Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
hi
i'm new to the nRF platform and realised it uses zephyr. i come from a pic & stm32 background with little rtos knowledge and find the official zephyr cryptic. especially...
Hello,
according my Observation Zephyr, more precisely the rpmsg stuff for BLE between both nRF5340 cores, doesn't work when optimization is switched off. But stepping through...

hello nordic team I ran the ble_app_uart example in sdk 15.3.0 on nrf52832. When i add printf("\r\n%d\r\n",15); to the code as follows, the program prints 15 to the serial...
Hello.
We are developing using nrf52832 (S132 v7.0.1, SDK v17.0.0) as a peripheral.
I am creating a process to set the characteristic and send an indication using sd_ble_gatts_hvx...
Thank you very much for your help. I am currently working on implementing a PWM control function using the nrf52840. I would like to ask you about a build error that occurred...
Hello All, I am trying to figure out how to use the PWM.h driver for the nRF9160 to read an input pwm signals pulse width and period (im currently working with the nRF9160...
I need to know in which case the SIW_DET pin is used. Does it depend on the version of the nRF9160 ? Then which versions ?
And is this detection function better in software...
Hello, guys!
I am using nRF51822 SoC with Zephyr. There is a need to configure multiple GPIOs as inputs, with the possibility to fire an interrupt on rising/falling/both...
Hi There,
I am working on a project based on nrf51822. I need to establish pairing the device with smart phone by clicking a button as confirmation on the nrf51822.

Hello,
I already fully understand how nRF5340: Network core bootloader working.
As I wondered in the title, I want to move the application firmware data of network core...
The project uses nRF5340. A signal is connected to P0.27/AIN6, and during "normal" mode the pin is used as an ADC.
Before going into sleep mode we would need this pin to...
Hello,
