Bluetooth. Pairing using PIN. How to activate it?

  • Hi all,

    We have embedded system running with blueZ5.50 and Qt5.12.2. In our application we are running SPP server and from other side we have now written in Java simple SPP client running on Android smartphone. We can connect from smartphone to device and transfer data. That works fine. But the connection running without requesting of PIN confirmation. In Bluetooth SSP terms it "Just works". Is it possible (if yes then how?) to change in Qt application the confirmation from "Just works" to "Numeric comparison".

    Thank you for advise,
