I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use

2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
I am trying to make the nrf9161 go to very low power mode for 10 seconds and then come back online.
Actually I would not mind if it were to start all over again when coming...
Hello,

Dear Nordic
We are evaluating a wearable device and plan to use nRF54H20 be our MCU,
Since our device will be a small form factor and Nordic not released datasheet yet...
Hi, I'm working on nRF9151 on custom board, NCS 3.1.0 and I'm building application with TF-M enabled. I've encountered quite a strange problem. If I remove all UART instances...
Hi,
using nrf sdk connect 3.1.1
using nRF54L15-PDK evaluation board.
Steps to reproduce issue:
1. Setup my board into low power. my branch mark is ~2.9uA.
2. Perform...
I use BLE for one-to-many connections. Usually, the peripheral device should first broadcast, then establish the connection for communication, and finally disconnect. However...
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.
