# Programming Your Radio (Advanced)

### REST API

A RESTful API interface is included to place the radio in "Team Bridge" or "Team Access Point" mode. 

#### Configuring as an Indoor Client/STA (TEAM\_ROBOT\_RADIO)

```
curl -XPOST http://192.168.69.1/configuration -d '{"mode":"TEAM_ROBOT_RADIO", "teamNumber":1538,"wpaKey6":"SeCuRe-6Ghz-Key","wpaKey24":"My-2.4Ghz-Key"}'
```

{% endcode %}

By placing the radio into "Robot Radio" or "TEAM\_ROBOT\_RADIO" mode, the radio will be configured to connect to an 802.11ax Wi-Fi 6E access point with the corresponding SSID of the team number listed. 

| JSON Key   | Description                                    | Value                                   |
| ---------- | ---------------------------------------------- | --------------------------------------- |
| mode       | Sets mode to Client/STA (robot radio)          | "TEAM\_ROBOT\_RADIO"                    |
| teamNumber | FRC team number                                | Decimal                                 |
| wpaKey6    | SAE password for the 6GHz Wi-Fi connection     | String between 8 and 16 characters long |
| wpaKey24   | SAE password for the 2.4GHz Wi-Fi access point | String between 8 and 16 characters long |

{% hint style="info" %}
When DIP switch #3 is in the ON position AND a valid connection to an 6GHz 802.11ax Wi-Fi access point is not present, the radio will simultaneously broadcast as a 2.4GHz 802.11ax Wi-Fi access point with the SSID of "FRC-XXYY" where XXYY is the programmed team number.

Once the radio successfully connects to a 6GHz 802.11ax Wi-Fi access point, the 2.4Ghz 802.11ax Wi-Fi access point will shut down until the device is power cycled.
{% endhint %}

#### Configuring as an Access Point (TEAM\_ACCESS\_POINT)

{% hint style="danger" %}
When configured as a **WIRELESS ACCESS POINT**, due to regulatory requirements, the VH-109 radio **cannot be powered using a battery source** and is for **Indoor Use Only**. The device is regulated by the **FCC** **LPI** (Low Power Indoor) requirements when in this mode. \
\
Only when the VH-109 radio is configured as an **INDOOR CLIENT DEVICE (STA)** may it be powered using a battery.

By placing the radio into Access Point or "TEAM\_ACCESS\_POINT" mode, the radio will be configured to broadcast as an 802.11ax Wi-Fi 6E access point with the corresponding SSID of the team number listed using the SAE key provided.
