Hi everyone!
I'm new here and I'm trying to find a library or some code that can help me doing this: When someone is near to my Arduino and they have their Bluetooth On, my Arduino will send them an image (or at least some Text). So, pratically, I need to send an image file from my Arduino to a smartphone bluetooth that is active and public.
I found only a library that resolve the inverse problem (the smartphones send a file to the "main station", but it cannot reply).
Can someone please help me? Thanks a lot!
