Hi,
In our project, we are using a small RTOS to switch between simple tasks and set MPU. We would like to run all task in unprivileged mode, but some Nordic SDK libraries...
Hi everyone,
I have written a code that sends data over BLE notifications (IMU data). It works great so far and now I want to read the analog values from eight force sensors...
Hi everyone,
I have a problem I can't sort out. My program runs fine indefinitely if I set one variable in a function at one point but if I don't do that, the program, or...

Hello,
I need to develop two applications for nRF51822 using SES version 4.18 (macOS). One is a DFU bootloader. The other is an application based on the ble_app_uart (ble_peripheral...
Hello,
I am trying to run the BLE Thread Dynamic Template example on a nRF52840 dongle. I'm using Segger Embedded Studio to generate an hex file. I flash the hex file to...
Hello,
During testing we found that whenever in system off mode, the CPU wakes from VBUS rising. As expected. We then do a vibration to notify the user the USB cable was...
When integrating nRF Mesh SDK 4.1 with nRF SDK 16 I got an error in runtime.
The call sequence:
