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...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
So im basing my project on your Android-nRF-UART-master example found in github, i don't know if its a app bug or issue regarding the circuit, but first connection is always...
I just started using the RTT and it's been a huge help. I'm working on a multilink application, and would like to have each link output to a different RTT terminal. I use...
Hi !
I'm using S130 softdevice on SDK 11 as central. I'm wondering if there are any conflits in the stack I should be warned. I know it is not allowed to start connection...

Hi,
I'm starting to work on nRF52 with eclipse (on Ubuntu). I use this tutorial to configure everything : devzone.nordicsemi.com/.../
Everything looks good but when I try...
Hello,
I am having difficulty having two nRF24L01P's communicate with one another.
I have set up the devices in what I thought was a minimal system.
I will appreciate...
What is the switching frequency of the DC/DC regulator in the nRF52832? The DC/DC is great for reducing power consumption, but I am worried about the switching noise getting...
Hello.
I am trying to save i/o lines on an 8-pin PIC, and planning to run an nRF24L01P with its CE pin tied to VDD. I am willing to power-down to get out of the RX mode...
Hi
I am using an Identive NFC reader/writer SCL3711 and their sample app to read tags.
In the sample app, through the debugger I can see that it is registering an NDEF...
hello, Nrf24LU (Rx) , nRF51822(Tx).
The Nrf24LU Can only receive one packet。
if I use this function twice , like this:
The Nrf24LU can receive Continuous.

Hi,
I use nrf51422 and integrated BMA250E for Pedometer,
Now I can count the step but I dont how to calculate the speed, cadence and stride length like below
static void...
Hi All,
From my firmware I need to send large ble packets say of 1 K to the phone.
Is there any library or example code for sending large packets. Currently I am splitting...
Hi,
Our application requires that we connect a nRF52832 to a Microchip PIC32MZ host via the Nordic parts UART (RS-232 at CMOS levels).
In a previous application, we...
Hi everyone,
I've been testing SPIM with easyDMA, using nrf_drv_spi. I'd like to flush a 6-axis sensor FIFO in one SPI operation (31 samples * 12 bytes = 372 bytes) but...
