Figure 85. Serial AT command test
9.2. Network AT Command
In transparent mode, user can send “command password+AT command” to query and configure
parameters. Network AT commands are used to query or configure the parameters from remote server, which is
similar to serial AT commands. For example, we can send “www.usr.cn#AT+VER” to query the firmware version
from server side (there is a line feed after the command).
