Just reset V3 sensor on the Edge 1030 and two sensors were recognised, the BLE and ANT+ which one should I use? And can I use both and under what circumstances.
ANT+ You don't get cycling dynamics through Bluetooth... yet However you can use Bluetooth with, say, and Apple TV while using Zwift and ant+ for your head unit. It is also good to know that Bluetooth only allows one Bluetooth connection at a time.
