Now the default shipping configuration of the D3 serial port is used as a transparent serial port. How can I need to modify it for AT command interaction?

The default shipping configuration of the D3 serial port is used as a transparent serial port. If the customer needs to modify it for AT command interaction, the internal AT command can be sent under the webserver to modify the role of the D3 serial port. The specific steps are as follows:

1. Log in to the debug page of the web server

2. Enter the “AT^CONFIG=1,0,0” command in the “At Command” column and the “OK” prompt will be returned if successful

3. Enter “AT^CONFIG?” command in the “At Command” column to check again to confirm whether the configuration is successful

Note:

1. After the above modification, you need to restart the power to take effect
2. If you need to modify D3 to be a transparent serial port again, just replace the above AT command with “AT^CONFIG=0,0,0”.
