For more information on what uplink messages (***mode-independent events***) and additional data from various sensors in the device (***appended payload***) can be sent regardless of mode and how to fine-tune message behavior (***alerts***), see *Mode-independent information and events.*

**Switching to mode, arming and disarming information:**
Follow the *Basic Operations With SimpleHw Devices guide*, where you can also find information about LED behavior, relevant Sigfox messages and more.
Here’s what’s important for **Temperature delta alert WiFi Atlas** messages:
* To set this mode, the downlink needs to include this mode register setting: **0143**
* The uplink messages need to begin with the mode hex as the first byte: **43**
* When arming the device, you should see this message: **4310**
* When the device is armed, it should send you these two bytes: **4311**
* If you disarm the device via long press, you should receive this message: **4314**
