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.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
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...
Hi All,
I am currently designing my PCB using nRF52840 chip.
I was using the footprint downloaded which was in nRF52840 dongle pcb library given by Nordic. During DRC...
Hello,
I am using Nrf51822.
I am using sd_110/application/bootloader, etc. in SDK_10.0 without problem.
Recently, migration to SDK_12.3 / sd_130 is in progress to...
How wide are the peaks? I know that it depends on many factors how high and long the peaks are. Currently we have measured peaks of 450 mA for 40-50 ms in our application...

Hi,
I'm comparing the nRF9160 DK and Thingy 91. The purpose is to copy the LTE RF design for a Band-20 application. The GPS will not be used.
Question: Is the complexity...
I have bought two thingy 91 to develop the tracker using GPS and accelerometer. I did all the step by step to load pre-compiled hex file given on the website. Then I created...
We are making customize the wearable who records the data from the accelerometer and GPS sensors and sends it back to our server. SO, we decided to use thingy 91 chip has...
Hi,
We built the Blinky sample with NRF Connect SDK 1.3.1. It works fine on NRF52833 DK, but when flashing on external custom NRF52833 board the firmware won't start without...
Hello,
I am trying to integrate the Unity test framework into our project and running into issues with how to add additional test files. Nordic provides one example project...
Hi,
I am developing a project where I have NRF52840 as a device and another NRF52840 as a BLE USB dongle connected to PC.
I have to improve the BLE data rate between the...
Hi,
I have a NRF52840 device connected by BLE to another NRF52840 BLE USB dongle connected throw USB to a PC application.
I want to synchronize the RTC on the connected...
