6.3.3 PASS Mode for the Serial Interface

When the CLI Session on the serial interface attempts a transition to PASS

Mode, the CLI Server establishes an outbound connection from the Airborne™

WLN Module to a user-specified TCP server and/or UDP server on the wireless

interface. Once a connection is established, data bridging becomes possible

between the CLI Session on the serial interface and the TCP Server and/or UDP

server. If the connection to the primary TCP server failed, the CLI Server will

attempt to connect to a secondary TCP server, if configured. If the transition to

PASS Mode was triggered by the automatic startup configuration, the CLI Server

will use the wl-retry-time configuration parameter to continuously retry

connection to the servers.

The IP addresses of the primary TCP and UDP servers are configured using wl-

tcp-ip and wl-udp-ip CLI commands. The secondary TCP server is

configured using the wl-tcp-ip2 command. The TCP server port is

configured using wl-tcp-port and wl-udp-port CLI commands. The retry

timer is configured using the wl-retry-time CLI command. See section “CLI

Commands” for more details on these commands.

6.3.4 PASS Mode for the Wireless Interface

When the CLI Session on the wireless interface attempts to transition to PASS

Mode, the CLI Server establishes a data bridge to the CLI Session on the serial

interface if the following conditions are both true:

 The CLI Session on the serial interface is in LISTEN Mode.

 No other CLI Session on the wireless interface is in PASS Mode.

6.3.5 LISTEN Mode (Serial/UART/SPI Interface Only)

LISTEN Mode is a passive data bridging mode of the CLI Session. The LISTEN

Mode is only applicable on the serial interface. When the CLI Session on the

serial interface enters LISTEN Mode, the Airborne™ WLN Module passively

waits for a data bridge to be established over the wireless interface. The data

bridge may be initiated using a CLI Session via the PASS Mode or using the

tunneling feature. The CLI Session may transition to CLI Mode using CLI Server

escape processing. See section “CLI Server Escape Processing” for details.

When the serial interface CLI Session is in LISTEN Mode, the following are

possible:

 TCP connections on the wireless interface can use the CLI commands pass,

putget or putexpect to establish a data bridge.

 TCP connection can establish a data bridge if tunneling is enabled.

6.3.6 CLI Session Startup Modes

The startup behavior of the CLI Session on each interface is determined as

follows:

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 119 120
