Question in bluetooth security

[eng_electric]

Hello all

Is it possible for a device to send a text using RFCOMM with another device without asking them for authentication nor pairing? If not, is there a way to bypass this security issue?

Thank you

There is no way to by pass the bluetooth security queries (or passkeys) if the devices have not been paired earlier. (However, once paired, setting the device as authorized, can avoid those queries, you might know that)
