1. CLI Presentation
This application aims to evaluate and to test the ST67W611M Wi-Fi® solution via command line interface (CLI).
It exercises the network co-processor (ST67W611M) capabilities embedding the LwIP Wi-Fi® stack and Bluetooth LE® stack. It relies on the FreeRTOS RealTime operating system to manage the ST67W611M expansion board.
The application enables basic Wi-Fi® operations, such as scanning available local access points (APs) and connecting to an AP. It also supports testing LwIP functionalities such as DHCP, pinging URLs or specific IP addresses, MQTT, and IPerf.
The application enables also basic Bluetooth LE® functionalities like scanning, connecting and advertising.

Commands description:
In this project, the following convention is used for getting and setting values. When a command is issued without a parameter, it acts as a "get" operation. Adding a parameter makes it a "set" operation. This applies to all commands capable of "get" functionality. For example:
w61/>wifi_sta_ip
Return the station, gateway, and netmask IPs.
w61/>wifi_sta_ip 192.168.1.2
Sets the Station IP value to 192.168.1.2.
Convention:
The parameters which are between < > are mandatory, while those in [ ] are optional and not required in all cases.
3.4.2. System commands
- help [ command ]
This command is used to display the global help message describing all the available commands and their summary if no argument is given.

|---|---|
| Mandatory | |
|
ssid |
The SSID of the local access point to connect to. |
| Optional | |
|
Password |
This option is needed only if the local access point uses WPA, WPA2 or WPA3 security. |
|
-b <BSSID> |
This option specifies the BSSID of the access point to connect if there are multiple access points with the same name. |
| -i <interval> | This option specifies the reconnection interval between connection/reconnection attempts if the first one does not pass. Default value 0: the station does not reconnect to the AP when disconnected, range: [0;7200]. The value is expressed in seconds. |
| -n <nb_attempts> | This option specifies the number of reconnection attempts in case the initial connection or reconnection fails. Default value: 0 (always try to reconnect), range: [0;1000] |
This command executes a scan to retrieve the information needed for the connection, including the security of the access point.
Example:

w61/>wifi_auto_connect
Get auto-connect state succeed.
Auto-connect state : 1
- wifi_sta_disconnect [ -r ]
This command disconnects the station from a network.
The -r option removes the registered SSID and password of the previously connected access point.
Example:
w61/>wifi_sta_disconnect Reason: WLAN_FW_DISCONNECT_BY_USER_WITH_DEAUTH Station disconnected from Access Point
The "reason" of the disconnection is returned after each disconnection. Below is a list of the different reasons:
- 1: Failure to allocate memory for transmitting an authentication frame.
- 2: Authentication process failed.
- 3: The authentication algorithm was not accepted or failed.
- 4: Failure to allocate memory for transmitting an association frame.
- 5: Association process with the access point failed.
- 6: De-authentication by the access point occurred when not connected.
- 7: De-authentication by the access point occurred while connected.
- 8: A timeout occurred during the 4-way handshake, likely due to PSK (pre-shared key) issues.
- 9: Failed to transmit a de-authentication frame during the 4-way handshake.
- 10: Failed to allocate memory for a de-authentication frame during the 4-way handshake.
- 11: Timeout waiting for authentication or association response.
- 12: No BSSID or channel found during the scan process.
- 13: Failed to create a channel context when attempting to join a network.
- 14: Failure to join a network.
- 15: Failed to add a station (STA) to the network.
- 16: Beacon loss occurred, potentially leading to disconnection.
- 17: The network security settings do not match.
- 18: An error occurred due to an incorrect WEP key length.
- 19: User-initiated disconnection with de-authentication.
- 20: User-initiated disconnection without sending a de-authentication frame.
- 21: Disconnection occurred because the firmware failed to send a power-save null frame.
- 22: Traffic loss was detected.
- 23: Switching to a new channel failed.
- 24: Confirmation of authentication or association response failed.
- 25: Reassociation process is starting.
- wifi_sta_mac
This command prints the MAC address of the station interface.
Example:
w61/>wifi_sta_mac STA MAC : 8c:fd:f0:fd:8f:41
- wifi_sta_dns [ 0:default IPs; 1: manual IPs ] [ DNS1 addr ] [ DNS2 addr ] [ DNS3 addr ]
This command sets or reads the DNS configuration of the station. The first parameter specifies if the user wants to use the default DNS IP addresses or manually enter them.
