Thank you, i will add this line. But this is not about my problem. "\n" is the ending character after that new data must start to received. Somehow i managed to work this code but now it is working only when i am debugging. Any ideas ?

Maybe check for overflow and reduce the Rx array size from 100 to (say) 4 just to test:

        if ((buffer[length] == '\n') || (length >= MAX_RX_BUFFER_SIZE-1))

Also if just a lf '\n' is received length will have the value 0 which might confuse uart_callback()
