UART not receiving while transmitting with another

[Omar-AbdulQadir]

Hello,

I am using STM32F407 Transmitting some data over UART and Receiving the same data with another in INT on the MCU.

The problem is that the receiving side gets only the first byte even when switching sides the receiving side still receives only the first byte.

I think that the HAL stops receiving data on all UARTS while transmitting.

Show your code.

If you want to receive UART data while also sending, you will need to use IT or DMA functions to receive.
