BREDR

BREDR is a four-byte integer stored in little-endian format, commonly used as a part of the Bluetooth protocol. It is used to exchange cryptographic keys between devices. The acronym BREDR stands for Bluetooth Reduced Energy Directed Reconnect.

BREDR is used for purposes of pairing devices on Bluetooth connections. The process involves an initial exchange
