3.2.3.Transparent AT Command
When module in transparent mode, you can use “PAT command” format to send AT command via serial
or network. If you use transparent AT command, you needn’t enter AT command mode.
Default command password is
www.usr.cn#
and user can send AT command AT+CMDPW to change password.
Take querying firmware version with default password as an example, user need send
www.usr.cn#AT+VER[0D]
([0D] represents carriage return and user must end the whole command with carriage return. It’s same as serial
AT command.).
