Hoping someone who has seen this happen can help. I have a BlueSMiRF HID and Arduino Leonardo setup to mimic mouse movements (gaming). Connection is to an iMac OSX 10.9 and a Macbook Pro OSX 10.9 with these results on both:
Everything works great for exactly 5 seconds, then the connection is disrupted (no mouse movement, brief red LED on bluesmirf) and then it reconnects.
I've been trying different combinations in the BlueSMiRF configuration, but everything that works at all has the same problem.
The fact that it's exactly every 5 seconds makes me think I'm missing something fixable.
