  .. code-block:: console

     uart:~$ rfcomm  register
     RFCOMM channel 5 registered
     Security changed: XX:XX:XX:XX:XX:XX level 2
     Incoming RFCOMM conn 0x20004dc8
     Dlc 0x20000d20 connected

.. group-tab:: Initializing device

  .. code-block:: console

     uart:~$ rfcomm connect 5

     uart:~$ rfcomm send 1
     Incoming data dlc 0x20000d20 len 30

Disconnect

Create disconnect request from non-initializing device:

.. tabs::

.. group-tab:: Non-initializing device

  .. code-block:: console

     uart:~$ rfcomm disconnect
     Dlc 0x20000d20 disconnected
     uart:~$

.. group-tab:: Initializing device

  .. code-block:: console

     Dlc 0x20000d20 disconnected
     uart:~$

Create disconnect request from initializing device:

.. tabs::

.. group-tab:: Non-initializing device

  .. code-block:: console

     Dlc 0x20000d20 disconnected
     uart:~$

.. group-tab:: Initializing device

  .. code-block:: console

     uart:~$ rfcomm disconnect
     Dlc 0x20000d20 disconnected
     uart:~$
