Subject: [Bluez-users] role change not allowed when connecting with PAND

Hi,

When I run

pand --connect XXXX --persist

and my server runs

pand --listen --role NAP

and hciconfig -a on the client shows (Had to type this over)

link policy : RSWITCH, HOLD PARK SNIFF
link mode : SLAVE ACCEPT
Features : 0xff 0xff 0x05 0x00

and on the server it shows

you still have security mode 3 on one side. Disable the "auth" and/or
"encrypt" and try again. Don't set the master link mode on device level,
because pand has a --master for this case.

Marcel
