Dear Marcel,

thanks for your reply, 

It is same as the information of hcid.conf  that the command " hciconfig -a" display the attribute in PC linux,
But I have a try in embedded linux, it is not same as the information of hcid.conf, although I call "hcid -f hcid.conf ", it looks like calling "hcid" command has no effect
How to let the attribute be same as that listing in hcid.conf? 
Thanks

Best regards,
Leiyu
