Hi!
I have been unable to find a single, simple set of instructions for adding MCUboot to a project(toolchain 3.0.0 sdk 3.0.0) that will enable a non-default signing key, two-slots for updating(with or without scratch). I have found a ton of pages and…
Setup: - We have a custom board using the BL654 (Laird Connectivity) module with the NRF52840 core using SDK 17.1
Issue:
- On power up we configure the GPIO 41 as an input with internal pullup (NRF_GPIO_PIN_PULLUP)
. The input in this test is disconnected…
Hi,
I tried to add a pairing PIN code feature for connection with a central device (based on the reference: Migrating to Peer Manager ) in the ble_app_uart example of the nrf5_sdk_17.1.0_ddde560 SDK, using the nRF52840-DK.
However, the following error…
Man,do you have the experience on DIY Bluetooth headset with PCA100059?
I raise this question for I hate the current product limit: limited time to run,short lifetime of battery, and poor quality of Made in China.
I think PCA100059 is powerful enough…
I am using the following version of nrfjprog on my Windows 10 machine:
nrfjprog version: 10.24.2 external JLinkARM.dll version: 8.44a
Most of the sub-commands work with nrfjprog ... BUT
when I want to program my nRF52840 board (using the onboard…
I attempted to create bluetooth central and peripheral apps using two nRF52840 boards that connect to each other and no one else using the device name. I had limited success, but often the firmware would not connect and I would have to restart it. So…
Hi,
am working on nrf52840 withst7789v custom display . I have integrated the my display code using lvgl library with PMIC code in zephyr . while doing that I have configure the backlight also but am not able to see anything on display my main.c, .…
Hello, Super quick but important question, are the SMD footprints in the nRF52840 reference circuitry recommended BOM (ie image attached) in imperial or metric units? and just curious since I'm relatively new to this, what is the convention when the datasheet…
I'm trying to use 'nrfutil ble-sniffer sniff --follow "${target} public" --port ${device} --output-pcap-file ${output} --coded --timeout 5000 --log-level info --log-output stdout --json' in a script to split up automated testing captures, where target…

I have noticed that Matter V1.4.1 has been supported from NCS V 3.0.0( https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/index.html ), but I have not found Matter V1.4.1 in github, only found V1.4.0 and V1.4.2( https:/…
Hi, I’m working with an nRF52840 DK and trying to use two UARTs simultaneously. I’ve configured UART1 for debugging (console and shell output) and want to use the default UART0 pins for communicating with a CO₂, temp, and humidity sensor. I want to send…
Hi everyone,
I'm facing an issue where MCUboot doesn't perform a swap after reboot, even though the DFU download to slot 1 completes successfully and boot_request_upgrade() is called.
My devices are in production and had no issues in the paste with…
I am getting the following build errors when working with both DFU (MCUboot) and the file system (FAT FS) together. Errors: D:/ncs/v2.9.0/zephyr/drivers/disk/flashdisk.c:533:1: error: return type defaults to 'int' [-Werror=implicit-int] 533 | PM_FOREACH_AFFILIATED_TO_disk…
Hi, We want to integrate LORA LR1110 for the final year capstone project. From the documentation we have understood that Kit is fully compactable with Arduino UNO. But SPI Chip select pin is different in LR1110. Could you please guide me to integrate…

Hi, I'm working on a project and I need the GPIOs to have 3.3V available when the nRF52840 is in deep sleep, in order to use wake-up on GPIO. So I'd like to know what the DCCH voltage is when DCDCEN is enabled and the device is in deep sleep.
Does the…
Hi there,
I have recently upgraded my software to latest ncs 3.2.0. I have noticed that my initialisation does complete but it ends up with fatal error that seems to be related to bt_enable. Please help me sort out this issue as I have tried various…
I have a simple GATT server application with two characteristics, RX and TX. In my prj.conf, I am trying to disable pairing as follows :
CONFIG_BT_BONDABLE=n
CONFIG_BT_SMP=n
I can connect to the server from a BLE scanner app. When I try to write to…
I'm pulling my hair out here. Why would syntax errors completely break the toolchain?
Every now and then ill have a syntax error which causes the build to fail, the entire application corrupts and key files are then lost.
In this state a prestine…

Hi,
Right now I'm looking down at the nrf52840 datasheet, because I would like to do a project with such MCU, but I got to the part of the integrated DCDC converters and I have a doubt.
At the…
I got a 52840-DK a couple of days ago. I installed the latest IAR Embedded Workbench (9.70.1); also downloaded the latest Nordic SDK,and then started building and executing some of the included examples. I started with "blinky",then one from ble, and…
Dear team, in my design I'm using MCUBOOT to perform FOTA DFU over BLE and I need some confirmation about the building process to be sure to do all the step in a properly way. As developing IDE consider VS Code.
To flash the device for the first time…
Hello,
We are working on Zephyr sample app Mesh on nRF52840dongle with nRF Mesh application.
After going through the documentation and few other Q&A on the portal, I was able to make the dongle to advertise the Unprovisioned Device Beacon. And see…
Hi,
I purchased a Qorvo QM33120WDK1 UWB development kit that uses a Nordic nrf52840-DK. I have been using this DK for weeks without issues, but the last time I used it I noticed the J3 port of the Nordic DK was a bit loose and i often lost connection…
