How to use UDP/TCP to transfer json files in real time? OR:怎么使用UDP​/TCP实时传输js​on文件？

We need to transfer the data containing json between Speedgoat and a device, receiving and sending it in simulink:

The data format is: fixed 18-byte header + variable length JSON + 1-byte checksum

We want to implement real-time transmission of JSON file/variable length JSON data based on Speedgoat. The current difficulty is how to unpack json using unpack module? Or can you choose another appropriate way?

OR:

我们需要将Speedgoat与某设备传输含json的数据，在simulink里接收和发送：

数据格式为：固定 18 字节头 + 变长 JSON + 1 字节校验和

我们想实现基于Speedgoat的JSON文件/变长 JSON数据实时传输，目前困难是怎么使用unpack模块解包json？还是可以选择其他合适的方式？

Hello Yue,

MATLAB doesn’t have a built-in unpack module specifically for JSON, but you can use MATLAB’s 'jsondecode' function to parse JSON data.

Please refer to the documentation of 'jsondecode' function given below:

https://in.mathworks.com/help/matlab/ref/jsondecode.html

I hope this helps!

Thanks

jsondecode does not appear to be supported by MATLAB Coder.
