    If the GDO0 is configured to be sync sent/received packet sent/received (IOCFG0 = 0x06) then the signal will be used in both RX and TX.

    That means that you in your application needs to keep track of what mode you are in (you should use  TXOFF_MODE = RXOFF_MODE = IDLE)

    You can have a flag called txFlag that is set to true everytime you send a STX strobe, and false every time when TX is completed.

    That way you can check this flag in you interrupt routine when something is happening on GDO0, and take action depending on what mode you where in when the  interrupt happenend.
