Account cancelled 2017-03-25 08:51:51 1388 Views1 Replies I wrote a simple code that send via bluetooth a string in the loop() rountine using Serial.print, but no data is sent until I connect Bluno to pc using USB port and open a terminal like PuTTY.
How can I send data via bluetooth without a pc connected to the board?
