Hi,
We've been using the PPK II for basically every IoT project we've carried out in the last few years, and it has been an incredibly useful tool.
Our standard use case...
I have the code files as shown in the compressed package. I am currently compiling them into (A: nRF7002 DK nRF5340 application MCU - Non Secure / B: nRF7002 DK nRF5340 application...
I am looking to do some testing with nuSIM. Monogoto has provided the sim profile but they say we need to obtain the SIM number from Nordic directly.
I was unable to find...
Hi, since the Nrf5340 has two identical Cortex-M33 cores, I was wondering whether it would be possible to enable the trustzone for both cores, and if yes, how. Thanks.
Hello!
We are working on a custom PCB with nrf54l15 chip on nrf connect sdk version 3.2.0.

I thought I had been extremely careful to _not_ brick the device, but apparently I did.
I created a firmware-dfu.zip file, even with appropriate keys, etc. as below.
