If required, an AT+CMD can be used to change the pin connection for UART1 in accordance with the
Pin Mux Configuration as shown in
Figure 5 .
For example, the following AT+CMD can be used to change the Pin Mux configuration to use
GPIOA_2 for UART1 TX and GPIOA_3 for UART1 RX:
AT+AWS=SET NV_PIN_BMUX BMUX_UART1d
// GPIOA_2 and GPIOA_3 for UART1
