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...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi, We are using the heart rate example for developing our firmware, where we plan to send data out every 15 mins. But when we try to increase the advertisement interval beyond...
Hello Nordic Team,
Currently i'm trying to join my custom HID (a joystick) with the ble_app_hrs_rscs_relay example (SDK 16) for a personal project which consist in: a nrf52832...
Dear Nordic,
I am trying to create a simple interface between my PC with Windows and using PyUSB (since it is a simple wrapper, using libUSB as backend) and the nRF52840...
Hello,
We have an old working product which is developed in nRF5 SDK v11.0.0. We want to add nfc type 4 tag part in our product.
In SDK 11 there is only support for nfc...
I am looking to understand the state of a pin after calling nrfx_saadc_channel_uninit(channel);
Does it simply return to the last configuration state of the GPIO or something...
Hello, I am using a nRF51822 chip to communicate with a sensor. The sensor continuously outputs its reading via UART every couple of seconds. This is what I am currently doing...
Hi, I'm trying to migrate from the nRF9160 DK to our own board, and I'm having some trouble getting the west build system to play nicely. I've essentially started with the...
Hello everyone.
I have been working on a project that involves DSP and BLE on nRF52832.
The firmware needs to sample an accelerometer signal every 1ms with high accuracy...
Hello,
I am working on nRF9160dk. I have interfaced a GNSS sensor with nRF9160 using UART and receive the data continuously. When there is an interrupt, this data is send...
Hi All,
I have developed application which will detect key press and perform he respective task ,using the S132 (nrf52) with button-less dfu project (SDK15.3)which
includes...
Hi everyone
I have been facing some issue while allocating memory using nrf_malloc function on nrf52840.
I am giving a size parameter of 8 bytes inside the nrf_malloc...
Hi,
We are working on Nordic NFC antenna modification - it has to be lengthened by 15 mm to fit in our case.
1. Question - is the green marked part curved just to gain...
Dear community,
We are testing a nRf8001 Implementation, DTM transmitter Test with continuous unmodulated carrier.
In the PS 1.3 / 22.5 i saw that the dynamic data is...
Hi,
I'm trying to validate a device which uses VSP to communicate. It has a custom service with only 2 characteristics. 1 to Write (TX) and the other Notifies (RX).
When...
Hello :
I come from STM32 programming and I am new to Nordic device programming.
for nRF52840 DK, I am looking at the ble-blinking example and try to understand Softdevice...
