Hi，I have some questions about B0-basedRemoteApiDemo.ttt，
When I run it, it always warns that：

B0 resolver was not detected. Launching it from here...
B0 resolver could not be launched.

What should I do to complete the remote connection？

In the working folder I have prepared all the required libraries，When I run, it always stops on initialization

Hello,

can you try following?

In file CoppeliaSimInstallFolder/lua/b0RemoteApiServer.lua, replace
with
Let me know if that makes a difference.

Also, when you manually try to run B0Resolver, what is the output exactly?

Cheers

Thank you very much for your answer！

I'm trying to communicate with vrep using matlab.

I modified the code and ranB0-basedRemoteApiDemo.ttt，then start script in the menu bar [Add-ons --> b0RemoteApiServer]，The output is：
“
[15:08:06] B0 Remote API: creating BlueZero node 'b0RemoteApi_V-REP' and associated publisher, subscriber and service server (on channel 'b0RemoteApi')
B0 Remote API: B0 resolver was not detected. Launching it from here...
[15:08:25] B0 Remote API: B0 resolver could not be launched.
[15:09:47] B0 Remote API (add-on): creating BlueZero node 'b0RemoteApi_CoppeliaSim-addOn' and associated publisher, subscriber and service server (on channel 'b0RemoteApiAddOn')
B0 Remote API: B0 resolver was not detected. Launching it from here...
[15:10:06] B0 Remote API (add-on): B0 resolver could not be launched.
”

When I run B0Resolver manually，The B0Resolver window only appears for a while and then disappears，Then nothing happened

can you tell me what platform you are running on?
Also, can you try to start b0_resolver from the DOS console or the Ubuntu terminal and tell me the output?

Thanks

hello，coppelia！

Thanks for your reply!

My platform is WINDOWS10, I cannot start b0_resolver from DOS。If I run it with administrator privileges alone, the window of

b0_resolver is only displayed for a while without any output。

Also when I open B0-basedRemoteApiDemo.ttt, this will appear in the middle of the scene：

‘’CUSTOMIZATION SCRIPT b0RemoteApiServer: abort execution‘’

Thank you. I meant to say: start b0_resolver in the DOS console (i.e. by typing b0_resolver.exe<return>, not by double-clicking it). What is the exact output of the DOS console? Also, make sure to run b0_resolver from the CoppeliaSim installation folder, since b0_resolver depends on other dlls.

Cheers

hi，coppelia

I started b0_resolver with DOS, and then there was no response, not even the b0_resolver interface, and there was output

like this:

"C:\Program Files\CoppeliaRobotics\CoppeliaSimEdu>b0_resolver.exe

C:\Program Files\CoppeliaRobotics\CoppeliaSimEdu>"

What should i do to solve this？

What does it say if you type:
?

Thank you very much for your reply！

If I type the above code, the output of DOS is that：

“C:\Program Files\CoppeliaRobotics\CoppeliaSimEdu>b0_resolver.exe -Ldebug
2020-01-21 16:23:49 [resolver] debug: Initialization...
2020-01-21 16:23:49 [resolver] debug: ServiceClient(resolv): Skipping resolution because remote address (tcp://御坂美琴:
22000) was given

C:\Program Files\CoppeliaRobotics\CoppeliaSimEdu>”

Thanks again for your help, but I am going to use the old version of the remote API. Thanks！

Hi,

could it be that your machine it is not reachable by its host name (御坂美琴) via the IP protocol?

Try executing the following
before running b0_resolver (replace 127.0.0.1 with your local IP address if you are using multiple machines).
