How to disconnect and prevent connection from btstack SPP server?

[Ho Tony]

Matthias,

Situation 1:

  I use the btstack setup a SPP server, and I want the SPP server disconnect the SPP connection and prevent connected by others in some status, I used the rfcomm_disconnect and gap_connectable_control(0), but others still can connect this SPP server, what's wrong?

Situation 2:

Also, some time after disconnection from SPP server, I want to enable the connection, so I call the gap_connectable_control(1), but others cann't scan the SPP server now. Any tips?

I use the CSR8510 and the RPI3 built-in Controller.

If you call gap_connectable_control(0), BTstack will disable Page Scan and other devices cannot connect to it.
Please have a look at the HCI Trace and check that BTstack sends a HCI Write Scan Enable Command with the correct scan type.

To find an unknown device, the inquiry process is used. To be found by another is the inquiry scan process. You can enable/disable inquiry scan with gap_discoverable_control(0/1)
