v-rep link to matlab with remote api

Post by rasool » 19 May 2017, 15:56

i want to link v-rep to matlab with remote api, and i have read help , and did this step;
((
Make sure you have following files in your directory, in order to run the various examples:
1. remApi.m
2. remoteApiProto.m
3. the appropriate remote API library: "remoteApi.dll" (Windows), "remoteApi.dylib" (Mac) or "remoteApi.so" (Linux)
4. simpleTest.m (or any other example program)
))
but when I run "simpleTest.m", I see this error.
"Failed connecting to remote API server"
can you please help me?

Hello,

did you start a remote API server service on port 19999 on the V-REP side? You can also try to connect to port 19997, where you have a remote API server service running by default.

Cheers

hello,

in v_rep side you must add new non_treaded child script "add-associate child script-non_treaded, and write in the script this command "simExtRemoteApiStart(19999)".

and when you start the simulation. you must run first v_rep, then your programme in matlab.

hope i can help you here.

I did all these guidances, but when I run "simpleTest.m" that exists on this path: (V-REP_PRO_EDU\programming\remoteApiBindings\matlab\matlab)
I face with this message:
"Connected to remote API server
Number of objects in the scene: 16
Mouse position x: 283"
and when I run "simpleSynchronousTest.m" on the same path as previous. I face with this message:
"Failed connecting to remote API server
Program ended"
what does this mean?
can you please help me?

hi my friend you must be more vigilant, when you open simpletest code, you find v_rep adresse "19999" as below:
function simpleTest()

clientID=vrep.simxStart('127.0.0.1',19999,true,true,5000,5);

but it's not same in in simpleSynchronousTest code, its "19997".


function simpleSynchronousTest()

clientID=vrep.simxStart('127.0.0.1',19997,true,true,5000,5);

you must change it to connecte to "19999" your scene on v_rep.

good luck.
