Dear Intel_Peter,
It worked!! Thank you so much for your advice :)
I successfully read the data received in the file and printed out the contents of that file in the Serial Monitor in Arduino.
Now I am looking to improve my data transfer so that it will be in sync with the data sent by Bluno. Is there a way for intel Galileo to send a request to Bluno so that every time that request is sent, Bluno will perform a data transfer. How can I go about achieving this?
