# 🏎 F1 2021 UDP Telemetry Client and App 🏎 (🚧 Under Progress 🚧)

![Awesome](https://cdn.rawgit.com/sindresorhus/awesome/d7305f38d29fed78fa85652e3a63e154dd8e8829/media/badge.svg)

![F1 logo game 2021 Codemasters](https://raw.githubusercontent.com/mrcodedev/f1-2021-telemetry-app/main/img/logo.jpeg)

This is a TypeScript UDP client, telemetry parser, and app for Codemaster F1 2021 videogame.

The F1 series of games support the outputting of key game data via a UDP data stream. This data can be interpreted by external apps or connected peripherals for a range of different uses, including providing additional telemetry information, customised HUD displays, motion platform hardware support or providing force feedback data for custom steering wheels.

In this repo, can show the data in app do it with powerful StencilJS. Can show the data in a webpage and you can use it to do a plugin of Twitch.

## Installing

```bash
npm i
```

## Usage

In the game, you must activate UDP Telemetry, with your IP:

![F1 2021 UDP Options](https://raw.githubusercontent.com/mrcodedev/f1-2021-telemetry-app/main/img/udp-options.jpeg)

Use local direction IP, not activate retransmition UDP mode, consumes a lot of resources.

When you have UDP telemetry activated in the F1 2021 game, we can start the WebSocket Server.

```bash
npm run start:ws
```

After this we must start the F1 UDP clients, and WebSocket

```bash
npm run start:client
```

Or execute Server, Clients and App:

```bash
npm run start:all
```

You can now see the information that the game gives you.

### Overview

The F1 series of games support the output of certain game data across UDP connections. This data can be used supply race information to external applications, or to drive certain hardware (e.g. motion platforms, force feedback steering wheels and LED devices).

The following information summarise these data structures so that developers of supporting hardware or software can configure these to work correctly with the F1 game.

> Note: To ensure that you are using the latest specification for this game, please check our official forum page [here](https://forums.codemasters.com/topic/80231-f1-2021-udp-specification/).

If you cannot find the information that you require then please contact the team via the official Codemasters forum thread listed above, or raise a bug report through the F1 2021 forum, and a member of the team will respond to your query as soon as possible.

### Packet Information

### Packet Types

Each packet can now carry different types of data rather than having one packet which contains everything. A header has been added to each packet as well so that versioning can be tracked and it will be easier for applications to check they are interpreting the incoming data in the correct way. Please note that all values are encoded using Little Endian format. All data is packed.

The following data types are used in the structures:

| Type   | Description             |
| ------ | ----------------------- |
| uint8  | Unsigned 8-bit integer  |
| int8   | Signed 8-bit integer    |
| uint16 | Unsigned 16-bit integer |
| int16  | Signed 16-bit integer   |
| uint32 | Unsigned 32-bit integer |
| float  | Floating point (32-bit) |
| uint64 | Unsigned 64-bit integer |

### Packet Header

Each packet has the following header:

```c#
struct PacketHeader
{
    uint16    m_packetFormat;            // 2021
    uint8     m_gameMajorVersion;        // Game major version - "X.00"
    uint8     m_gameMinorVersion;        // Game minor version - "1.XX"
    uint8     m_packetVersion;           // Version of this packet type,
                                         // all start from 1
    uint8     m_packetId;                // Identifier for the packet type,
                                         // see below
    uint64    m_sessionUID;              // Unique identifier for the session
    float     m_sessionTime;             // Session timestamp
    uint32    m_frameIdentifier;         // Identifier for the frame the data
                                         // was retrieved on
    uint8     m_playerCarIndex;          // Index of player's car in the array
    uint8     m_secondaryPlayerCarIndex; // Index of secondary player's car in
                                         // the array (split-screen)
                                         // 255 if no second player
};

```

### Packet IDs

The packets IDs are as follows:

| Packet Name          | Value | Description                                                                      |
| -------------------- | ----- | -------------------------------------------------------------------------------- |
| Motion               | 0     | Contains all motion data for player’s car – only sent while player is in control |
| Session              | 1     | Data about the session – track, time left                                        |
| Lap Data             | 2     | Data about all the lap times of cars in the session                              |
| Event                | 3     | Various notable events that happen during a session                              |
| Participants         | 4     | List of participants in the session, mostly relevant for multiplayer             |

### Motion Packet

The motion packet gives physics data for all the cars being driven. There is additional data for the car being driven with the goal of being able to drive a motion platform setup.
N.B. For the normalised vectors below, to convert to float values divide by 32767.0f – 16-bit signed values are used to pack the data and on the assumption that direction values are always between -1.0f and 1.0f.

### Participants Packet

This is a list of participants in the race. If the vehicle is controlled by AI, then the name will be the driver name. If this is a multiplayer game, the names will be the Steam Id on PC, or the LAN name if appropriate.

N.B. on Xbox One, the names will always be the driver name, on PS4 the name will be the LAN name if playing a LAN game, otherwise it will be the driver name.

The array should be indexed by vehicle index.

