How to echo can frames?

[DPons97]

Hi GVRET_comm-unity!
First of all I'd like to thank @collin80 for this tool. I just started a project where I need to reverse engineer the CAN bus messages of a motorcycle and this will be for sure extremely helpful 🙌.

Now with the question. As the title says, I want to debug my implementation of the GVRET protocol on STM32 to see if I am doing everything correctly. I managed to connect the device and have the keep-alive messages coming back and forth. I'm also able to send can frames from SavvyCAN and see them being processed by the mcu. However, I can't find a way to generate a ECHO_CAN_FRAME message directly from SavvyCAN.

The easiest solution would be to temporarily swap the ECHO_CAN_FRAME and BUILD_CAN_FRAME ids on the stm firmware, but I am curious to know if there is a way to obtain the same behavior directly from SavvyCAN UI. I see there is a fuzztest feature (very helpful btw), but there is no way to choose between SEND and ECHO.
