Simulink: How to interpret received UDP data/packet?

I use simulink udp receive block to receive UDP packet from a PC. The packet sent by the PC is according to a C header file. It contains a structure with a lot of signals of different data type. E.g., signal 1 uint8, signal 2 double, etc. The data is also begin with a header stating who is the sender and what size is the data.

After receiving the raw data, how can I use simulink to interpret the data?

Hi Guoguang,

You can consider using a Byte Unpack block to interprest the received UDP packets. There is a shipped Simulink example model that demonstrates this.

To open the model, execute the following command in MATLAB Command Window:

>> udpsendreceiveA
