Hi Jack,
| Sorry to keep asking hciemu related question. The reason I like
| hciemu so much is not only I am poor :-) , but also I was supposed
| to set up a virtual environment of multiple piconets, so my team
| members can play around with some scatternet routing stuff. I've seen
| someone from this list achieved that. Now, I am following the Pan
| Howto, but I have some problems:
|
| 1. After running
|
| #pand -s -r GN -i 7F:00:00:01:00:0A #pand -i 7F:00:00:01:00:0B -c
| 7F:00:00:01:00:0A
|
| I am hoping 7F:00:00:01:00:0A to be GN, and 7F:00:00:01:00:0B to be
| PANU, but when I run pand -l, I got the following:
|
| bnep1 7F:00:00:01:00:0B GN bnep0 7F:00:00:01:00:0A PANU
|
| So, it seems 7F:00:00:01:00:0B being GN
|
| 2. I cannot add bnepX to pan0 using brctl, although I can add my eth0
| to it. After running:
|
| #brctl addif pan0 bnep0
|
| I got:
|
| can't add bnep0 to bridge pan0: Cannot assign requested address
Besides possible other problems of PAN operation with hciemu (that I'm
not aware of), you'll definitely get into trouble using BT device
addresses that start with '7F'. Bits 0 and 1 of the most significant
byte of the device address have a special significance:
One of them determines whether the address is a unicast or multicast
(when set) address. The other one determines whether the address has a
local (when set) or global scope. BT device addresses conform with the
IEEE 802 MAC address specification (you may want to do a web search on
this), where this is defined. With either one set, you'll encounter
trouble with the bridging code (and possibly the BlueZ PAN code?).
Make sure you use addresses where these bits are not set.
Hope this helps,
Michael
