Hello,
We upgraded our project to nrf connect sdk v3.0.2 from v2.9.0 and can no longer use pin 0.00 and pin 0.01 as gpio. The problem seems to be in the nrf53 soc.c file...
Hi,
I am testing the Bluetooth function on my custom board with nRF5340 CLAA chip. I have tested the clock, I2S and SPI on this chip previously and they all worked perfectly...
I'm having some trouble connecting to the onboard jlink with the NRF9151 devkit that I've recently received. The quickstart seems to detect the NRF9151 dev kit, but when I...
We have been evaluating the nRF5340 and nRF7002 for use in a new product and we are currently looking at our Wi-Fi FOTA options. For reference, we are using an nRF7002 DK...
Hi Nordic team,
We are developing two types of devices based on the Zephyr examples:

Our design uses the following...
Hello,
I've a battery based device that uses a buck/boost to efficiently use entire battery voltage range (4.2-3.0) . This component have a low quiescent current between...
Good afternoon! As the NRF7002 takes about 400ms to start up from shutdown, we would like to use the very low power deep sleep function for quick startup. Unfortunately, due...
Hi,
I need to write a validation document for nRF51822 . The first step need is the specification for its calibration. But I couldn't find it in your website. Can you send...
