# BTiny Mission sensor usage

Use this flow to start, run, and stop a transport mission with a BTiny mission sensor.

{% stepper %}
{% step %}

### Start the mission

Start the mission using one of these methods:

* **Boomerang** (PC or smartphone). Choose an immediate start or a scheduled start.
* **BTINY009 tactile button**. Press it while the sensor is within wireless range of a **Cloud Connector**.
  {% endstep %}

{% step %}

### Ship the package

Put the temperature logger in the package and ship it.

The sensor logs temperature offline. If it is within wireless range of a Cloud Connector, data is uploaded online to Boomerang.
{% endstep %}

{% step %}

### Stop the mission

Stop the mission using the same method you used to start it.

If the mission is scheduled, it stops automatically at the configured stop time. You can also stop it manually in Boomerang.

To stop it using the BTINY009 button, the sensor must be within wireless range of a Cloud Connector.
{% endstep %}

{% step %}

### Sync the data

Bring the sensor within range of a Cloud Connector. This ensures all logged data is transmitted to Boomerang.

After upload, the data is stored as a mission in a **real mission measuring point**.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
If the sensor is out of range during transport, it keeps logging. Upload happens when it later comes back within range of a Cloud Connector.
{% endhint %}
