How can I exchange data using LPUART and interruption as I can find only functions HAL_UART_Transmit_IT and HAL_UART_Receive_IT? Are there similar functions for LPUART? I am using STM32WB55RG

Please include your chip number in your post.

Doesn't HAL_UART_Transmit_IT also work with LPUARTx the exact same way it works with USARTx/UARTx?

STM32WB55RG (nucleo)

@TDK​ and how can I activate the interruption for RX? Like this?__HAL_UART_ENABLE_IT(&hlpuart1,UART_IT_RXNE);

I think so, but let CubeMX generate the setup code if you are unsure. This doesn't enable the NVIC interrupt.

as far as I understood I can use any function for UART just changing the typedef to &hlpuart?

I tried this __HAL_UART_ENABLE_IT(&hlpuart1,UART_IT_RXNE); but there are some weird symbols in my rx buffer

It’s not possible to provide focused help to debug your problem with the amount of information you’ve provided.
If you need general help on using LPUART there are many examples in the repository.
