[ESP32 Only] Ethernet AT Commands¶

[ESP32 Only] AT+CIPETHMAC—Sets the MAC Address of the ESP32 Ethernet¶

Query Command:

AT+CIPETHMAC?
Function: to obtain the MAC address of the ESP32 Ethernet.

Response:

+CIPETHMAC:<mac>
OK

Set Command:

AT+CIPETHMAC =<mac>
Function: to set the MAC address of the ESP32 Ethernet.

Response:

OK

Parameters:

Notes:

The configuration changes will be saved in the NVS area if AT+SYSSTORE=1.
The MAC address of ESP32 SoftAP is different from that of the ESP32 Station. Please make sure that you do not set the same MAC address for both of them.
Bit 0 of the ESP32 MAC address CANNOT be 1.
- For example, a MAC address can be “1a:…” but not “15:…”.
FF:FF:FF:FF:FF:FF and 00:00:00:00:00:00 are invalid MAC and cannot be set.

Example:

AT+CIPETHMAC ="1a:fe:35:98:d4:7b"

Query Command:

AT+CIPETH?
Function: to obtain the IP address of the ESP32 Ethernet.
Notice: Only after calling esp_at_eth_cmd_regist can its IP address be queried.

Response:

+CIPETH:ip:<ip>
+CIPETH:gateway:<gateway>
+CIPETH:netmask:<netmask>
OK

Set Command:

AT+CIPETH=<ip>[,<gateway>,<netmask>]
Function: to set the IP address of the ESP32 Ethernet.

Response:

OK

Parameters:

Notes:

The configuration changes will be saved in the NVS area if AT+SYSSTORE=1.
The set command interacts with DHCP-related AT commands (AT+CWDHCP-related commands):
- If static IP is enabled, DHCP will be disabled;
- If DHCP is enabled, static IP will be disabled;
- Whether it is DHCP or static IP that is enabled depends on the last configuration.

Example:

AT+CIPETH="192.168.6.100","192.168.6.1","255.255.255.0"
