# What should you see on the Sigfox Backend

## Downlink

1\. Uplink message with the current mode as the first byte and 0x81 as the second byte (Extra long press). Following bytes are FW and HW revisions:\
For example: **018106010A3536**

|   MODE   |             EVENT             | API ver. | FW ver. | FW ver. |    HW    |    HW    |
| :------: | :---------------------------: | :------: | :-----: | :-----: | :------: | :------: |
|    01    |               81              |    06    |    01   |    0A   |    35    |    36    |
| Press me | <p>Extra long</p><p>press</p> |    6.    |    1.   |    10   | Internal | Internal |

2\. You should see ACKED when you click on the downlink arrow - this means that the BTS sent the downlink to the device (which does NOT mean that the device received the downlink!)

3\. From FW version 6.0.228 and newer you will see a downlink confirmation uplink message. The first byte will be the new mode (if you’ve changed modes) and the second byte will be either 0x15 or 0x16\
For example: 0116

|   MODE   |                EVENT                |
| :------: | :---------------------------------: |
|    01    |                  16                 |
| Press me | Downlink configuration confirmation |

{% hint style="warning" %}
If you want to see this confirmation message in the FW version 6.0.227 or older, change the value of register **0x0F** to **0x0E**
{% endhint %}

## Arming

1\. Uplink message with the current mode as the first byte and 0x10 as the second byte (Start of arming).\
For example: 0210

|   MODE   |      EVENT      |
| :------: | :-------------: |
|    02    |        10       |
| Guard me | Start of Arming |

2\. Uplink message with the current mode as the first byte and 0x11 as the second byte (Armed).\
For example: 0211

|   MODE   |      EVENT      |
| :------: | :-------------: |
|    02    |        11       |
| Guard me | Armed/Activated |

## Disarming

Uplink message with the current mode as the first byte and 0x14 as the second byte (Disarmed)\
