[CentOS] Bluetooth 4.0 with chip BCM20702A0 on CentOS6.4

Hi All,

  I bought a USB Bluetooth dongle.

However, it's not working for me. Please help, how to debug and get more
information as I can not see any error or warning message from system log
message.

I checked http://thread.gmane.org/gmane.linux.bluez.kernel/22183/focus=22211,
however, also find another page
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.3_Release_Notes/index.html
said
already support BCM20702A0.

Please help, thank you.

You can try with newer kernels from ElRepo 
(http://elrepo.org/tiki/tiki-index.php) that have compatible API's with 
EL6. look for elrepo-kernel section on main page. Currently there are 
kernels 3.0.83-1 and 3.9.7-1. But do note that those are third party 
kernels, even though ElRepo is safe third party repository.
