RBT communication on L2CAP level

For RBT to establish link local and remote RFCOMM port is needed. I would like to communicate with a device that does not have RFCOMM implemented, but only L2CAP. Is this possible?

I tried using SDAP_CONNECT opcode, but in CFM packet I get information that command is disallowed.

I tried usind SDAP_SERVICE_BROWSE, still nothing.

ESTABLISH_LINK I cannot use, since there is no remote RFCOMM port.

I tried to send raw data (HCI Inquiry) using SPP_SEND_DATA, but CFM packet tells me that there is no connection (I want to send data usin connectionless link, and I get error message saying "NO_CONNECTION" ?!?!?!).

Is this even possible? To communicate on lower levels than RFCOMM, or to just send bytes in the air (raw data)?

Thank you.
