I'm going to run a ping-pong example with two p-nucleo-lrwan1. How do I separate the master from the slave? Terminal uses 'tera Term'.

Yes. I don't see the Initialization code.Can you show me an example of a Initialization code?

void USART4_Init(void){ static UART_HandleTypeDef huart4; GPIO_InitTypeDef GPIO_InitStruct; __HAL_RCC_USART4_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_DMA1_CLK_ENABLE(); /* UART TX/RX GPIO pin configuration */ GPIO_InitStruct.Pin ...

5 to 6 lines of code you gave me __USART4_CLK_ENABLE(); __GPIOC_CLK_ENABLE();Is this right? This results in an error. __HAL_RCC_USART4_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE();This won't cause an error.Is this right?
