Overview

A bluetooth address (bdaddr_t) is encoded in little endan, 6 bytes in total. When such an address is written as a string, it is normally written in big endian, where each byte is encoded in hex and colon as separator for each byte. For example, the address 08:09:0a:0b:0c:0d is encoded as the bytes 0x0d, 0x0c, 0x0b, 0x0a, 0x09, 0x08.
