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...

A while ago I asked this question devzone.nordicsemi.com/.../.
Yesterday I re-installed MDK 8.11 after a computer crash and I had IAR version 7.60.1 and version 8.11.2...
Hi,
I need to design a small nRF52 board On 24mm Dia 2-layer PCB, same like nRF51822 Bluetooth Smart Beacon Kit (nRF51822 Coin-Cell design). Please find the attached Schematics...
Hi everybody.
I encountered issues with the formentioned setup. In my project I'm using latest SDK 13.1, softdevice S132 v.4.0.2. I'm compiling the project with latest...
Hi to everybody,
I am working with a custom board based on the nrf52832, while trying to integrate to my existing application the DFU functionality I am having problems...
I am trying to measure the ADC on all 8 ADC pins of the nRF52 on the PCA10040. I'm noticing quite large amount on noise on floating lines (up to 0.6V). However my biggest...
We have a device with a main MCU connected to a NRF52832 for BLE communication. Our device have Battery, Heartrate and a custom service. The first implementation used a Sparkfun...
I am trying to decide what Nordic solutions would best support the application throughput requirements seen below. Distance requirements are low (1 meter each link).

Hi there,
I have nRF52840-Preview-DK eval board. I have downloaded the “SDK 13.1.0”. I was trying out the power management example under the folder “..\nRF5-SDK_copy\nRF5...
The 51822 PS mentions a "Nordic Trace Buffer" but doesn't seem to elaborate. I assume this is similar to the Cortex Micro Trace Buffer? Is there any more documentation available...
Hi I'm looking forward to hear if I could program an nRf51822 QFAA without using the development kit/board. The chip I have currently is a N51822- S4AT, from Wireless Tag...
I recently purchased a Rigado BMD-350 eval board (nrf52832) and am trying to use it for creating a simple ble remote project. I am kind of lost.
As I look through the heart...
