# Setting VH-109 To Access Point Mode

## Overview

This page will discuss how to program your VH-109 Robot Radio to act as an access point. This will allow you to test and practice driving with a single robot.

## Instructions

{% step %}

### Configure Your Computer

There are two options to configure your computer:

{% tabs %}
{% tab title="DHCP" %}
If the configuring computer has it's network interface configured to obtain an IP address via DHCP, the computer will be able to reach the VH-109 device at `10.XX.YY.1` (Client/STA mode) or `10.XX.YY.4` (AP mode). 

VH-109's programmed at the factory are configured to team #1 in Client/STA mode, setting the IP address to `10.0.1.1`.
{% endtab %}

{% tab title="Network Assistant Tool" %}
The [Network Assistant Tool](https://frc-radio.vivid-hosting.net/overview/programming-your-radio-at-home/network-assistant-tool) is a custom tool developed by Vivid-Hosting to configure your computer to connect to your VH-109 radio. 

Use the instructions on the Network Assistant Tool page to set a static IP address on your computer, then proceed to Step 2.
{% endtab %}

{% tab title="Manually Assign Static IP" %}
The VH-109 device is also pre-programmed with a failsafe/management IP address in the `192.168.69.0/24` subnet to reach the management IP of the VH-109 radio.\
\
For example, the network interface on your driver station laptop can be temporarily configured to:

| IP Address    | `192.168.69.2`                |
| ------------- | ----------------------------- |
| Subnet Mask   | `255.255.255.0`               |
| Gateway       | `Leave Blank`                 |
| DNS           | `192.168.69.1 or Leave Blank` |
| {% endtab %}  |                               |
| {% endtabs %} |                               |
| {% endstep %} |                               |

{% step %}

### Connect To Your Radio

Create a wired or wireless connection between the computer and the radio.
{% endstep %}

{% step %}

### Navigate To Radio Configuration Page

Depending on the type of connection, this can be reached one of three ways:

<table data-header-hidden><thead><tr><th width="334"></th><th></th></tr></thead><tbody><tr><td>Wired</td><td><code>http://192.168.69.1/</code></td></tr><tr><td>Wireless (DHCP) Factory Default</td><td><code>http://10.0.1.1/</code></td></tr><tr><td>Wireless (DHCP) Team Number Previously Set</td><td><code>http://10.XX.YY.1/</code></td></tr></tbody></table>

{% hint style="info" %}
Radios running firmware >1.1.0 (released 02/04/2024) include an mDNS responder. The radio can also be reached at `http://radio.local/`

| Field                               | Description                                                                          |
| ----------------------------------- | ------------------------------------------------------------------------------------ |
| **Access Point Mode**               | This means the device will act like an access point for a radio to connect to.       |
| **Enable 2.4 GHz Wi-Fi**            | This this enables the 2.4 GHz radio for diagnostic/limited driver station connection |
| **Enable SystemCore Mode**          | This changes the default DHCP reservation for roboRIO-XXYY-FRC to robot.local        |
| **Team Number**                     | Your team's FRC team number                                                          |
| **SSID Suffix**                     | A suffix that is appended to the end of the SSID. Ex: "1538-coolbot"                 |
| **WPA Key For 6GHz Connection**     | The key for 6GHz connection                                                          |
| **WPA Key For 2.4GHz Access Point** | The key for 2.4GHz connection                                                        |
| **Wi-Fi Channel**                   | This is the Wi-Fi 6E channel the access point will broadcast on                      |
| {% endstep %}                       |                                                                                      |

### Click Configure

Once you've configured the device, click configure to save it to the radio.
