+## Issue 18: On SuperCharger we ignore the session ID
+- In the SessionSetupResponse, the SuperCharger V3 correctly provides a sessionID, e.g. "06ef0071".
+- But we ignore this, and send in all next messages (starting with ServiceDiscoveryReq) the sessionID "deadbeefdeadbeef".
+- The SuperCharger correctly complains with "ResponseCode": "FAILED_UnknownSession".
+- observed with Software version v0.5-12-g23b1384, on 2023-03-02.
+- root cause: In main_commandlineinterface.c we check, whether the session ID has 16 characters, to represent 8 hex bytes.
+But the SuperCharger provides 8 characters, to present 4 bytes. Thats why the function useSessionIdFromCommandLine()
+operates with the default session ID "deadbeefdeadbeef".
+- solution: in function useSessionIdFromCommandLine(), also accept shorter session IDs. And in function init_dinMessageHeaderWithSessionID(),
+use a dynamic length instead of the fixed length LEN_OF_SESSION_ID (=8).
