RE: [bluetooth-dev] RE: attempting service discovery



Hello,

Try to disable the master/slave switching at the server (in /etc/bt.conf, change the msswitch to false).
I've seen this behaviour too with some vendors and disabling the M/S switch may help. However the card
seems to support it as it really should send you a role_change event telling you that it couldn't do it.

Best Regards
Anders Johansson
