Hi There,

I'm using the DA14585-00ATDEVKT-B Development Kit - Basic.

I have the support pack "6.0.14.1114" sellected and no SPI options are available in the "Settings and Virtual COM Port" window.

"UART only" and " JTAG" displays available options, but I cant get the SPI to display any COM Ports.

Can you please let me know if you have any ideas on how to procede?

I've attached a screenshot of the window I am refering to.

thanks for your time!

Kind regards,

Nathan

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.

Cheers,

Hello

I was looking on your Datasheet for this component (DA14585-00000VV2.) any reference that tells me if the solder balls type are collapsible or Non Collapsible type.

Could you please cofirm what type is this device? I'll appreciate your quick support on this matter.

I understand that the DA14531 supports 1 Mbps operation and not 2 Mbps data rates. What is a practical maximum actual data rate in a good near-field situation? I am assuming that a large value of MTU will be beneficial under these conditions. A possible use case would be trying to transport up to 1 gigabit of data in one direction with minimal data in the other direction. A 16 Mbps SPI data link to the chip is expected with negligible time spent negotiating that bus.

Hello

My team and I are designing an automotive security box, and we have to design a key to unlock the box.
The key needs to :

-Work without buttons

-Last at least 1 year with a 210mAh battery

-Be secured (send rolling messages for example)

I saw in the Smartbond Product Family presentation document of June 2020 that the DA1469x is a good choice for Automotive Keyless entry, so are there some reference designs for hardware and software that could fit my requirements ?

Thank you in advance.

Hi there

It would be great if your team could make your MCUs available to simulate in Proteus. It would make design and debugging easier.

Warmest Regards

Hello

I have an application developed using ESP32 where the application connects to a vehicle using CANBUS reads Speed, RPM, temperature and some 10 other information every 100 ms and update the BLE characteristics for each parameter, it only have 1 user connected a few times a day.

I would like to know if the DA14531 module would be capable of running this application? I plan to interface the DA14531 with an external SPI CANBUS controller

Thanks

Hi,

I was looking for some feedback on determining the supply voltage for the components in the DA1469x series. I am aware that there are maximum and minimum thresholds, but I am unsure how to determine the maximum and minimum cutoffs for my specific application. To provide some additional context on a higher level, the MCU of my intended application will use a Li-ion battery, which will power a display, an IR proximity sensor, and the memory components of the MCU. My thought is that I need to finalize my hardware peripherals first, but I was wondering if there are any other approaches in determining the proper power requirements.

If you can help me, I would truly appreciate your response.

Thank you.

Hello, We are realizing a little board with DA14531 so to add BLE interface to our products. On 10 first samples rrealized only one is able to be programmed via JTAG interface using SmartSnippets Toolbox.

The error is a missing communication:

...

Could not measure total IR len. TDO is constant high.

No known chip found while opening JLink connection. Terminating proccess...

It appears like a soldering issue. With an XRAY control the solder of DA14531 does have some less tin and uneven solder, but it is difficult to judge whether all the solders are open-circuit.

I would like to ask you if you think this issue in your opinion depends only on soldering or if you suggest other controls.

Do you have any suggestion about the soldering process (e.g. temperature profile)?

Would you be available to check schematic and layout?

Thank you in advance.

Hi Dialog Semiconductor,

I am planning to use Polymer Lithium-Ion Battery with 3.7 V to power up the DA14531 module for buck mode operation. Will it be ok? or do I have to stay within the 3.3 V limit?
