Posted on July 31, 2016 at 22:42Hello everyone,
I am using stm32f746 discovery board and I am sending 10 bytes of data in UDP protocol to PC.
I can trace the data coming through LAN using WireShark application. for example
No. Time Source Destination Protocol Len Info
14 1.300032 192.168.1.5 192.168.1.42 UDP 60 49153 ? 64701 Len=10
that 192.168.1.5 is STM32 board and 192.168.1.42 is PC
the data is sent to Port 64701 by STM32 Board
I used this code in matlab :
u = udp ('192.168.1.5', 'LocalPort', 64701);
fopen(u);
x = fread(u, 10);
disp(x)
fclose(u)
But I can't get data and timeout in reading occurs. unfortunately the internet space is getting so complicated and is full of too detailed notes, related to the topic though, so I couldn't find what the problem is. within couple of hours.
can anyone help me and get me out of this trap?
thanks in advance
#stm32f746
