Parameters

  • <ssid>: SSID of the target AP

    • If there are special characters such as , , " and \\ in the SSID and password, they need to be escaped

    • AT supports connecting to APs with Chinese SSID, but some routers or hotspots have Chinese SSID that are not in UTF-8 encoding format. You can scan the SSID first, and then use the scanned SSID to connect.

  • <pwd> : A string parameter representing the password, ranging from 8 to 63 bytes in ASCII (or 64 bytes in HEX).

  • <bssid> : The MAC address of the target AP. This parameter cannot be omitted when multiple APs have the same SSID.

  • <channel> : The channel number

  • <rssi> : The signal strength.

  • <pci_en> : PCI certification

    • 0: w800 Station can connect to AP with any type of encryption method, including OPEN and WEP

    • 1: w800 Station can connect to AP with any type of encryption method except OPEN and WEP

  • <reconn_interval>: Wi-Fi reconnection interval, in seconds, default value: 1, maximum value: 7200

    • 0 : w800 Station will not reconnect to AP after disconnection

    • [1,7200]: w800 Station will reconnect to the AP at the specified interval after disconnection

  • <listen_interval>: Interval for listening to AP beacons, in units of AP beacon intervals, default value: 3, range: [1,100]

  • <scan_mode> : Scan mode

    • 0: Fast scan, The scan terminates after finding the target AP, w800 Station connects to the first detected AP

    • 1: Full channel scan, The scan terminates only after all channels have been scanned, w800 Station connects to the AP with the strongest signal

  • <jap_timeout> : The Maximum timeout value for the AT+CWJAP command, in seconds, default value: 15, range: [3,600]

  • <pmf>: PMF (Protected Management Frames), default value: 1

    • 0 : PMF disabled

    • bit 0: Indicates support for PMF, w800 device will prefer to connect in PMF mode if other devices also support PMF

    • bit 1: Indicates requirement for PMF, device will not associate with devices that do not support PMF

Note

  • If AT+SYSSTORE=1, the configuration changes will be saved to the NVS partition

  • This command requires station mode to be enabled.

  • When the w800 station has connected to an AP, it is recommended to use this command to query Wi-Fi information; when w800 Station is not connected to an AP, it is recommended to use AT+CWSTATE command to query Wi-Fi information

  • The <reconn_interval> parameter in this command is the same as the <interval_second>``parameter in the :ref:`AT+CWRECONNCFG <cmd-RECONNCFG>` command. If the ``<reconn_interval> parameter is not set when this command is executed, the default Wi-Fi reconnection interval of 1 will be used

  • If both <ssid> and <password> parameters are omitted, the last set values will be used

  • The timeout for executing the command and setting the command is the same, with a default value of 15 seconds, which can be set by the <jap_timeout> parameter

  • To obtain an IPv6 address,:ref:AT+CIPV6=1 <cmd-IPV6> must be set first

  • The response OK indicates that the IPv4 network is ready, but does not indicate that the IPv6 network is ready. Currently, WinnerMicro-AT prioritizes the IPv4 network, with the IPv6 network as a secondary option

  • WIFI GOT IPv6 LL indicates that a local link IPv6 address has been obtained, which is calculated locally using EUI-64 and does not require router involvement. Due to parallel timing,this print may appear before or after OK

  • WIFI GOT IPv6 GL indicates that a global IPv6 address has been obtained, which is a combination of the prefix issued by the AP and the suffix calculated internally, requiring router involvement. Due to parallel timing, this print may appear before or after OK ; it may also not be printed if the AP does not support IPv6

Examples

// If the SSID of the target AP is "WinnerMicro_WiFi" and the password is "12345678", the command is:
AT+CWJAP="WinnerMicro_WiFi","12345678"

// If multiple APs have the same SSID "WinnerMicro-WiFi", the target AP can be found through BSSID:
AT+CWJAP="WinnerMicro_WiFi","12345678","28:6d:cd:55:e5:7b"
