I have to read the data provided by ScaLa(B2)-LIDAR,through a Ethernet port. In general Ibeo software is used to read the data from LIDAR using ehternet port,if we save the data provided by the Ibeo software it is in .ibc format.Now i need to use MATLAB to read the data provided by the LIDAR, Please help me in doing it? what toolboxes I need to do read Ethernet port? How to read .idc files by using MATLAB?

Hi Kintali,
would be nice to know if you could solve the issue (and if so how?)? I know that Ibeo offers an SDK to read in LIDAR data, so that could be a starting point to get the data into Matlab...

You need the Instrument Control toolbox, or the File Exchange contribution https://www.mathworks.com/matlabcentral/fileexchange/345-tcp-udp-ip-toolbox-2-0-6
In new enough MATLAB versions (R2014b and later), there is also tcpclient()

... or you can defer to java or on Windows, .Net, both of which can be called straight from matlab.
It's fairly trivial to receive tcp or udp packets with either. Crucially missing from the question, however, is what protocol is used for the communication. Ethernet port is not a communication method.

i dont know too!
tcp ip in matlab is so difficult... rs232 and com is very easyer!
:
problem 1:
clear
clc
t= tcpclient('localhost', 56666);
Cannot create a communication link with the remote server. Please check the input arguments(ADDRESS and PORT) and make sure the
server is running.
Additional Information: No connection could be made because the target machine actively refused it.
problem2:
why ECHO in this case doesnt work?
we was able to echo character between pc and AVR! so right nowe what is the correct command similar to ECHO for testing tcpip function?(in matlab2011)

t= tcpclient('localhost', 56666);
However it looks like the device you need to connect to is on 192.168.0.1 not on 'localhost'
As your current IP address is 172.16.0.15 then as I am not able to see the full ethernet information (such as the VMWare ethernet information) I cannot tell that your system also has IP existence on 192.168.0.x . Possibly you need to reconfigure the device to have a 172.16.0.x address (other than 172.16.0.15, and probably not 172.16.0.1 or 172.16.0.255 either.)
