Recently I have received a CBT and now I got arount with looking into it. First of all, i searched the forums, but couldn't really find what I was looking for.

I'm trying to send a basic OBD-II message and want to see the response, such as for example listing the available PIDs or retrieving the current engine speed. I was trying both CoolTerm as the CBT application. I can connect to my COM port, issue a debug command ("01 10 01") and also see CAN packets in both CoolTerm and CBT. Now I'm trying to send the correct OBD-II commands, but I get no response. Not actually sure how it should look like and if I for example first have to enter a specific mode for these specific OBD-II commands. For example:
"02 01 0D" gives no output.

Any help would be appreciated. Thanks!

Looks like your connection to CANBus Triple was lost, please wait while we try to reconnect.
