Im following the "4.10Pair two NINA-B1 using Out-of-Band security mode" use case example of the "NINA-B1_GettingStarted" document.
After setting out of band security on both BLE devices (AT+UBTSM=6,0) and reseting them (AT&W; AT+CPWROFF), I generate a random OOB Temporary Key on the peripheral device (AT+UBTOTK=0), but the central device can still pair to the peripheral without entering the key with a common pairing command (AT+UDCP=sps://<peripheral_dev_address>p).
Moreover, if I try to pair using the command described on the document adding the key (code bellow) the pairing is refused.
Can anyone help solving this? Thanks.
