[Bluez-users] problem decoding Link_Policy_Settings parameter

[Bluez-users] problem decoding Link_Policy_Settings parameter

[soraberri]

Hi, how are you there?
I hope you could help me with this stoping problem:

let's say I do 'hcitool cc --role=m 00:10:60:A5:8F:8A'
and now, the output in hcidump is the following:

< HCI Command: Create Connection (0x01|0x0005) plen 13
   8A 8F A5 60 10 00 18 CC 02 00 00 00 00
 > HCI Event: Command Status (0x0f) plen 4
   00 01 05 04
 > HCI Event: Connect Complete (0x03) plen 11
   00 29 00 8A 8F A5 60 10 00 01 00
< HCI Command: Write Link Policy Settings (0x02|0x000d) plen 4
   29 00 0F 00
 > HCI Event: Command Complete (0x0e) plen 6
   01 0D 08 00 29 00
 > HCI Event: Page Scan Repetition Mode Change (0x20) plen 7
   8A 8F A5 60 10 00 01
 > HCI Event: Max Slots Change (0x1b) plen 3
   29 00 05


My problem is I cannot render an interpretation of the Write Link Policy 
Settings Command, because I read 0x000F as the Link_Policy_Settings 
parameter, and by looking at the bluetooth specification this value is 
not allowed (or at least it is not defined), so what a strange way of 
telling the device to stay master!

thanks all (especially Marcel cause none post of mine has miss one of 
his answers)

the connection handle is 41 and the link policy is 15. This means that
role switch, hold mode, sniff mode and park state are enabled. The math
is quite simple:

	1 + 2 + 4 + 8 = 15

The link policy is a bit oriented value.

You are welcome.
