Hello,
I’m working on a Zephyr-based application using the nRF5340 where I need to optimize power consumption. The intended behavior is:
The device should stay in...
According to the nRF52832 Product Specification, “A step increase in supply voltage of 300 mV or more, with rise time of 300 ms or less, within the valid supply range, may...

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
I need a BLE device that can broadcast codes/id to my android mobile app. Also, I need those codes be changed by once in a while by an admin app. Is this possible?
I'm unable to get any output when writing to the UART while using the s110 softdevice. I'm refering to the hardware UART. I'm not using bluetooth for serial.
I'm using...
Hello,
I wrote a firmware for my project, based on the UART over BLE example, so using the softdevice, establishing connections, etc. It works.
I'd now like to use a...
Hi all,
I can program and debug my application just fine when the softdevice is not used (initialized). Problem is, when I do use the softdevice, I end up in Hard Fauld...
Hello,
In our prototype (Embedded System) we want to use nRTF24AP2 with Chip Antenna, as W3006, for example.
Our questions are: where and how needs to be placed the Chip...
Hi there,
I currently have an nRF51 DK set up transmitting six 20 byte packets per 7.5ms, there about, to an nRF51 Dongle set up as a central. When viewing with Master...
Hello,
I would like to move on from using nrf_delay_ms().
I thought this would give me some first results, but It don't. Whats wrong?

Should be noted that i'm using nRF51822 breakout board and i have a lot of problems with its programming. And i'd just begun to write own topic about my problems with connection...
Hi,
I am playing around with the BLE_proximity_template on the Redbearlab BLE shield and an Arduino Uno. I uploaded the sketch and paired my Android Lollipop device with...
I'm a beginner and have been using library provided by the nordic to communcate with nrf8001. I read nrf8001 data sheet but couldn't understand how to use the aci commands...
Hi,
I want to get this dongle to 'see' the data being transmitted to and from the nrf51 dk. I saw a note here adafruit saying
The sniffer firmware cannot be used...
Hi,
i wuold like to control one port of my home gate's centraline by Ble shield on Arduino.
I need to send an impulse for 1'', no more. Like a release button, not like a...
Got it working .. forgot (didn't know) I had to change the attribute length as well
I am currently trying to figure out where/how to attach my measurements so they can...
We've been using the nRF51822 sniffer to listen to packets. One of our developers used to be able to use it decrypting packets without a problem (He uses 32-bit system, firmware...
