I have downloaded the software from the below github link Code , i want data to be sent to serial port, the board i am using is Wio- E5 mini, but i am concerned with the serial port initialization, as per the website the below are the ports used

PA2/PA3 for nucleo, PB6/PB7 for Wio-E5 mini

when i have checked the serial code in the file stm32wlxx_LoRa_E5_mini.h

#define COM1_UART                             LPUART1
#define COM1_CLK_ENABLE()                     __HAL_RCC_LPUART1_CLK_ENABLE()
#define COM1_CLK_DISABLE()                    __HAL_RCC_LPUART1_CLK_DISABLE()

#define COM1_TX_PIN                           GPIO_PIN_2
#define COM1_TX_GPIO_PORT                     GPIOA
#define COM1_TX_GPIO_CLK_ENABLE()             __HAL_RCC_GPIOA_CLK_ENABLE()
#define COM1_TX_GPIO_CLK_DISABLE()            __HAL_RCC_GPIOA_CLK_DISABLE()
#define COM1_TX_AF                            GPIO_AF8_LPUART1

#define COM1_RX_PIN                           GPIO_PIN_3
#define COM1_RX_GPIO_PORT                     GPIOA
#define COM1_RX_GPIO_CLK_ENABLE()             __HAL_RCC_GPIOA_CLK_ENABLE()
#define COM1_RX_GPIO_CLK_DISABLE()            __HAL_RCC_GPIOA_CLK_DISABLE()
#define COM1_RX_AF                            GPIO_AF8_LPUART1
#define COM_POLL_TIMEOUT                      1000

I see PortB6 and B7 are not initialized they are still using the PA2, PA3. Please advise me if i missing anything?

I used PB6 and PB7 i can see the messages on the serial terminal.
