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.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hi,
currently I'm testing several options to transfer data in broadcast manner, i.e. in fact extended advertising due to the amount of data to transmit. A few days ago,...
I want to do firmware updates over BLE. To do that I added these settings to my prj.conf which I mostly got from the smp_svr example:
This "works" but it uses the default...
Dear DevZone,
I would like to add a nrf21540 range extender to my board based on nrf52840 MCU. Our lab is based in Italy and we would need to respect the regulamentation...
Currently, I am following guide of zephyr sample: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html But when...
Hi
we are developing a successor for one of our products based on the nRF9160. One important feature is the debug UART. There are 2 ways to connect to this UART. Either...
Hello,
We have a software running on the nRF52832 which was developed with the nRF5 SDK. It contains a bootloader, S132 softdevice and our custom application.
The bootloader...
Hello,
When looking at the datasheet, we see that the modem power consumption can be really high in high power tx scenarios, 23dBm for example the modem consumes almost...
Hi,
I am looking to perform programming on a nRF52832 on a custom PCB. So far I am planning to use an SWD connection with my nRF52DK to upload my application.
1. I was...
Hi,
I'm looking for some documentation for both projects. While there inline documentation and example projects are existing, I couldn't find any javadoc (or similar,...
Hi,
I want to use two SPI instances (0 and 1) in my project. I am able to modify the example SPI project to use 2 SPI instances as in the code below and setting #define...
I'm trying to get the ADC running on an nrf51DK, however whatever configuration I use it always outputs a value equivalent to ~0.6v input. I've tried with the basic ADC example...
I bought a product with NRF52840 as MCU. Now I want to communicate with other devices over RS485. So I had to make some changes. I have the following questions and hope to...
i try to build simple hello world program in c++. it successfully compile just yesterday, but somehow it fail to compile now. on the log it seem to use /usr/bin/c++ to compile...
The following code snippets produces Error code 0x0005 when trying to update a characteristic value via custom characteristic programming nd connected to nRFConnect app: ...
The nRF52833 datasheet lists a number of pads as "N.C." however I could not find anything in the datasheet about what to do with these pads. Is it safe to route traces over...
