I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.

Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
I'll start off by saying, as a new developer, Nordic has made an absolute mess out of the docs. The default example 'TWI_sensor' starts with easyDMA enabled, meaning it defaults...
Hello,
I am using nrf5340 module with external hardware audio codec to test stereo audio output.
I use nrf5340 module as the headset to connect with Pixel 7 mobile phone...
Hi Nordic Team,
The default stream direction is undirectional, so I add CONFIG_STREAM_BIDIRECTIONAL=y in prj.conf, then use " python buildprog.py -c both -b debug -d both...
Hello,
We have a fitness application that employs concurrent use of ANT+ and BLE communications on an nRF52840, that we wish to port to the nRF5340. The product brief...
I created a custom bootloader based on the SDK 15.3.0 secure bootloader. At location 0xFF8 I defined the uicr bootloader start address as 0xE4000 but my bootloader actually...
Hello
I was trying to add BH1749 I2C Sensor for existing Mesh_Sensor example to get RGB values like shown in this Light_Sensor example. Couldn't decide how to do it and...
Hello all,
Environment: nRF52840-DK, NRF SDK V15.0.0, SoftDevice s140 v 6.0.0, ARMGCC building with Makefile
I am currently trying to combine the examples of the USB and...
On a 52840 USB stick, I successfully tested the "observer" demo app.
Now, I tried to extend it by enabling CONFIG_BT_EXT_ADV=y which is supposed to print some details about...
Hi, I got strange error which I can't to fix.
From time to time, I get the same readings from every function which counts the CPU cycles. They all base on DWT_CTRL. Board...

Building the example project gives build warnings:
Could you help me understand...
Hi,
I am trying to implement a Low Power Wireless technology to get sensor values from more than 10 devices at a time. On doing research, I found that the Thread Topology...
Hello, we have built a custom nRF9160 board with different populations for the GPS antenna, now we would like to do some tests to find out which variant offers the best signal...
Hi!
The posts I've found regarding this were quite old, and they mentioned features which then were coming.
So I'll ask anew: Is it possible to use AT-commands through...
Hello,
I would like to ask you if SoftDevice S132 v.7.x.x allows Master-initiated Feature Exchange procedure?
