Three software seems to perform OTA DFU: nrfutil command line, nRF connect from desktop, nRF connect from mobile
Do I need all three of them? Are they part of Nordik SDK...
Hi,
I am using an Adafruit nRF52840 Express with a sensor board attached to it. I'm noticing that my sensor IC is reading about 3-6dB higher noise in the 10-50Hz range ...
Hello,
I want to program and debug a custom PCB using the nRF52832 SoC and nRF52 DK. I plan to use this setup:
From what I understand, the GND detect will cause the...
Hi Nordic team,
We are busy testing the throughput of the nRF9160. We are having issues installing the NCS at this stage, and was thus provided with a HEX file of the Serial...
Hi Nordic engineers,
I am using west to build the nRF NCS, my own project which is adopted from samples. Using Powershell (win10) to run west commands as below.
I need...
