Serial1.available()

Hi,

I have a new problem.
It looks like the Serial1.avalable() only outputs a 1 if data has arrived. Not the number of bytes in the buffer.
Furthermore, not all bytes are read from the buffer.


/*** Don't worry, the normal Arduino setup() and loop() are below this block! ***/

/* LMU uninitialised data */
StartOfUninitialised_LMURam_Variables
/* Put your LMU RAM fast access variables that have no initial values here e.g. uint32 LMU_var; */
EndOfUninitialised_LMURam_Variables

/* LMU uninitialised data */
StartOfInitialised_LMURam_Variables
/* Put your LMU RAM fast access variables that have an initial value here e.g. uint32 LMU_var_init = 1; */
EndOfInitialised_LMURam_Variables

/* If you do not care where variables end up, declare them here! */

/*** Core 0 ***/
void setup()
{
 // put your setup code for core 0 here, to run once:
 Serial1.begin(19200);
 SerialASC.begin(19200);
 Serial1.setTimeout(5000);
}


void loop()
{
 // put your main code for core 0 here, to run repeatedly:
 if (Serial1.available())
 {
   SerialASC.print("Buffersize=");
   SerialASC.println(Serial1.available());
   
   char ch = Serial1.read();
   SerialASC.println(ch);
 }

}

If you send one Byte only, everything seems OK.
But if you send e.g. 10 bytes, then only a few are read. It is only when new bytes are sent that the rest is read.
