DBG_IS_UP) == DBG_IS_UP)
            __asm("BKPT #0\n");

Direction Finding Feature

Sat, 2020-02-22 07:29 -- erdemsimsek



Is it possible to use direction finding feature which is announced in BLE Specs v5.1 in the DA14531 ?

Does your current SDK enable to use Direction Finding Feature ?

If it is yes, Can I send connectionless Angle of Arrival packet ?

If it is no, Is it possible to send AoA packet directly communicating with RF core and is there any future plan to bring Direction Finding solution into your SDK and products?


Best regards.

Questions related to DA 14531

I am new to DA14531. I have a custom board with DA 14531. I am using SDK 

I have seen in every example following functions

2.  GPIO_init();

I have the following questions related to DA14531 and SDK

1.Does RAM retention & GPIO_init()  is necessary in every example?
2. What should I make changes in code for OTP programming?
3. For reading BD address from the chip at the time of OTP What should I make changes in code?
