Hi Emil, Please provide the steps required to reproduce the issue, so that We can try looking into the logs and analyze the issue.

I also tried some other revisions but all seem to give the same error. /Emil 2016-12-07 4:53 GMT+00:00 G, Jaya P <jaya.p.g@xxxxxxxxx>: > Hi Emil, > > Can you try with this FW and verify.

But if I start a LE scan and then initiate a connection, it fails with the error code Connection Rejected due to Limited Resources (0x0d). If I however do it the other way around, first starting the connection attempt followed by starting scan, everything works as normal. This is clearly a bug in the firmware so I was just wondering if there were any Intel guys here willing to fix this? I've actually seen the same problem as well on a cheap Android Asus tablet having some Intel bluetooth chip in a snoop log. > > This is btmon log where it fails: > > > < HCI Command: Reset (0x03|0x0003) plen 0 > [hci0] 2238.125717 >> HCI Event: Command Complete (0x0e) plen 4 [hci0] 2238.138612 > Reset (0x03|0x0003) ncmd 2 > Status: Success (0x00) > < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > [hci0] 2238.138702 >> HCI Event: Command Complete (0x0e) plen 12 [hci0] 2238.139583 > Read Local Version Information (0x04|0x0001) ncmd 1 > Status: Success (0x00) > HCI version: Bluetooth 4.0 (0x06) - Revision 3584 (0x0e00) > LMP version: Bluetooth 4.0 (0x06) - Subversion 3584 (0x0e00) > Manufacturer: Intel Corp.
