Because the way the ringbuffer works it's not possible to get the underlying buffer in the RX IRQ callback because then ATParser will miss characters. By adding the character as a parameter to the RX callback you can get the data in the callback, and ATParser will not miss anything (because you can implement another independent buffer).
