Q2686 UART receive buffer size is limit only 56?

char array is not a string if does not have null char (‘\0’).

To be more precise, ‘C’ string handling functions rely upon a NUL character to terminate strings.

You didn’t Preview your post - did you?

You forgot the ‘Code’ tags!

You don’t really gain anything by writing ‘\0’ - you might as well just write a zero:

if( atwritecnt>90 )
  {
     Rawdata[atwritecnt] = 0; // NUL terminator

     adl_atSendResponsePort( ADL_AT_RSP, uart1_port, Rawdata );
     adl_atSendResponsePort( ADL_AT_RSP, uart1_port, "\n" );
     atwritecnt=0;
  }

Note that “NUL” (with a single ‘L’) is the name give to the code value zero by ASCII - not to be confused with the ‘C’ NULL pointer value…
