+**Summary:**
+V2X Hub release 7.2.2 includes added Hotfix for CARMACloud Plugin to prevent repeated TCM broadcast.V2xhub can control the number of times each TCM being repeatedly broadcast upon receiving TCMs from carma-cloud. After it repeatedly broadcasts the TCMs, it waits for a configured time duration before it sends a time out message to carma-cloud notifying that no response from CMV for TCMs. The no response message will be displayed as a warning on the v2xhub admin user interface. If V2xHub receives an acknowledgement from CMV, it will stop broadcasting TCMs and display the acknowledgement on the v2xhub admin user interface:
