Serial lib v1.21 for bluetooth 3.0
Edit: “USB 3.0" in the title should be "bluetooth 3.0"
Hello,
I tried a bluetooth module for testing. The module is 3.0. The connection is much faster than my another 2.0 module in a demo written in Java.
When I use the "bluetooth" sample in tutorial to test the module, the application stopped on an exception. It was OK when I use the chat sample from Google.
Any advice? Is bluetooth 3.0 special?

The error happens only when I tried to send 4th byte to "bluetooth" app from a serial console on PC. i.e. the app is receiving. The app didn't crash during first 3 bytes while nothing was show up. The "Send" function also didn't work but didn't crash the app either.
