I use `west debug` to start `gdb` for debugging nRF5340DK
when I use `west build` to update the image, I use `load` command inside gdb CLI, the new `zephyr.elf` is loaded...
I don't know if this is a hardware or a software problem. My nRF52832 code runs correctly on a PCA10040 development board (UUID = E9:4A:AF:04:D2:16). My custom hardware advertises...
My software sent 2422, and I saw it on the net. 2417 also has one.
And the same goes for everything else, which is basically 5M off.
What is the reason?
Hi all,
I am working on troubleshooting intermittent application resets with an nRF52840 and nRF Connect 2.6.1. Codebase is small, complexity of the project is still small...

I'm using 'NRFX_LOG_INFO' for debugging purposes. However, the code seems to stop progressing when 'the NRFX_LOG_INFO' statement is removed from the section below...
Hi,
I am using an nRF52 DK board to perform some very simple tests. All I need to do is receive a line of text over serial, perform some calculations and return another...
HI
I'm trying to use lpcom to detect when the battery voltage is dropping.
The configuration is as follows: 5V battery voltage output is reduced to 3.0V through LDO...
For my application I need the UART TX/RX pins pulled low until I am ready to turn on the UART. Is there a method in Zephyr to do this? Currently when Zephyr starts it reads...
I saw some similar question, but none is what I am experiencing.
I notice some weird behavior while testing DMA mode, so I made a simple setup:
I set the DMA buffer to...
Hello everyone,
I have two devices: a Thingy53 acting as the peripheral and an nRF5340 acting as the central. I have a characteristic in a service that I want to modify...
