Ethernet AT Commands

Note

This command set is automatically activated when Ethernet functionality is enabled, requiring no additional configuration.

AT+ETHSTART

Starts the Ethernet interface and brings up the network with the specified addressing mode.

AT+ETHSTART=<mode>

Success response:

OK

Error response:

ERROR:<error_no>

<mode>:

Addressing mode

0: DHCP Client, obtain IP address from a DHCP server
1: DHCP Server, act as a DHCP server (requires a static IP configured via AT+ETHIP)
2: Static IP, use the static IP configured via AT+ETHIP

Note

When <mode> is 1 or 2, a static IP must be configured with AT+ETHIP beforehand.
If the Ethernet interface has already been started, the new mode takes effect on the next link-up event.

Configures static IPv4 address and related network parameters for the Ethernet interface.

AT+ETHIP=<store_flag>,<ip>[,<gateway>,<netmask>]

Success response:

OK

Error response:

ERROR:<error_no>

<store_flag>:

Configuration storage flag

<ip>:

IPv4 address string (e.g., 192.168.1.100)

<gateway>:

Gateway address

<netmask>:

Subnet mask

Note

When store_flag=0 or 1, configuration takes effect immediately after command execution.
store_flag=2 only clears flash storage without affecting current runtime configuration.
Configuration results can be verified using the AT+WLSTATE command.
