Part 5 - Periodically Transmit a Message

Often a message must be transmitted regularly. Rather than sit around clicking the Tx button all day, Vehicle Spy enables users to specify when and how often a message will be transmitted.

1. Set Auto Tx and Rate:

Look at the Tx Panel again and notice the Auto Tx and Rate columns. Previously these were left alone, but now these will be set up. Changing the Auto Tx column will change how the message is sent out. For this example leave it set to Periodic. Next, double click in the space directly to the right in the Rate column (Figure 1:). A dropdown arrow appears, that when clicked, shows a list of common values. If a specific value is needed and not found in the dropdown, it can typed into the field directly. For this tutorial, select 0.1 seconds from the dropdown. Vehicle Spy has been told to transmit the Practice TX Message periodically every 0.1 seconds.

2. Check Message Traffic:

After this is set up, look back at Messages view. If you are in scrolling mode, a steady stream of Practice Tx message should be seen flying by (Figure 1:). In static mode, Practice Tx Message should be highlighted and its message counter should be increasing rapidly.
