Hi All, I have a HoG device, first time I pair and connect work fine... in the next reboot while connecting I saw multiple disconnection, after looking into hcidump I found that disconnection was due to authentication failure. After multiple attempts (which it does) one attempt will succeed to establish the connection. I also found that while initializing adapter stored link keys are being deleted. is this the reason for Authentication failure ? > HCI Event: Command Complete (0x0e) plen 14 Read Local Extended Features (0x04|0x0004) ncmd 1 status 0x00 page 1 max 1 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 < HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7 bdaddr 00:00:00:00:00:00 all 1 Please let me know your thoughts on it..
