Hi Pavan, I am aware of this flag and have unset this to ensure that sockets can be opened by hcid. But, I am still struggling with how to bring up hcid. By the way, can you share the init.rc file and the hcid source you are running. It seems you also had certain problems earlier.
Since yesterday, I have been able to open the socket, but I am now stuck on - hcid[681]: Unable to get the control socket for 'bluetooth' Were you able to resolve this one? I also saw that there is no Bluetooth entry in /dev/socket. What to do now?
