I am writing a CAPL script to mimic a CAN message on network. While I am getting intended message, direction is both Tx & TxRq. How I can filter out and send only Tx message.
I tried CANID.dir=1 (tx) however not getting intended result.
I tried, setting direction as CANID.dir=1 (tx).
According to your screenshot, I assume took from the Trace window, you are looking at duplicate entries that spark confusion.
The entries marked as Tx are telling you that there is, indeed, a CAN frame with direction "outgoing" from your measurement system (your Vector Node).
The entries marked as TxRq are send requests. You may change settings for send requests in the Vector Hardware Configuration tool (ref).
TxRq is not a "direction" per se, just a way to indicate a different type of log in the Trace window. Remember that the only directions available are Tx and Rx (all frames either go out of your node or come into your node).
More about send requests. The following is an extract, I don't remember from which Vector knowledge base entry
By default, this box [the one in the Vector Hardware Configuration] is unchecked because most users do not require this feature. This feature displays the
TxRqmessages with a time stamp in the Trace window of CANoe. These are requests to send messages by CANoe that have not yet been transmitted onto the CAN bus. If they have been transmitted on the CAN bus, they would beTxmessages.
