Dear DevZone,
While reviewing the implementation of x509_crt_verify_chain() in C:\ncs\v2.9.1\modules\crypto\mbedtls\library\x509_crt.c , I noticed that certificate expiration...
hello everyone ...I am working on a project that uses the nRF52840 IC. I would like to implement a power-down mode to reduce power consumption. In my project, I am using BLE...
Hello,
I'm working on developing a driver for the AD4130 ADC in Zephyr and I'm facing issues related to the device tree binding integration. Specifically, it seems the chain...
Hi support
We are considering connecting eMMC 5.1 ( FLEXXON eMMC 5.1 MLC (XTRA III 100ball). SPEC V1.4 (2).pdf ) to an nrf5340 device.
I understand that Zephyr 3.3.0 includes...
Hi support
I am developing code for the application core on the nrf5340 and testing this on an nrf7002dk dev kit. I am using sdk version 3.0.0. The code needs to read from...
I am using nrf52832 IC on my PCB with sparkfun antenna trace connected to it. It was working fine on one of my PCB then I changed the profile of PCB by retaining the same...
Hello,
First of all, I've read the entry below.

My questions:
1 - If I cannot advertise for only specific masters, how can I provide...
Hello!
I have a problem with NRF8001 modules. I have two similar boards - one with NRF8001C and another with NRF8001D module. NRF8001C board works well, but NRF8001D board...
Hello all, at present time I'm making investigation of BLE link stablility at harsh megapolis environment and at long open space ranges. During testing I found out some information...
Looks like there is an error in the nrf_drv_gpiote_common.h :
#define INTERRUPT_PRIORITY_VALIDATION(pri) STATIC_ASSERT(((pri > 2) && (pri < 4)) || ((pri > 5) && (pri <...
Hi guys,
So as I'm migrating from SDK10 to SDK12 I've noted that the app_pwm module is consuming more power then expected while disabled ~300uA. After initialization, I...
Platform: nRF52-DK using SDK12.1.0 and S132
Summary: Using nrf_log module from SDK along with RTT by setting NRF_LOG_BACKEND_SERIAL_USES_RTT flag causes nrf_log_serial...
For example, in SDK11, the file:
components/softdevice/s130/toolchain/armgcc/armgcc_s130_nrf51822_xxaa.ld
Contains:
RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x4000...
Not a question, but a big thank you to Nordic Tech Support (Kristin) who reviewed our nRF24 design several times until we got it right :)
Implementing the recommendations...
Hi,
I am creating the first prototype for my BLE product and for now I used the suggested layout from the datasheet, but I am kind suspicious of that layout it seems very...
I follow the example, as below
nRF5_SDK_12.1.0_0d23e2a\examples\peripheral\flashwrite
but I only get some error, can not get anything, and the ble is unconnected.
Hi there. I'm making a sensor system which is intended to measure an ADC value, and send it using the Heart Rate Sensor template. To make this, I've rebuilt the ble_app_hrs...
Hi
Does the newly released nRF52840 chip have pins on the side, corresponding to the "outer ring" (A8-23, AD2-23, B1-W1, ...) pins on the underside of the chip, like this...
hello i am interfacing i2c sensor mma8452 with nrf51 dk. my function is
void mma_read(uint8_t *x, uint8_t *y, uint8_t *z)
{
uint32_t err_code;
uint8_t rx_buffer...
I have to sample 3 differential channels periodically. Should I calibrate SAADC for each channel individually? Unfortunately, "nRF52832 - Product Specification v1.0" doesn...
