o bit 0: PMF capable, advertizes support for protected
management frame. Device will prefer to connect in PMF mode
if other device also advertizes PMF capability.
o bit 1: PMF required, advertizes that protected management
frame is required. Device will not associate to non-PMF
capable devices.
• <error code>: (for reference only)
o 1: connection timeout.
o 2: wrong password.
o 3: cannot find the target AP.
o 4: connection failed.
o others: unknown error occurred.
Notes
• The configuration changes will be saved in the NVS area
if AT+SYSSTORE=1.
• This command requires Station mode to be enabled.
• The parameter <reconn_interval> of this command is the same
as <interval_second> of the command AT+CWRECONNCFG. Therefore,
if you omit <reconn_interval> when running this command, the interval
between Wi-Fi reconnections will use the default value 1.
• If the <ssid> and <password> parameter are omitted, AT will use the last
configuration.
• Execute command has the same maximum timeout to setup command.
The default value is 15 seconds, but you can change it by setting the
parameter <jap_timeout> .
• To get an IPv6 address, you need to set AT+CIPV6=1.
• Response OK means that the IPv4 network is ready, but not the IPv6
network. At present, ESP-AT is mainly based on IPv4 network,
supplemented by IPv6 network.
• WIFI GOT IPv6 LL represents that the linklocal IPv6 address has been
obtained. This address is calculated locally through EUI-64 and does not
require the participation of the AP. Because of the parallel timing, this print
may be before or after OK .
• WIFI GOT IPv6 GL represents that the global IPv6 address has been
obtained. This address is combined by the prefix issued by AP and the
suffix calculated internally, which requires the participation of the AP.
