Hi,

This is an Integer data type:

You can see a pin's data type at the bottom left cornet in the Flow Editor when you hover your mouse over it:

You can directly connect scalar or vectors to integer pins and Aximmetry will automatically convert them. You can connect other data types too, but usually, you need some modules in between, for example:

Since I am not sure what kind of data you importing from the JSON and in what type of data format you need it in Unreal, I can not tell what modules you will need to use.
Note, you can peek at any pin in Aximmetry to get a better idea of what is going on inside your module and data: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/starting-with-aximmetry/aximmetry-composer/basics-of-the-flow-editor/#peeking

Also, in most cases, you don't need a logic like this:

Aximmetry automatically detects if the file changes and updates the JSON File module's output.

Warmest regards,

Hi Cleveland,

You do not need to use LUA for your task. Instead, you can utilize the following modules in the Flow Editor:

Note that I connected the Timer's Elapsed pin, rather than the Time pin like in the original post.

By following the above screenshot you should be able to achieve a consistent 1-second update interval for your heart rate data in Aximmetry. Additionally, the Hold Collection module, along with the connected logic, will guarantee that only the usable heart rate data is displayed.

Should you have any more questions or require additional guidance, please feel free to reach out.

Warmest regards,

Hi Eifert thank you very much for your help.

I decide use script and it works fine. Below the code I developer for my goal. The nodes tha you show it good but yet dosen't up date in real time. My code works fine. Thank you very much for your help. 

--$ outClientID Text
--$ outBatimento Text
--$ outDebug Text

-- Importa a bilbioteca para leitura do json
local cjson = require ("dkjson")

-- Para colocar um diretório usar estas barras /
local dados = "M:/Batimento_Axi/ dados.json"

--Tenta abrir o arquivo em modo de leitura
local arquivo, erro = io.open(dados,"r")

-- Verifica se houve um erro na abertura do arquivo
if not arquivo then
    outDebug = "Erro ao abrir o arquivo"
    outDebug = erro
else
    -- Lê o conteúdo do arquivo
    local conteudo = arquivo:read("*all")
    
    -- Fecha o arquivo após a leitura
    arquivo:close()

    -- Converte a string JSON para uma tabela Lua
    local tabela_lua, pos, err = cjson.decode(conteudo, 1, null, nil)
    if err then
        --outDebug = err
        
    else 
        outClientID = tabela_lua.clientId
        outBatimento = tostring(tabela_lua.hr)
        
    end
end

Hello Cleveland,

Thank you for sharing the LUA script.

I forgot to mention that if you are retrieving this JSON data from the web, you can probably directly utilize the HTTP Request module in the Broadcast version of Aximmetry. This way you can skip saving the JSON into a file and reading the file in Aximmetry. Additionally, starting from version 2023.3.0 BETA, you have access to the WebSocket Client, TCP Client, TCP Server, UDP Sender, UDP Receiver, and Serial Client modules. These modules enable you to receive data from the internet, local network, and from various devices.

The JSON in my screenshot is updated every second. However, they do not update during the 1-second intervals. If you wish to achieve updates more frequently than every second, you could incorporate a Not module after the Timer module. This would keep the JSON file module Open between the 1-second intervals:

Alternatively, consider leaving the JSON File module Open and removing the Timer module altogether. I believe that it should update in less than a second like that, but not in regular intervals.

Warmest regards,
