| Bluetooth: L2CAP Shell |
| ###################### |
| |
| The :code:`l2cap` command exposes parts of the L2CAP API. The following example shows how to |
| register a LE PSM, connect to it from another device and send 3 packets of 14 octets each. |
| |
| The example assumes that the two devices are already connected. |
| |
| On device A, register the LE PSM: |
| |
| .. code-block:: console |
| |
| uart:~$ l2cap register 29 |
| L2CAP psm 41 sec_level 1 registered |
| |
| On device B, connect to the registered LE PSM and send data: |
| |
| .. code-block:: console |
| |
| uart:~$ l2cap connect 29 |
| Chan sec: 1 |
| L2CAP connection pending |
| Channel 0x20000210 connected |
| Channel 0x20000210 status 1 |
| uart:~$ l2cap send 3 14 |

| On device A, you should have received the data: |
| |
| .. code-block:: console |
