I'm upgrading a project from SDK 15 to SDK 16. Previously in my gap parameters init I had this code
This works fine for seeing the peripheral and operating it as a UART...
I wasn't sure which product to put in. I am looking for a BLE discovery tool for EEG devices -- particularly the Muse 2 Headband. Which of Nordic's software should I use for...
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...
