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...
Hi all,
I want to use nRF51822 (s110) to measure the frequency (0 to 5kHz) of a signal connected to an analog input. Other posts ( like this ) show that a good way to implement...
Hi,
SDK:8.1.0
Chip:nrf51822
Power Mode:LDO
Battery:CR2450
Application:beacon
The equipment static power consumption is 3.3 ua, after a period of time is 1.9 ma,but...
I'm using Keil5 to compile example of SDK v12.2. And I'm trying to understand each of Source code to understand how each of it is consists of.
I opened an example "SDK...
My code hit weak handler when I try to modify the examples/peripheral/saadc to run with softdevice s140 on nrf82840 PDK. All I did was adding a BLE Stack initialization before...
On the nRF52832, what is the longest period of time that the softdevice will control the CPU while doing things with Bluetooth? This is effectively the interrupt latency time...
I am working on nRF51 and nRF52 series SoC.
I need to check whether my radio device is connected or not and also to test radio functionality(like radio range, sensitivity...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
Is it the only way to call a function on a read characteristic to make a read request and then inside on_ble_event call the function?
Is this the right way?
Hi
in the communication with an SPI peripheral device, a communication cycle might take up to 5 ms.
It is implemented as a blocking function, meaning that app_sched_execute...
Hi all! Several weeks I've tryed to implement code for my wireless temperature sensor based on nrf24le1 and ds18b20. In datasheet said that in memory retention mode the power...
Hi,
Is it possible to send a advertisements for a single (or a fixed number of) Advertising Events? I need to control the number of Advertising Events "sent" for a mesh...
Hi, I'm looking to build a simple ANT+ application. My only asset for this project is a background in C/C++. I'll need to learn/relearn the basic electronics and protocol...
Hi Nordic,
I have an application that perfectly runs in the nrf51DK but that does not work in my custom board. In my custom board everything else works (i2c, leds lighting...
I understand that in order to trigger bonding procedure you need to read/write a secure characteristic.
I am using the nRF Connect application on IPhone and trying to see...
Hi all,
I need to take samples of a period of two periodic signals and made some DSP processing with both signals.
I need at least 64 to 128 samples per signals.
I...