### Session History Packet

This packet contains lap times and tyre usage for the session. This packet works slightly differently to other packets. To reduce CPU and bandwidth, each packet relates to a specific vehicle and is sent every 1/20 s, and the vehicle being sent is cycled through. Therefore in a 20 car race you should receive an update for each vehicle at least once per second.

Note that at the end of the race, after the final classification packet has been sent, a final bulk update of all the session histories for the vehicles in that session will be sent.

Frequency: 20 per second but cycling through cars

### Restricted data (Your Telemetry setting)

There is some data in the UDP that you may not want other players seeing if you are in a multiplayer game. This is controlled by the “Your Telemetry” setting in the Telemetry options. The options are:

- Restricted (Default) – other players viewing the UDP data will not see values for your car
- Public – all other players can see all the data for your car

Note: You can always see the data for the car you are driving regardless of the setting.

The following data items are set to zero if the player driving the car in question has their “Your Telemetry” set to “Restricted”:

#### Car status packet

- m_fuelInTank
- m_fuelCapacity
- m_fuelMix
- m_fuelRemainingLaps
- m_frontBrakeBias
- m_ersDeployMode
- m_ersStoreEnergy
- m_ersDeployedThisLap
- m_ersHarvestedThisLapMGUK
- m_ersHarvestedThisLapMGUH

#### Car damage packet

- m_frontLeftWingDamage
- m_frontRightWingDamage
- m_rearWingDamage
- m_floorDamage
- m_diffuserDamage
- m_sidepodDamage
- m_engineDamage
- m_gearBoxDamage
- m_tyresWear (All four wheels)
- m_tyresDamage (All four wheels)
- m_brakesDamage (All four wheels)
- m_drsFault
- m_engineMGUHWear
- m_engineESWear
- m_engineCEWear
- m_engineICEWear
- m_engineMGUKWear
- m_engineTCWear

## FAQS

### How do I enable the UDP Telemetry Output?

In F1 2021, UDP telemetry output is controlled via the in-game menus. To enable this, enter the options menu from the main menu (triangle / Y), then enter the settings menu - the UDP option will be at the bottom of the list. From there you will be able to enable / disable the UDP output, configure the IP address and port for the receiving application, toggle broadcast mode and set the send rate. Broadcast mode transmits the data across the network subnet to allow multiple devices on the same subnet to be able to receive this information. When using broadcast mode it is not necessary to set a target IP address, just a target port for applications to listen on.

Advanced PC Users: You can additionally edit the game’s configuration XML file to configure UDP output. The file is located here (after an initial boot of the game):

```
...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml

```

You should see the tag:

```xml
<motion>
  ...
  <udp enabled="false" broadcast=”false” ip="127.0.0.1" port="20777" sendRate=”20” format=”2021” yourTelemetry=”restricted” />
	  ...
</motion>
```

Here you can set the values manually. Note that any changes made within the game when it is running will overwrite any changes made manually. Note the enabled flag is now a state.

### What has changed since last year?

F1 2021 sees the following changes to the UDP specification:

- Car Damage packet including new engine wear parameters, brakes damage and more detailed body damage included. Some data sizes changed.

- Damage and wear parameters moved from car status packet to car damage for consistency and to more efficiently use space
- Block rev lights have been added for showing more accurate rev light LED arrays

- Session packet has been updated with more detailed weather forecast together with accuracy setting

- Nationality IDs have been updated

- Session types have been updated

- Adding new track Ids

- Added car number in the lobby info packet

- Network identifier added to participants – previously the network Id was offset by 100, but this could be confused with valid Driver Ids as they go over 100 now

- Updated Result Status values

- Added AI difficulty to the session packet

- Added My Team flag to participants and now set invalid driver, team, nationality & network ids to 255

- Added number of pit stops to the lap data

- New “Start lights” and “Lights out” events

- Added identifiers into the session packet so data sets can be linked

- Pit stop window data for the player has been added to the session packet

- Pit stop timings for all vehicles are now available in the lap data

- New session history packet gives details of lap times and tyre usage across the session

- Removed best lap/sector times/lap numbers from Lap Data packet as all this information is now available in the Session History packet

- Assists for local player are now in the session packet

- Added num penalties unserved into lap data and events for when drive through and stop-go penalties are served

- Added num warnings a driver has been issued in the lap data

- Added network paused flag to the car status (for every car)

- Flashback event added to help figure out discontinuities in the data

- Added dynamic racing line assists

- Lap times are now all in milliseconds (lap data and final classification packets affected)

- Lap valid flags added to the session history

- Added new event for button status so it can be detected throughout the game, not just driving

- Removed the button status from the car telemetry packet as the event packet is now available

### What is the order of the wheel arrays?

All wheel arrays are in the following order:

- 0 – Rear Left (RL)
- 1 – Rear Right (RR)
- 2 – Front Left (FL)
- 3 – Front Right (FR)

### Do the vehicle indices change?

During a session, each car is assigned a vehicle index. This will not change throughout the session and all the arrays that are sent use this vehicle index to dereference the correct piece of data.

### What encoding format is used?

All values are encoded using Little Endian format.

