I'm wondering if there is a way to set ELM327 to listen on the bus. Apparently the ELM only listens when a command is been sent to wait for the response, but what I want is to display all the received frames instead of just the response

ATMA is the command you want to use. Be warned though, the ELM327 has a very tiny buffer so you will be presented with a Buffer full error after just a few frames.
If you seriously want to listen to the bus, you either need to use a STN11xx or STN22xx derived OBD2 adapter, or – if it's a CAN bus – a CAN2USB adapter.
