Hi all!
This may be a simple answer from many in the forum, but for me its been a struggle.
I’m able to send a request in the format of serial of 8bytes data. hence query to a RTU device.
in return the device responds via serial with 13bytes.
I can sort of read the bytes via:
if (Serial.available() > 0) {
incomingByte = Serial.read();
lcd.setCursor(1, 1); ( external I2C screen)
lcd.print(incomingByte);
}
The Question is, How can I save the 13 bytes received in order to be used later.
this is the request:
11,03,00,54,00,04,07,49
this is the response:
11,03,08,00,64,00,3E,00,0D,00,55,9C,E8
