Uart Callback function only getting two bytes

Question

Hello all, 
 Does anyone know why the callback function only gets the first two chars of a string? I thought it was suppose to trigger off each incoming byte.

Hello Cory, 
 Thank you for reaching out Renesas Engineering Community. 
 First of all as already mentioned we would like to share with us some sample code to check what might is going wrong in your project. Also please provide us the part number of the MCU you are using. 
 Regarding your issue, please let me attach for you an example project, I have created to replicate your issue on RA2L1. I am sending from a Serial Terminal the word hello as you do. 
 
 In my sample code I have a buffer which has a total size of 15 bytes. As soon as the whole buffer fills my code hits a breakpoint. 
 As you can see the characters I am sending have been received with no issues. 
 
 As you in my code I am not calling the Read API and the buffer fills every time I get a UART_EVENT_RX_CHAR event and I receive one character per time. 
 Hope this will help you proceed. 
 
 Best Regards, 
 IK
