What happens when battery or temp sense is set to a zero value (Legacy Firmware)?

With the Legacy BT510 firmware, when the Temperature Sense Interval is set to 0, with the Sentrius BT510 App, the temperature measurements are stopped, although there will be 1 one more measurement when the value is changed.

When the Battery Sense Interval is set to 0, with the Sentrius BT510 App, battery measurements are stopped. Note there is a power fail circuit built into the device that constantly monitors the battery level. Even if the Battery Sense Interval is set to 0, and the battery level drops below the failure level, a battery fail event will still be advertised.
