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...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {

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, At the moment I am using nRF Toolbox to upload DFU *.zip files to our devices. We have been finding that the devices will become unresponsive after a firmware upload,...
Hi!
I have trouble in flashing a simple nrf51822 via the nrf51-dk.
Can anyone ensure me that this simple wiring should be able to upload an hex file onto the nrf51822...
The Peer Manager is currently in experimental state and is not recommended for production and same for the device manager for some sdk.So which SDK should be preferred
Hi,
Im using S130softdevice.i wanna make dimmer by using experimental_ble_app_blinky project on gpioet
But i have a problem with detecting 10 milisecond time (it means...
Hi,
I am new starter in Nordic platform. I am using device nRF51822-CFAC, the SoftDevice is S130_nRF51_2.0.1(Id: 0x0087).
What I am doing is to put NRF51 into system...
Hi,
I'am tring to test the dfu by secure bootloader.I had done all steps like: Test the BLE Secure DFU Bootloader application by performing the following steps .But I found...
I am implementing an SPI master to communicate with an accelerometer using the SPI HAL directly. My chip is marked nrf51822QFACA11609AC. I have implemented blocking functions...
Hi,
When the UART is configured to use FIFO , i use the UNUSED_VARIABLE(app_uart_get(rxdata));
to read a buffer from FIFO.
how can i also receive a number of bytes...
Hi,
I want to do this cycle with GPIO without interrupting it on NRF51 with BLE softdevice:
PIN1 to HIGH level
read value of PIN2
PIN1 to LOW level
Repeat...
Hello, I'd like to do directed avertising to a central which has a random private resolvable address. My idea: both devices share a pre-defined IRK so the peripheral can compute...
I tried, but it does not work.
for(int y=0;y<100000;y++)
{
if(nrf_uart_event_check(NRF_UART0, NRF_UART_EVENT_TXDRDY))
{
nrf_uart_event_clear(NRF_UART0, NRF_UART_EVENT_TXDRDY...
Hi,
We have a little issue that we at the moment need to cycle power on v3 nRF51822 after DFU.
We have determined the the reason has something to do with the whole complicated...
