I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.

Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
Hello, I developed for my customer, a ZigBee coordinator in last 2019, using nRF5 SDK for Thread and Zigbee v3.2.0. I have now two questions: - is ZigBee 3.0 supported by...
I'm currently working on the nrf52832_qfax_dcdc pcb after adding a few components. I need to route to pins p0.22, p0.23 SWDIO and SWDCLK but am unable to route away from the...
Hello,
I noticed that publishing mqttsn messages with a payload larger than ~255 bytes caused an error in the mqttsn library. I think the problem comes from this definition...
I am developing an app for the 51822 with 16KB RAM, which is supposed to integrate the buttonless DFU.
I have attached the whole hex of the merged application+softdevice...
Hi Nordic Tech Support,
Our company is evaluating nRF5340 for future project. I have brought one nRF5340 DK, and I am following the online guide to build and program the...
Setup:
periheral: RF52840, S140 softdevice (SDK 15.3)
central: for test/development: laptop with Linux and BLE adapter build in, and/or Raspberry Pi, using Python testing...
I'm using the nRF5340 (currently nRF5340DK with custom hardware following shortly) and NCS 1.6.0. I'm working on a project that needs at least two UARTs and one SPI master...
Hello,
In nRF5340 project, I have two projects, one is for net core, the other is for app core. I use SEGGER to build these two projects, flash the images into the development...
I am using the nrf9160 for an OTA firmware update application. I initially executed the fota download file from the http_application_update sample project in it's default...
Hi,
I have the driver code for SPI based external NOR flash. Now I want to port the filesystem (FAT filesystem) for the same. I am using SDK v16.0 and nRF52832. Please tell...
Is there a script with which I can flash a nrf52 directly over Bluetooth. I tried to use "nrfutil.exe dfu ble -ic NRF52 -a mac_address" but it requires a board to be connected...
Hi,
In oner of new project, we planned to use nRF 52833 with BLE mesh implementation.
We are planned to use IAR 8.50.1. We have downloaded both nRF SDK(17.0.2) and mesh...
I try to use 52832 as a frequency meter to measure the bluetooth central frequency to do crystal trimming.
The target is a CW(continous wave) signal, like 2441MHz,which...
Hello, I meet some problem. The chip I used is nRF52810 QCAA, the softdevice I used is s112, I defined P0.09 as SCL and P0.06 as SDA, the TWI can't work and it stops in while...
