https://devzone.nordicsemi.com/f/nordic-q-a/44494/nrf5-sdk-15-3-0-on-pca10040---hrs-demo-for-s332-hangingHi, I&#39;ve just downloaded SDK 15.3 and compiled BLE peripheral HRS app. After flashing SD 332 and the app and starting it, it seems to hang on disconnection. I.e. It starts fast advertising, I connect with Nordic nRF Toolbox and I receive data.
