Hello everyone,
as indicated by this question https://devzone.nordicsemi.com/f/nordic-q-a/35692/adding-nrf52-dk-to-github-mesh-demo-for-thingys/138327#138327 I am trying...
Hello,
We are developing a product based on the nRF54L15, using BT Mesh. We also use the FLPR. For communication between the cores, we use ICMSG.
Separately, ICMSG and...
Hello!
I am completely new to embedded development and i am becoming quite desperate.
I have ordered a custom board which has an nrf52840 chip on it and a vl53l1cxvofy1...
I am using the nPM1300 MIKROE Click board with an ESP32 over TWI (I2C) . I am facing an issue when VDDIO is sourced from VOUT2 using the onboard VDDIO_SEL jumper .
Although...
I have an odd issue with an older nRF52840-DK, I can flash and read memory from the device just fine but no matter what version of NCS I use, it will not execute whatever...
Hello,
I am working on adding MCUboot to my custom board (using nRF52832 chip) to make it DFU-able. That works fine when using internal flash but never when moving the...
Hello, I'm using an nRF9151 DK with an SPI attached SD card and SDK 3.1.0.
SD card is accessed using FAT_FILESYSTEM_ELM.
Using a single thread approach everything is working...
Hi,
We are using a TMD2636 proximity sensor on our board, connected via I²C on pins P0.18 (SDA) and P0.30 (SCL). The same I²C bus also contains a TMP117 temperature sensor...
Hi,
I’ve enabled OTA firmware updates in our project using MCUboot. Before enabling OTA, everything worked correctly—our firmware received interrupts on pin P1.00 from one...
After reviewing the nRF7002 datasheet and reference design guidelines, we were unable to find the input/output characteristics and voltage ranges for PALDO, VDD_BUCK, PWRIOVDD...

I'm currently setting TX power during advertising using the following code:
This successfully sets TX power during advertising, but I need help with additional...
I have been reviewing the datasheet of the BLE audio nRF5340. It lists multiple power rails in power section.
Is any power-on sequence required for the SOC.
Also, can...
All of the following used the same power supply to power our development board and measure the current of the development board: The PPK2 I purchased measured an average current...
Hello,
I have connected the nRF52840 DK to the nPM1300 EVK , with the DK powered from BUCK1 output of the nPM1300.
When I supply 3 V or higher to the VBAT pin of the nPM1300...
Hi,
I’m evaluating the NUS (Nordic UART Service) as a way to stream and receive byte arrays.
I’ve noticed that there are two different implementations of the NUS service...
