 The Zephyr Project RTOSThe Zephyr Project RTOS is a recent effort by the Linux Foundation to provide the embedded world with a free, secure and fully-featured Real Time Operating System.It is designed from the ground up to be a modern, scalable, secure and responsive RTOS with a clear focus on IoT protocols and foundations.This open source RTOS is Apache 2.0 licensed and has a fully open development modelRecently Nordic contributed ports to all of our Cortex-M based ICs (nRF51, nRF52832...

It´s exciting to see that our friends at Sony Mobile Research and Incubation have released a desktop application called Otii, which supports our Power Profiler Kit.The beta version of the Otii application is cross platform and runs on Windows, Linux, and macOS. It is straight forward to install and use with the Power Profiler Kit connected through a regular USB cable. With Otii you get a nice tool for finding out what parts of your software that is the cause for certain power consumption related behavior...

I am using the nRF52840 Preview DK with BLE 5.0. In the BLE ATT_MTU Throughput Example,I use several api such as sd_ble_gatts_value_get and so on,but i still can not read the correct data. How can I read the payload data correctly with a correct api?...

Hello,I'm using several gpiote interrupts in SDK 12.0.1.I want to know the max number of low power input pins.My configuration in sdk_config.h is like below. thanks,// GPIOTE_ENABLED - nrf_drv_gpiote - GPIOTE peripheral driver//==========================================================#ifndef GPIOTE_ENABLED#define GPIOTE_ENABLED 1#endif#if GPIOTE_ENABLED// GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS - Number of lower power input pins #ifndef GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS#define GPIOTE_CONFIG_NUM_OF_LOW...

Hello,I am currently working on an ultra-low power project that requires reading an I2C accelerometer multiple times per second. After analyzing the current consumption in the design, it is clear that the TWI peripheral uses quite a bit of power. I was able to capture an oscilloscope screen capture that shows the peak current consumption at approximately 4.5mA (see attached image). It is important to note that I am measuring the voltage drop across a 10-Ohm resistor, therefore 44.89mV measured across the ...
