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 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart" ;

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
I'm using the Eval Kit PCA 10001 V2.1.0 and Nexus 5 with new Android version 4.4.2. Connecting to the Eval Kit works just fine, but when i perform a service discovery...
I have an nRF51822-based peripheral using the SoftDevice 110 v7.0.0 and SDK v6.0.0. The peripheral uses two custom characteristics under a single custom service. I'm using...
Hi
I'm using sd_app_evt_wait(); to go into low_power mode.
For some reason it comes back immediately, but I can't figure out why.
If I call it a second time it stays...
Hi,
I'm trying to flash the S110 onto my nrf51822 SoC, but nRFgo gives me the following error. (Also, hitting recover just gives me an error: "an error condition was detected...
Within app_button module, code for app_button_is_pushed() seems to have changed from SDK version 5.1 to 6.0. I notice my code has stopped working properly with that update...
Hi
Now, we are planning to implement an ANT+ RX (slave). I checked nRF51422 product spec. Radio current consumption is 12~13mA if receiving data between 250kbps and 2Mbps...
I'm using the boot loader that comes with the beacon development kit and I want to change it so that when the application software is running it can restart the device in...
I have managed to get the SPIS block working using standard sets of read and transmit buffers. This all works.
I am now trying to use the ORC register to send a single...
I am wondering how you put the nrf51822 chip to sleep. I've determined that the way to do this with the soft device is sd_app_event_wait() in the while loop. What about non...
Hello
I've been trying to create a simple BLE observer that outputs the nearby devices data onto the serial port using a PCA10001 board.
For this, I'm adapting the code...
Hi - I'm using the 51422 dfu bootloader from the nrf 6.0.0 SDK and it works fine with the iOS apps, I can send both .bin and .hex files to the device and it works fine. However...
Hi,
I am using nRF51822 evaluation kit. I want to develop GPIO isr (GPIOTE_IRQHandler) which can handle multiple GPIO interrupts. I have tried to enable the GPIOTE_IRQHandler...
Hi!
When using bootloader, I cannot update application data from Keil (for example for debuging), because after restarting bootloader is loaded and
