Hi, It sounds like you should take a look at the BLE beacon example in SDK. This example advertises service data in broadcast mode, which means that sensor data can be read without connecting to the peripheral. I would also recommend experimenting with app. note 36 (link) if you're new to BLE. Note that the app. note is currently compatible with nrf51 SDK 5.2 only.
