OK
• <ip addr>: IP address of Stations to which ESP32 SoftAP is connected.
• <mac>: MAC address of Stations to which ESP32 SoftAP is connected.
This command cannot get a static IP. It only works when both DHCPs of the ESP32
SoftAP, and of the Station to which ESP32 is connected, are enabled.
Query Command:
AT+CWDHCP?
+CWDHCP:<enable>
OK
<enable>: DHCP disabled or enabled now?
• Bit0:
‣ 0: Station DHCP is disabled.
‣ 1: Station DHCP is enabled.
• Bit1:
‣ 0: SoftAP DHCP is disabled.
‣ 1: SoftAP DHCP is enabled.
The configuration changes will be stored in the NVS area.

This set command interacts with static-IP-related AT commands (AT+CIPSTA-related
•
and AT+CIPAP-related commands):
‣ If DHCP is enabled, static IP will be disabled;
‣ If static IP is enabled, DHCP will be disabled;
‣ Whether it is DHCP or static IP that is enabled depends on the last configuration.
AT+CWDHCP=1,1
Enable Station DHCP. If the last DHCP mode is 2, then the current DHCP mode will be 3.
AT+CWDHCP=0,2
Disable SoftAP DHCP. If the last DHCP mode is 3, then the current DHCP mode will be 1.
