Hi everyone!I've been trying to implement UART reception using LL library in polling mode. The code below is what handles the reception: uint8_t LL_USART_Receive_Byte(USART_TypeDef *USARTx) { // Wait for Read Data Register is not empty while (!LL_U...

I see. Is this because of my test set up using various UARTs in the same MCU or it will be the same with UART communication between a STM32 & a modem SIM7070G?

Why am I lucky? It is not suposed to work? I've seen the DMA approach, but I sticked to the polling mode solution (but it seems not to be ideal).

I don't really want to keep this interconnection, I set it up as a test in order to make sure how to implement UART Tx & Rx in polling mode using LL drivers. The main goal is to substitute the HAL functions HAL_UART_Transmit(...) & HAL_UART_Receive(....
