How can I change the port number? (ZeroMQ API - python)

[wenyu]

Hello!
I use the ZeroMQ remote API for Python. How can I change the port number?
python :

Code: Select all

client = RemoteAPIClient(host='localhost', port=23005)
sim = client.getObject('sim')

But I don't know how to change the corresponding port number in vrep V4.5.
Thanks.

You can start CoppeliaSim passing the command line parameter -GzmqRemoteApi.rpcPort=23005.

Or with CoppeliaSim already started, execute sim.setNamedInt32Param('zmqRemoteApi.rpcPort',23005) (e.g. in the lua commander at bottom of screen) and then restart the ZMQ Remote API server addon.

Thanks for your reply, but it doesn't work.
execute sim.setNamedInt32Param('zmqRemoteApi.rpcPort',23005), and restart python program. The robot doesn't respond.

Hello,

make sure to identify the source of the problem. When you say the robot doesn't respond, this doesn not necessarily mean that the remote API cannot communicate with CoppeliaSim. Is there an error message on the client or CoppeliaSim side, and if yes, what does it say?

Cheers

... and then restart the ZMQ Remote API server addon.

That is done via the menu Modules -> Connectivity -> ZMQ Remote API Server

Thanks for your reply. It helped me a lot.

For me, the -Gxx parameter does not work.

I used

Code: Select all

coppeliaSim.exe -c"sim.setNamedStringParam('zmqRemoteApi.rpcPort',23005)"

and it works

For me, the -Gxx parameter does not work.

Make sure to use the latest version of CoppeliaSim.

One of the previous 4.6.x releases had a bug with -G options.
