Hi,

How works the PinCode on Classic BT and how in BLE?

I fond that the pin in BT classic can bo hardcoded, but what is with BLE ?

What is the encryption in SPPLE_demo?

Regards,

David.

    Hi David,

     

    By default the I/O Capabilities

    For LE is No Input/Output. And for BR/EDR is Display Yes/No.

    So you will not see any key request for LE, it Invokes “Just Works”

     

    You can change the I/O Capabilities as below so that you will be asked to enter the “LEPasskeyResponse”

    SPP+LE>ChangePairingParameters 4

    LE:     I/O Capabilities: Keyboard/Display, MITM: TRUE.

    BR/EDR: I/O Capabilities: Display Yes/No, MITM: TRUE.

     

    SPPLE_demo has encryption.
