The
Sentrius™ BT510 doesn’t have a power switch. It is shipped with an installed battery and is in a low power state called shelf
mode.
To wake the device, firmly press the button in the center of the round face for at least three seconds until the green LED turns
on.
When you release the button, the green LED blinks once a second.
The sensor is in sleep mode from the factory. Pressing the button for three seconds wakes the sensor and it starts to advertise.
The sensor is now ready for normal operation configuration. This can be done using a phone or gateway. The LED blinks for 30
seconds or until a connection is made, the button is pressed again, or the sensor stops advertising. The default state of the
sensor is to advertise indefinitely.
Quickly press the button to perform a battery good check. If the battery is good, the sensor briefly blinks the green LED and
starts to advertise. If the battery is below the recommend operating voltage, then the LED does not blink but the sensor tries to
advertise.
If the button is held for more than ten seconds and released, the sensor performs a factory reset. A factory reset erases all logs,
pairing information, and reset the configuration to its default state.
When the button as shown in Figure 1 is held for 10 seconds, the LED turns yellow or red. If the LED turns red, then factory
reset is not allowed using the button. This is because the sensor is locked. The sensor can be locked by using one of the JSON
properties. When locked, the factory reset can still be performed using Bluetooth. If the LED turns yellowish orange, then factory
reset is allowed. The yellowish orange LED blinks when the button is released.
The battery is a 3-volt lithium of CR2477 type.
Note: The battery door cover has a gasket inside to keep out liquids.
The sensor can be cleaned with a mild, non-abrasive detergent. Because it is not waterproof, do not immerse it in water.
The sensor does not require any calibration.
