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...
Hi,
We are having issues with this part bridging on our via-in-pads. We are using 2oz finished outer layer copper.
Do you have any footprint recommendations for 2oz copper...
Hello,
I'm looking for guidance and understanding of how to properly use the KMU and ITS for secure key storage of a key generated on device.
I see that typical ITS use...
Hi all,
Actually I'm building with vscode my firmware for a custom board build with an nRF9151 non secure. After building I got a merged.hex file, this is the file upload...
In the reference designs, the inductors in the antenna circuit are simply referred to as "High frequency chip inductors". Do you have any example manufacturers part numbers...
I'm testing my nRF51822 Bluetooth Smart Beacon Kit (pca20006). I've successfully uploaded ble_app_beacon_bcs code example to my beacon via Master Control Panel Android app...

Hi All,
I tried to use the nRF51422 device UART RXTO events using nrf51 SDK v6.1.
I set the NRF_UART0->INTENSET in app_uart_init() as following:
// Enable UART interrupt...
Hi, I have just managed to successfully read ADC values and send as a service but they are in uint8 format. Is there an easy way to convert this to decimal within my adc handler...
Is there provision for a serialization application processor to control GPIO on a nRF51822 used in serial connectivity mode? Can the nRF51822 be used as an I/O expander?
Hi,
I want to simultaneously read the value from 3 analog pins. For this, do I create just one adc_init function and handler functions or do I need to create multiple initializing...
Connections to my peripheral device are generally very short. I don't really need to have my device request a connection parameters update.
Does this mean that I can safely...
I purchased a pair of FTDI cables, and I can't seem to get them to work.
Unsure if the pinout is standard but here is the mapping of the cables provided:
Red wire： 5V...
I am using the N548 with the S310 soft device. I have set up the device for asynchronous communication via the UART. I can send ANT+ commands via the UART and I get valid...
Hi there,
I am quite new to BLE.
I am about to buy a nRF51822 Bluetooth Smart Beacon Kit. But before that I would like to be sure if I am able to advertise battery level...
Hi,
We just recently received our (custom) board with the nrf51822.
To program and debug the nRF I use the pca10028 and the debug out header.
I wrote a very basic program...
I tried loading SoftDevice, Bootloader, and Application using the SoftDevice and Precompiled hex files that come from the example code version v1.1.0. I am using nRFgo Studio...
While attempting to update the firmware from a HEX file, the DFU Application in the nRF Toolkit reports that the upload failed with an unknown error 22. I was sniffing the...
I have a bootloader running on my NRF51822. It uses a relocated vector map in RAM and jumps to function.
I therefore have two debug files and source code sets.
Does...