### Are the data structures packed?

Yes, all data is packed, there is no padding used.

### Will there always be 20 cars in the data structures?

No, for F1 2020, there is a new feature called “My Team” which allows an extra team to be present on the grid. This means that all previous places where 20 cars were used, 22 is now the maximum. If “My Team” is not active however, most games modes will act as before and have a maximum of 20. Note that if your UDP format is 2019, 2018 or legacy and you are in “My Team” career mode, no UDP output will be produced because of this limitation.

There is still the data item called `m_numActiveCars` in the participants packet which tells you how many cars are active in the race. However, you should check the individual result status of each car in the lap data to see if that car is actively providing data. If it is not `“Invalid”` or `“Inactive”` then the corresponding vehicle index has valid data.

### How often are updated packets sent?

For the packets which get updated at “Rate as specified in the menus” you can be guaranteed that on the frame that these get sent they will all get sent together and will never be separated across frames. This of course relies on the reliability of your network as to whether they are received correctly as everything is sent via UDP. Other packets that get sent at specific rates can arrive on any frame.
If you are connected to the game when it starts transmitting the first frame will contain the following information to help initialise data structures on the receiving application:

#### Packets sent on Frame 1: (All packets sent on this frame have “Session timestamp” 0.000)

- Session
- Participants
- Car Setups
- Lap Data
- Motion Data
- Car Telemetry
- Car Status
- Car Damage

As an example, assuming that you are running at 60Hz with 60Hz update rate selected in the menus then you would expect to see the following packets and timestamps:

#### Packets sent on Frame 2: (All packets sent on this frame have “Session timestamp” 0.016)

- Lap Data
- Motion Data
- Car Telemetry
- Car Status

…

#### Packets sent on Frame 31: (All packets sent on this frame have “Session timestamp” 0.5)

- Session (since 2 updates per second)
- Car Setups (since 2 updates per second)
- Lap Data
- Motion Data
- Car Telemetry
- Car Status
- Car Damage (since 2 updates per second)

### Will my old app still work with F1 2021?

F1 2021 uses a new format for the UDP data. However, earlier formats of the data are still supported so that most older apps implemented using the previous data formats should work with little or no change from the developer. To use the old formats, please enter the UDP options menu and set “UDP Format” to either “F1 2020”, “F1 2019”, “F1 2018” or “Legacy” (for F1 2017 and earlier).
Specifications for the olders formats can be seen here:

- Legacy (2017 and earlier) - http://forums.codemasters.com/discussion/53139/f1-2017-d-box-and-udp-output-specification/p1.
- F1 2018 - https://forums.codemasters.com/topic/30601-f1-2018-udp-specification/
- F1 2019 - https://forums.codemasters.com/topic/44592-f1-2019-udp-specification/
- F1 2020 - https://forums.codemasters.com/topic/54423-f1%C2%AE-2020-udp-specification/

### How do I enable D-BOX output?

D-BOX output is currently supported on the PC platform. In F1 2021, the D-BOX activation can be controlled via the menus. Navigate to `Game Options->Settings->UDP Telemetry Settings->D-BOX` to activate this on your system.

Advanced PC Users: It is possible to control D-BOX by editing the games’ configuration XML file. The file is located here (after an initial boot of the game):

`...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml`

You should see the tag:

```xml

```

Set the `“enabled”` value to `“true”` to allow the game to output to your D-BOX motion platform. Note that any changes made within the game when it is running will overwrite any changes made manually.

### How can I disable in-game support for LED device?

The F1 game has native support for some of the basic features supported by some external LED devices, such as the Leo Bodnar SLI Pro and the Fanatec steering wheels. To avoid conflicts between Codemasters’ implementation and any third-party device managers on the PC platform it may be necessary to disable the native support. This is done using the following led_display flags in the hardware_settings_config.xml. The file is located here (after an initial boot of the game):

`...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml`

The flags to enabled/disable LED output are:

```xml

<led_display fanatecNativeSupport="true" sliProNativeSupport="true" />

```

The sliProNativeSupport flag controls the output to SLI Pro devices. The fanatecNativeSupport flag controls the output to Fanatec (and some related) steering wheel LEDs. Set the values for any of these to “false” to disable them and avoid conflicts with your own device manager.

Please note there is an additional flag to manually control the LED brightness on the SLI Pro:

```xml
<led_display sliProForceBrightness="127" />
```

This option (using value in the range 0-255) will be ignored when setting the sliProNativeSupport flag to “false”.

Also note it is now possible to edit these values on the fly via the Game Options->Settings->UDP Telemetry Settings menu.

### Can I configure the UDP output using an XML File?

PC users can edit the game’s configuration XML file to configure UDP output. The file is located here (after an initial boot of the game):

`...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml`

You should see the tag:

```xml
   <motion>
     ...
     <udp enabled="false" broadcast=”false” ip="127.0.0.1" port="20777" sendRate=”20” format=”2021” yourTelemetry="restricted" />
     ...
   </motion>
```

Here you can set the values manually. Note that any changes made within the game when it is running will overwrite any changes made manually.
