# Upgrading Firmware

## Overview

This page will discuss how to upgrade the firmware on your robot radio.

## Instructions

{% stepper %}
{% step %}

### Download The Latest Firmware

Before you begin, download a copy of the[ latest firmware](/overview/firmware-releases.md) to your computer. 
{% endstep %}

{% 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](/overview/programming-your-radio-at-home/network-assistant-tool.md) 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 The Radio's Configuration Page

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

| Wired                                      | `http://192.168.69.1/` |
| ------------------------------------------ | ---------------------- |
| Wireless (DHCP) Factory Default            | `http://10.0.1.1/`     |
| Wireless (DHCP) Team Number Previously Set | `http://10.XX.YY.1/`   |

{% 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/`
{% endhint %}
{% endstep %}

{% step %}

### Select Firmware File

<figure><img src="/files/3IPsgqJFW8rdfxrnmbdb" alt=""><figcaption></figcaption></figure>

Select the firmware file from your computer.&#x20;
{% endstep %}

{% step %}

### Enter Checksum

Enter the checksum located on the [firmware release](/overview/firmware-releases.md) page for the corresponding version you're upgrading to.&#x20;
{% endstep %}

{% step %}

### Click Upload

When you're ready to start the upgrade process, click upload.
{% endstep %}

{% step %}

### Wait Until Finished

The upgrade process should take about 2-3 minutes to complete. **DO NOT power cycle the radio while it's upgrading.**

Wait for the upgrade process to finish. You can tell the upgrade is complete when the **PWR light** is solid and the **SYS light** is slowly blinking at 1 Hz.
