The shift operation is higher precedence so the code is wrong and it sets of a static checker warning. But it doesn't affect real life because BT_UART_MSG_FRAME3SCOESCO_POS is zero so the shift is a no-op.
I have re-written it in normal style and with parenthesis as a cleanup and to silence the static checker warning.
