Directed advertise

Tue, 2021-02-23 15:36 -- adam.stroz


I'm trying to run direct advertising on the Da14531 chip but I can't see it working, below is the code which I added  (based on empty_periphertial_template):

static const struct default_app_operations user_default_app_operations = {
    .default_operation_adv = user_advertise_operation,
void user_advertise_operation(void){

app_easy_gap_directed_advertise_start(0);//0 and 1 have the same result


I tryed to re-start advertise by add this part of code to app_direct_advertise_complete fun.

Works without BLE active

Thu, 2021-02-18 18:59 -- adam.stroz


I would like to know if it is possible for da14531 to work without BLE enabled?

My scenario:
Step 1: The device starts up without any advertising (BLE off), performs some operations and goes to sleep.

Step 2: When it is woken up at certain times by the RTC (to do some operations), it turns on but without BLE on.

Step 3: And finally when I press the button, the device should turn on with advertising (BLE on).

Is possible to work without any BLE activity? I tryed to change this part of code:

PlatformIO support

Wed, 2021-02-17 22:25 -- gerard-dl

hi guys,

I bought the DA14531 devkit and was impressed with the hardware, but very dissapointed with the software/IDE tools needed to work with it.

I am an experienced desktop developer (I use Xcode, VisualStudio, Eclipse, NetBeans), but am I just starting with microcontrollers, so I might be spoiled...

In he end instead of using DA14531 I decided to go with ESP32 only because they support PlatformIO.

I hope to see you start supporting PlatformIO/VisualStudio/Eclipse soon!



Quadrature Decoder - select appropriate type

Mon, 2021-02-15 19:34 -- adam.stroz


I have a small questions about using rotary encoder with DA14531. 

How to choose the right type of encoder? 

What parameters to pay attention to? 

Whether this encoder will work with the built-in decoder (pdf in attachment)?  I wrote a simple program and it counts impulses wrong (e.g. 12 24 36)

Sample code here:

SBC audio pass-through

Fri, 2021-02-12 23:40 -- reaverrui

Hello World, I would like to use the DA14531 to connect to a smartphone as headphones using SBC codec. There would also be a secondary Cortex-M4F micro on board which would do the processing of the audio data. The two connected via SPI for data transfer, and I2C or UART for commands. 

Is there any reason this wouldn't be possible? 


Also, is there any dialog examples using SBC codec?

Thank you.


"scatterfile_common.sct" Problem for Simple beacon Example

Fri, 2021-02-12 15:02 -- ozgurkoc

I have a DA14531-00FXDEVKT-U (Development Kit-USB). I want to do the "Simple beacon Example" example. I ran [python dlg_make_keil5_env_v1.006.py -sdkpath "C:\....\DA145xx_SDK\"]. But it is saying that the scatterfile_common.sct is missing. I am using the latest version SDK ( and Python (3.9.1). Can you help me?

Thank you in advance.
