Dial-up Networking Via Bluetooth Under WM5 AKU3 / WM6: WORKING at last!! A MUST!!!

[Menneisyys]

Anyone having read my article New dial-up networking model of the WM5 AKU3 – a must if you use your WM phones as modems knows WM5 AKU3 (and, of course, WM6) has dramatically changed the way dial-up networking is handled – not necessarily in the good direction. (Please DO read the article if you don’t have a clue what I’m referring to and you would ever want to use your Windows Mobile handheld as a cellular modem!)

Microsoft, so far, haven’t really done anything to the problem, except for publishing an article (also discussed for example HERE). Therefore, hackers needed to concentrate their forces on solving the problem. After the first failed attempts (for example mine, as is explained in the first-linked article), at last, some excellent XDA-Developers folks have managed to enable this feature with a comparatively easy-to-do hack. I’ve developed the hack further, making it compatible with several handheld models and ROM versions (the previous version available at XDA-Developers doesn’t support the Universal, Wizard and, probably, several other models because it doesn’t do any forced Registry import – it might only be compatible with the P3600.)

The hack makes it possible to use most WM5 AKU3 / WM6 devices in the traditional (pre-WM5 AKU3) DUN dial-up method, in addition to the new, in WM5 AKU3 introduced Internet Sharing.

This means you can use BOTH technologies and can have the advantages of BOTH approaches. With the “traditional” DUN dial-up, you still have the freedom of NOT having to manually start / reconnect Internet Sharing AND the ability to use clients not supporting the BT Personal Area Network (PAN) profile required by the new Internet Sharing. And, as Internet Sharing is still supported, you can still have a real internet sharing approach, making it possible to use the Internet on both the Windows Mobile device acting as a modem and the client that connects to it (and can still have the other goodies Internet Sharing also offers: for example, the accessibility of the phone even with an ongoing Internet session.)

Again, it’s almost impossible to emphasize how important, how revolutional this hack is! If you’ve EVER tried to use your WM5 AKU3 / WM6 Windows Mobile phone as a modem you know Internet Sharing can be a REAL pain in the back, particularly if the client you’d like to use it from doesn’t support BT PAN.

Installation

Import THIS registry import file (via, say, the brand new, EXCELLENT desktop-side Registry editor of SOTI’s Pocket Controller 6) and copy the contents of THIS file to the \Windows directory of your Windows Mobile device. Soft reset your device and voliá: after this, clients discovering the Bluetooth services your device provides will also see it offering the DUN service (in addition to the PAN one) as can also be seen in HERE.

After this, everything will work just great – as in the pre-AKU3 days. Follow for example THIS tutorial on using DUN modems if you don’t know how it’s done.

Problems

1. It’s incompatible with some HTC Wizard ROM versions, namely, the official AKU 3.3 T-Mobile ROM – see THIS. It, however, has no problems with mfrazzz's XDA Mobile 6 Release 2a Full at all.
2. It seems it’s incompatible with WM6 MS Smartphones (Windows Mobile Standard). I’ve tested this on my HTC Vox (S710).

Compatibility

In my tests, it worked just great on my HTC Universal (WM6 Midget version) and HTC Wizard (WM6 mfrazzz version 2a). A lot of people have reported other success stories; for example, with the AKU3 HTC Trinity (P3600).

Verdict

Again and again: if you EVER plan to use your handheld as a modem, this hack is a MUST!

I have verified that this hack works on XDA6R2a. I encourage all to implement it. I have a few cheap $5 bluetooth dongles that refuse to use internet sharing because they all have the same mac id (11:11:11:11:11:11)....but they will connect fine using bluetooth dun which doesn't care about the mac id....my linux laptop was able to connect fine using Bluetooth DUN and my desktop which has a more expensive bluetooth dongle (translation: Not a cheap chinese copy) was able to still use internet sharing with no problem.

For rom cookers..the exe and both dll's can be upx'd and get roughly a 50% compression rate. I've tested the compressed files and they still work fine. For those installing in their existing rom and wanting to save space, make sure you compress before you install the registry and reboot as your two dll's will be in use after that.

This will be built into XDA Mobile 6 Release 3 for the Wizard (in Beta now and testing this feature and the other new features in this rom). Thanks for providing this info!

UPDATE (07/29/2007): I've tried to extract the DUN-related files from my WM5 AKU3 HTC Oxygen (s310) smartphone and put them on my WM6 HTC Vox (they are available HERE; I've also provided two Registry import files in the archive. The first, SPRegImp.reg, contains the original S310 Registry contents; the second, SPRegImp2.reg, has a much bigger HKLM\SOFTWARE\ Microsoft\ATCIUI\ Connections section).

Unfortunately, while, as opposed to the original case of trying to apply the PPC files, where not even the DUN service could be discovered, it seems it doesn't work: while the DUN service is already visible (as opposed to the original case using the PPC files), on my Vox, connection attempts fail with the same message as not importing the (original) Registry file on the Pocket PC.

I continue playing with the hack; hope I manage to achieve something. I still give you the extracted files so that you can also experiment with them. It MIGHT be working on your non-Vox Smartphohe.

I followed the istructions of first post...

I tried to import the regitry key but PHMRegitryEditor returns me an error.
Then I put the 4 files in \Windows folder too

but nothing works...

Any idea to re-enable DUN on WM5 Hermes?


P.S.
neither "BT_DUN.cab", nor "WM6_BT_DUN.cab" (I found them on XDA Forum) works on WM5 Hermes

Plase do follow my earlier articles - in the Registry Editor Bible ( http://www.pocketpcmag.com/blogs/men...tryEditors.asp ), I've explained why this is happening: PHM isn't compatible with RegEd 5 scripts.

Solution: use Resco.

I tryed also with SOTI Pocket Controller Pro... Nothing to do!

It shoud be possible create a CAB installer for all devices, without using regitry editors, for this re-enabling operation? I'm not able.

Do you suggest Resco Regitry Editor for this case?

Anyway, don't forget to use the string
+cgdcont=1,"IP","APN_own_operator"
in modem advanced settings (on PC).

Not that important, as is also pointed out in my related tutorials. If you use *99#, the phone will use the default data account. No need for supplying anything extra.

It' s wrong... If I use only *99#, I'm not able to connect the phone to web...
But if I use the string, I can...

It's strange, but it happens.
