We need to set a GPIO pin in MCUBoot to activate an external USB hub chip so the USB DFU will work. I would like to do this with code in our project rather than directly modifying...
Hello,
I’m working on a Zephyr-based application using the nRF5340 where I need to optimize power consumption. The intended behavior is:
The device should stay in...
According to the nRF52832 Product Specification, “A step increase in supply voltage of 300 mV or more, with rise time of 300 ms or less, within the valid supply range, may...

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
I'm currently working on implementing OpenThread on our custom board based on the nRF5340 along with the nRF7002. While building the project, I'm encountering the following...
I am using zephyr_nanopb_sources to add some protobuf files to my app target, and this works fine in a normal build without mcuboot. However, when building with mcuboot it...
Hello Nordic Team, I recently encountered an issue similar to the one discussed in the post .After testing multiple device types, I found that only generic switche is recognized...
Hi,
I am developing for the 54l15 using nrf connect version 2025.5.92 Last Updated 2025-05-15, 10:08:43 and it's starting to seriously frustrate me.
The nRF Connecot for...
Hello,
I'm here again because this time I need to autoconfigure (configuring from inside program, no use of any nrf app) heartbeat destination node and source node.
For...
Hi,
We are currently CE certifying our product, and the test lab requires a fixed frequency firmware for the device. Are there any generic samples for this within nRF Connect...
There is a possible typo in the nRF5340 DK documentation.

In the top picture...
Are there any good tools/apps to commission/provision an ble mesh application that is NLC compliant. Silvair is a great option, but is a closed ecosystem. We are looking for...
We are using the nRF5340 and our use case makes full use of all 4 shared peripherals for SPI and TWI as well as SPIM4. We want to add UART over USB and I was able to port...
Hello, we're currently developing BLE devices with PCA10040 and nRF Conenct SDK 2.9.0.
During a series of experiments, we found that with the same hardware and the same...
Hi
I am try to developing ble mesh gateway to connect and controll different nodes using nrf52840. Please give guidline to do this. I think proxy node is bridge of host...
Can the NRF54L accept a CMOS output clock signal on XL1? The NRF52s could do this via clock source register settings but such a configuration is not listed in the NRF54 datasheet...
Hi,
I am trying to use nfc_t4t_lib and I have some issues because processing incoming data takes some time (around 100 ms) and therefore sending the response occurs late...
Hello, I have been going through the DFU and FOTA lesson in the Nordic intermediate course. I see that there is a FOTA support for a scenario in which we want to update a...
Good day,
I tried to build the standard Nordic application: Blinky for the nrf52840dk/nrf52840 board from the following directory on my PC: c:\ncs\v2.9.1\zephyr\samples...
