Hello everyone,
We are currently working on a project that uses the nPM2100 to power an nRF52840. Our application requires automatic enabling break-to-wake mode each time...
Hello DevZone,
One customer used Timer+PPI+GPIOTE to simulate an UART. Now it works fine.
However, when there is other timer's interrupt, the simulated UART may lose some...
Hi, I just received our nRF54LM20DK, and am trying to get a functioning BLE sample on the board. Many samples are supported, however I have not gotten a single one to work...
Hi,
I have a question about SPIM. Is it possible to have two events via DPPI that will start different SPIM transfers for the same SPIM channel?
What would happen if a...
I have the board: NRF52840-DK PCA10056 3.0.3 2026.5 1050266921
Is it possible to use OB J-Link to debug STM32/RP2040 MCUs connected to P19/P20? Or OB J-Link support limited...
Hello, My nRF54L15-DK has suddenly stopped working, and it appears to have a hardware-level power failure.
The board was working normally the previous day while running...
We are using CMakePresets.json extensively in our project and rely on the condition field to control which presets are visible depending on the host system.
However, it...
Hello,
We are using the nRF52840 with SDK 17.1.0, SoftDevice S140 v7.2.0, and the secure bootloader (nrf_bootloader.c).
Our application relies on reading NRF_POWER->RESETREAS...
Hi there,
One of the functions of the DECT MAC layer is to allocate radio resources to RDs. According to the standard, the MAC layer does that using special beacon messages...
Hi,
I'm working on a wireless sensing project using the nRF54L15-DK (PCA10156) where I need continuous RSSI measurements at 2440 MHz. I'm accessing the RADIO peripheral...
Hi,
I am working on an nRF52832 using nRF5 SDK 16.0 and I am seeing inconsistent behaviour in the RESETREAS register. During a power-on reset, the value is usually 0 but...
Hi!
We are building an application for Thingy91X and noticed that there is an overlap between the shared memory between the app and net mcus, sram0_shared, and RetainedMem...
Hello, I am working on a project using nRF52832 with Zephyr RTOS (NCS v2.7.0) and MCUboot. I have implemented BLE passkey-based security (BT_SECURITY_L3) on the device. I...
I bought an NRF52833 DK development board. I want to conduct an AOA experiment, but I don't have an antenna array. I was told that I can find the schematic and PCB files for...
