The topic describes how to customize a WPx5xx UART port so it can be configured as an application serial port.

Syntax

The syntax is:

AT!MAPUART=a,b

Where

• a is the service type
• b is the UART number, either 1 or 2.

Here's a code sample setting 17 for the service type and 1 for the UART number:

AT!MAPUART=17,1

Reboot your target after running the command.

Run AT!MAPUART? to check the config settings.

Service Type

The current AT command spec defines the service as:

Service to map to UART: 0: UART disabled 1: AT Command service 2: Diagnostic Message service 3: Reserved 4: NMEA service 5-15: Reserved 16: Linux Console 17: Customer Linux application
