[GoogleCodeExporter]

Which device (manufacturer, type)?
HTC desire (Rooted)

Which firmware is installed?

HBOOT - 0.80.0000
RADIO - 4.06.00.02_2
FIRMWARE - 2.1-UPDATE1
KERNEL - 2.6.29-82821FB5

What version of wireless tether are you using?

tested against 2.02 and 2.05 (because the howto said "latest")
using 2.02 as nominal target

What steps will reproduce the problem?

1. created android.tether in root of sdcard 
2. copied in and renamed file from evo
3. rebooted (just in case!)
4. re-installed 2.02 (downloaded via google to pc and pushed not market) 
5. started wireless tether
6. pressed menu selected setup
7. scrolled down to change lan
8. selected 192.168.0.3/24
9. pressed back button
10. scrolled up to top
11. ticked Use bluetooth 
12. ticked discoverable
13. pressed back
14. started tethering 
15. accepted Bluetooth permission (DISCOVERABLE) request
16. started pairing process on Win XP Sp3 netbook (EEE900 dual boot) 
17. scanned for bluetooth devices 
18. found phone & paired with netbook
19. went to bluetooth desktop icon
20. selected "join a PAN" 
21. ensured desire was still in discoverable state - 55 seconds to go
21. scanned for PAN capable devices - wifes phone found, desire not! 
22. repeated steps 16-22 on prefered OS (ubuntu netbook remix (lucid)
23. observed same issue.

What is the expected output? What do you see instead?

Expect Desire to identify itself to tether PC as being a PAN capable device 

Actually saw nothing reported back from phone 

Please provide any additional information below.

bluetooth device is a HAMA micro USB dongle.

bluetooth PAN still works flawlessly with HTC raphael (win mob 6.1) so ruling 
out the PC end at this time.

more than happy to provide traces etc genuinely don't want to have to go back 
to wm6 device but bluetooth PAN is mission critcal here as customers laptop has 
no wifi (custom PCI_E card in its place) not allowed to connect USB device, yet 
expected to get corporate mail using bluetooth PAN (go figure ??) ;-)

DHCP issue found to be zero byte file in /sdcard/android.tether

re-copied the broadcomm driver file across 

NAT not working but still looking at that

I can reproduce this on Windows 7 as well, using the integrated Bluetooth card 
of my notebook. Software stack is Windows 7 native with Widcomm/Broadcom 
additions.
