Single-chip microcomputer by udp sends the 32 bytes per 1 s to PC, is now receiving data, could you tell me how to use Delphi implementation will receive the data in an array, thus I can for each byte, like the inside of the STM32 definition u8 data [32], and then the data [0] can I assigned to variables,,,

Below is the demo, udp chat microcontroller every time sending a few directly into a question mark, how will receive adata in my definition of 32 bytes in length of an array? The great god give directions, thank you!
The function IdBytesToAnsiString (ParamBytes: TIdBytes) : AnsiString;
Var
I: Integer;
S: AnsiString.
The begin
S:=';
For I:=0 to Length (ParamBytes) - 1 do
The begin
S:=S + AnsiChar (ParamBytes [I]);
end;
Result:=S;
end;
