MKR 1010 reading sensor data and send via BLE

I updated the libraries and firmware on a MKR 1010 to the nightlys version as of today.

I uploaded the example BLE LED sketch to turn on/off the LED using a terminal app on my phone and it works perfectly.

I have a sketch that reads temp data from three DS18B20 sensors and updates a small lcd display.

Each sensor could be a characteristic, and the MKR will read the sensors every x-seconds, and send the data over BLE in human-readable form via BLE.

But can't seem to get my head around the library.

Any help here?
