I've been using my Twiddler for a few weeks, practicing both on my phone and laptop. Yesterday it disconnected from my phone while I was typing. I had tremendous difficulty getting it to re-pair, and once I did, the connection only lasted a short while. I tried again with my laptop, but could not get it to connect again there either. It won't pair with my desktop at all, and actually caused blueman-manager to crash.
The N+S R000 reset of pairing doesn't seem to do anything - there is no reaction from the LED. I had expected it would blink as if searching for a new device to connect to.
The power seems fine. When I plug in via usb, it currently is reporting vcc=96.
What else should I be looking at?
