W630 supports search in-LAN. When W630 is connected to a wireless router, users can obtain the IP address of the

Search process:
1. On another device in the LAN, the search command "www.usr.cn" is sent via UDP broadcast (broadcast address:

address, and send +ok (no return) through UDP to enter network AT instruction mode.
If the W630 doesn

t receive the setup command within 30 seconds after entering the configuration mode, it will exit
the configuration mode. The user needs to resend the search command word and enter the configuration mode.
3. Users can set and read the parameters/states by sending network AT commands (upper case) to the port. The net
AT commands are in the same format with serial AT commands.
Note: Search tools and W630 must be in the same LAN. If multiple STAs are connected to a router, the computer
