Hi,

Is there a standard ordering of the bytes in a bluetooth address?

On my linux box (2.6.12.1):

# hcitool dev 
Devices:
        hci0    00:02:72:C0:7C:2B

But when my phone (Sony Ericsson K800i) discovers my server, I get this address for the server:

2B7CC0720200

This is from the Java bluetooth api on the device. And yes, I have to reverse that address in order to connect to the server.

Thanks
Per Thomas

the Bluetooth device address (BD_ADDR for short) is an IEEE address and it is always transmitted in reverse order.
