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 all,
In my current project I have 7 sensors, each hooked up to an own nrf52. I am polling between 8 and 28 byte(depending on operation mode) of data in 10ms intervals...
I created a copy of bluetooth/peripheral example and copied the nRF5340DK board files to make my custom board definitions. The guideby Øyvind A. Sandberg is really good here...
Hello All,
I'm interfacing a temperature sensor ds18b20 with nFR52840, which uses one wire protocol.
I'm using this repo https://github.com/DSysoletin/nrf52_ds18b20_example...
Hello! I wrote my own version of the bootloader for nFR52832. If I go into the loader, check the application and switch to its execution via nrf_bootloader_app_start (), then...

I need to adjust the Flash and RAM to accommodate bootloader and Softdefice and read the tutorial at the link https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting...
- I reviewed Android-nRF-Mesh-Library code, and i saw this logic: first, it used Provisioing Service, when provisioning is completed, it disconnected with nrf board, and then...
Hi!
I'm developing code for Central device on nRF52840. SDK 16.0.0 SoftDevice S140.
Peripheral is a Bluetooth mini printer. I can connect to it and print. But when I try...
Does SoftDevice S113 use interrupt priority level 4, or a re the actual S113 interrupt priorities 0, 1 and 6?
As I understand it, this says S113 uses priority levels 0...
