DA14531 Dev Kit Hibernation Mode

Fri, 2020-02-14 20:24 -- djames

So I've been working with the DA14531 Dev Kit Pro and I have been having trouble getting the MCU into hibernation mode. I'm just trying to do some preliminary tests and power characterization so I wanted to just use the example code. Following the instructions in the "Sleep Mode Tutorial" I wasn't able to get it to go into hibernation mode. On the test board I'm seeing anywhere from 200-400 uA depending on the voltage and whether or not I'm in buck or boost mode. Any help on this would be greatly appreciated.

J-Link Driver update on DA14531 Development Kit USB

Tue, 2020-02-11 00:14 -- drew013182


ARM Keil IDE had asked me several times to upgrade J-Link firmware before starting a debug session. I ignored the pop-up window several times and all projects built and debugged ok. I finally allowed the firmware update suggestions and it seemed to upgrade fine (100% complete, no errors), but now when I attempt to do a program/debug session I get a "No J-Link found" error. 

DA14531 Development Kit-USB interface with DRV2605 Haptic device

Mon, 2020-02-10 11:33 -- balaji

Hi Dialog,

I'm working on HID application based product with DA14531. I have DK-USB with latest SDK version. The Haptic device is from TI and adafruit has made driver files for Arduino. The device works fine with Arduino I replicated it for DA14531.Issuses faced are,

1. Write byte  of  I2C mis-behaves after some period(100 ms).

2. I can't drive my haptic device with DA14531.

3. when I read a I2C register after immediate write, value mis-matches.

This issue become major setback for our product prototyping. I need urgent help from your side at earliest.

ZOR antenna

Hello Dialog,

I am trying to generate a very compact antenna for use with DA14531 with 1mm FR4 PCB.

In your application note:
AN-B-027: Designing Printed Antennas for Bluetooth Smart    22/02/2017    2.2
there is a ZOR antenna drawing on page 20 for 1.0mm PCB. 

I have downloaded the DXF file for this antenna (ant_zor.dxf) from:
AN-B-027: Designing Printed Antennas: DXF files    04/04/2017    1.0

I have a custom board with DA 14531. I am using SDK  I  have written a simple application that reads battery status and transmitted it in manufacturing data of advertising packets with advertising interval 1s. I want to measure the current of my application and calculate battery life. please suggest any method for the same.

How to use DA14531 DK with Power Profiler to measure DUT current?

Wed, 2020-01-22 04:01 -- Jerry Cui

Hello, we have a DA14531 DK Pro kit, and want to use it with your Power Profiler tool to measure our device's power consumption. Unfortunately, based on our design, if the input voltage to our device is less than 3.5V, it won't work. But listed on your User Manual, there are only 4 kinds of voltage (3.3V/3.0V/1.8V/1.1V). Is there a way to achieve this?

Thanks in advance.
