Hello,
i've followed many tutorial to try to get UART with interrupt working on my stm32l476rg (nucleo board) :
at the main.c, before while(1) loop :
HAL_UART_Transmit_IT(&huart4, (uint8_t *)welcome_str,sizeof(welcome_str));
this doesn't work, but in polling mode, it's working :
HAL_UART_Transmit(&huart4, (uint8_t *)welcome_str,sizeof(welcome_str),100);
i'm using hc-06 bluetooth dongle, and receiving it on android Phone, it should be able to receive interrupt without any problem...?
what i'm missing here ? any triggering stuff or ..?
thank you
