Receive serial data SCI notification RM46L852

A3JBNE 
I am using the LAUNCHXL2-RM46 kit

case 11U: 
 
byte = (uint8)(sciREG->RD & 0x000000FFU); 

if (g_sciTransfer_t[0U].rx_length > 0U) 
{ 
*g_sciTransfer_t[0U].rx_data = byte; 
 
g_sciTransfer_t[0U].rx_data++; 
g_sciTransfer_t[0U].rx_length--; 
si (g_sciTransfer_t[0U].rx_length == 0U) 
{ 
sciNotification(sciREG, (uint32)SCI_RX_INT); 
}
 } 


sci notification() will not be executed, because it is not known what length SCIRX will receive. How can i fix this

    Hi,

    (I know nothing about your board/mirocontroller, but fairly sure) Isn't that merely referring to the SCI or DMA hardware buffer size?  This is low-level; it is up to you to implement code to handle the high-level collection of the bytes or chunks of bytes, from multiple calls to that callback, so that they are reassembled into your actual message size (e.g. 200 chars) based on (say) a payload size or timeout or whatever you wish, since that's protocol dependent (i.e. your protocol).
