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

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...
There are two USB ports. IMCU and nrf5340. I had a lot of trouble with bad cables but i found one that works and I find that I have a jlink drive that pops up so I know there...
Hi Sir
The npm1300 allows setting the default voltage using resistor values as shown in the table below. However, if I want to set the voltage to 1.05 V using resistors...
I am working on synchronizing RTC timers on several nrf52832s and i would like to have a single clock clocking all the RTCs on all the boards. I understand that the LFCLK...
I thought I had been extremely careful to _not_ brick the device, but apparently I did.
I created a firmware-dfu.zip file, even with appropriate keys, etc. as below.

We're developing a low-power application on the nRF9160 where we need the device to stay connected to the server over LTE, so we cannot enter System OFF mode. Instead, we...
Hello,
I am developing a product using the nRF54L15 and have noticed a discrepancy in the documentation regarding clock pins. My intention is to use pins 1.02 (SDA) & 1...
Describe Need to repeat disconnect/connect cycle after BT timeout. Problem is when using UART over BT with Nus Shell when connection is terminated by timeout (for example...

Hi, It's looks like I bricked my Thingy:91x . It was working fine when I program it with the target " thingy91x/nrf9151/ns " then later while learning I try program the in...
Hello,
I've got some questions regarding the use of DFU target library. I get my update data from the UART and like to use a setup with two partitions on my device. Is this...
Hello, I am new to android development. I am building an Ble App for some of my work in which I want to include Direct Firmware Upgrade(DFU) over-the-air.
I have building...
Previously, I designed a PCB for the nRF52832 chip using the RFANT3216120A5T antenna ( link ). However, I was only able to achieve a very limited Bluetooth range of around...
Hi Nordic teams :
I find that datasheet v0.8 (page12) shows that SDA do not need clock.
Page 277 still shows that SDA need clock pin.
Could you help to clarify which...
Hi, I previously wrote about an unexpected behaviour which I've made a diagram for below. It's relatively simple though, the COMP watches a voltage and fires a toggle event...
