I found the tutorial of client (android) and server (pc) bluetooth tutorial from here.
But my question is about the UUID.
Is that okay if we define it randomly without the proper format? Because I heard UUID is generally for ID for each devices just like IP address used right?
For example like this, instead of the following code:
I define my own UUID
Is it okay? I mean is it if i tested on both android device using the above code, they could communicate each other?
