Cause of "access denied" when attempting to connect?

[mdlieder]

Hello! A few of our users are encountering access denied (WCL_E_BLUETOOTH_ACCESS_DENIED) errors when attempting to connect to a wclRfCommClient device, both Windows 7 users and Windows 10 1607 users. Do you happen to know potential causes of that error?

Thanks!

Hello,

This error usualy means that device requires pairing before connecting. Also it may appear when PC has device in paired devices list but device itself was unpaired with PC (PC is not in paired devices list).
