Android Question Astream_NewData

I am working with B4a and with this library for some times, they are perfect tools for me to create a cnc marking machine.
What i can not figure out is;
For my application i send more than 1500 bytes to a micro controller.
What i want to impliment is the reading process into a for loop that sends the data to micro controller.
So after sending 500 byte it will wait the signal from microcontroller to go on.
When i add the line "ReceivedByte = BytesToString(Buffer, 0, Buffer.Length, "UTF8")" into the for loop
it gives me the error that "undeclared variable buffer is used before assigned any value".
Would you please tell me the proper way to use it.
