Hi,
I'm using STM32F401RE UART with DMA to receive a continuous stream of data and send over BLE. I am facing issue when that DMA buffer full interrupt stops working as I attach to stream of data. It works perfectly fine when I give data in chunks (20 or 1023 bytes) through PC comm port in non-continuous manner. I am trying to work in debugger mode and it works with PC COM port and hits breakpoints in call back function but not on stream of data coming from module. I check the data streaming module its working fine. I am using in buffer of size 20 and 1023 bytes.
Kindly let me know how to resolve the issue.
Many many thanks.
Kind Regards, Ghalib
