SmartSnippets RF Master

Mon, 2020-02-17 08:58 -- Aiden.kim

Hello, I'm Aiden.kim.

We are reviewing DA14586 products using SmartSnippets V

However, there is a problem while downloading the prod_test_586.bin file to review using the RF Master.

I checked with SmartSnippets(TM) Toolbox User Manual (UM-B-083) but could not receive sample Log Output message.

As a result of a separate review of UART, it works well.

DA14586 design questions

Wed, 2020-02-05 10:35 -- apellkof


I am about to move my design from the DA14580 to the DA14586 since the old part is not recommended for new designs and I would make use of the internal FLASH.

My understanding is from a schematics point of view, only two pins are different:

#5 (VCC_FLASH) is used to power the FLASH. On the 14580/5 it is nc.

#38 (VDD) is recommended to float. On the 14580 it was VPP and used only when programming OTP (supply 6.7V).

I hope this is correct so far?

Hi Dialog Team,

I have an EVM for da14586 and trying for firmware update for that using SUOTA android mobile application. I have followed all the steps mentioned in the document

“Tutorial 6: SUOTA example for DA14585/6”.

I have also modified the “project_multipart_binary_v2.py” script as described in the tutorial document.

Now while updating the firmware, I have received an error of “INVALID IMAGE HEADER”.

While debugging the issue I found that using the SDK APIs for SPI FLASH, Image header from the address “0x00038000” is not coming properly.

XTAL Drive Level clarification

Fri, 2020-01-31 16:11 -- mttgre

Goodmoring everyone,


i was looking at the 16MHz XTAL parameters provided in the DA14586 datasheet and i find one of them confusing.


The parameter Pdrv(MAX)(16M) is claimed to be the maximum drive power (i suppose of the DA14586) and should be minimum 100uW.

At the same time, a note says that the crystal that needs to be chosen has to be able to tolerate 100uW or more of drive level.


Connection current queries

Wed, 2019-12-11 06:12 -- karanshah28

Dear Dialog Team,

I tried to play around with the connection current as suggested in last and third last comment in thread:-




1. I found connection current to be 210uA in default connection interval configuration. (min_interval =10ms, max_interval = 20ms)

Receive data from ble advertiser

Mon, 2019-12-09 11:33 -- karanshah28

Hi Dialog team, 

We are developing a product based on da14586. Da14586 is configured as ble peripheral. We are implementing a feature where da14586 device should be notified when it goes far away grater than the predefined distance.

For that, is there any mechanism that ble advertiser can read data from central device without connecting (since connection consumes more current) and start polling on that? 


We are open for any suggestion. The primary goal is to keep the device in advertising mode and make it able to detect that it has gone x distance away. 

Issue with range extender?

Wed, 2019-12-04 12:28 -- karanshah28

Hi dialog team, 

We referred to reference manual for range extender. But we are planning to have different schematics having two main changes

1. No pwm circuit
2. P00 instead of P01 for tx en
3. P01 instead of P02 for rx

Attaching the snapshot of schematics. 

We seek for the software changes need to be done for this.
