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...

Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
Hello, is it possible to somehow use RTC0 peripheral onboard an nRF9151DK to store real time so it will be available (sustained) even after resetting the device? As far as...
Hi, I used nrfjprog -e to the nRF54L15DK and problem is in Programmer log.txt How to recover nRF54L15DK does we need to update the nRF5340 JLink debugger?
I configured VBUS with a 1500mA limit. In theory, VSYS should deliver something similar to this. The VSYS output is 5V; it powers some LDOs in my project, which consequently...
Hi, I’m trying to generate a PWM signal directly using the nRF5340’s PWM peripheral registers (not using Zephyr’s pwm_dt_spec or driver API).
The LED turns ON correctly...
Hello,
I am trying to adapt the "Interfacing with a sensor over SPI" example from the nRF Connect SDK Intermediate Dev Academy course in Lesson 5. When I run the code as...
Hello, I am trying to convert my codebase from segger embedded studio to nrf connect. I am currently working on the spi section of my codebase.
I am communicating from...
Since it was brought up in the Webinar today, that the nRF54LM20A is not recommended for use with LE Audio due to the lack of an Audio PLL, I was wondering that the Audio...
Hi Nordic Dev,
We are experiencing issues with sudden connectivity loss and hardlocked devices 1,5 years after product launch. We are currently suspecting the flash storage...
Hello,
I have a Thingy:91x.
I flashed a BLE central program to the nRF5340 on this device.
However, I get an error initializing BLE. I've confirmed that this program...

Hi there,
I have been trying to implement a low-power mode that basically suspends UART, I2C, etc before entering sys_poweroff() when critical battery level is triggered...
Hi,
I have several field devices using the LTE Link Controller library with nRF Connect SDK v2.5.1. Most of them work fine — they are programed to connect every hour. However...
