I have just started working on SOME/IP protocol. “Our objective is having two PCs connected With the ethernet cable and achieve inter-PC communication”.
The current setup:

  1. 2 PCs with Ubuntu 18.04
  2. Common API, VsomeIP, Boost library, SOME/IP has been installed.
  3. Configured static IP(locally) for both the PCs.

Followed below links as a part of our study:

[1] https://genivi-oss.atlassian.net/wiki/spaces/COMMONAPICPP/pages/547232 /CommonAPI+C+SOME+IP+in+10+minutes
[2] https://github.com/GENIVI/vsomeip/wiki/vsomeip-in-10-minutes

We have successfully achieved the Client-Server communication on a single machine for both VSOMEIP alone[2] and also common API SOME/IP[1]. But during inter-PC communication we are facing a serious issue.

i.e. On running Client and Server on two different machines connected through ethernet cable, The client is capable of discovering the presence and absence of the server. But the client is not capable of initiating the function call (rpc).

We thought the issue might be in the json file and tried a multiple experiments on json for a week. But even then we were not able to achieve communication. (We are using the JSON as given in the link [2] )

On running Client and Server on two different machines connected through ethernet cable, The client is capable of discovering the presence and absence of the server. But the client is not capable of initiating the function call (rpc).

Any suggestion will help me a lot.

thanks,
