Johan Hedberg on the developer list explained the inner workings of Nokia 770 Bluetooth module, since a lot of developers voiced concerns that having page scans and inquiry scans disabled for security reasons would make 770 a tough player in home PAN networks.
By default, the 770 will have both page scan and inquiry scan disabled (i.e. be non-connectable and non-discoverable). Enabling those scan modes is just a matter of issuing a simple HCI command. For example using the bluez-utils command line tools you can enable both scans the command “hciconfig hci0 piscan”. However, there will be no way to enable the scan modes from the default 770 UI.
I hope Nokia will enable the Bluetooth Human Interface Device Protocol (HIDP) kernel module in Bluez in N770 linux kernel when released. HID module support HID devices e.g. bluetooth keyboard and mouse.
N770 uses Bluez.

BTW, Nokia has bluetooth keyboard already

Thanks. Noli
P.S. command line interface (cli) is the asset of linux.
Comment by NS 07.01.05 @ 6:49 amNo, it is available in third (3rd) quarter of 2005.
It seems that hidp support is compiled now with N770 kernel. Hence, bluetooth keyboard is working partially.

Comment by NS 07.04.05 @ 6:20 amHmm… I have the 770 brandnew and the xterm on it. But what is the root-pw on that thing to switch the hciconfig-stuff on? I’d like to use my laptop as gateway via bluetooth since I don’t have WiFi everywhere where my laptop is…
Comment by Rince 10.22.05 @ 7:15 amDitto Rince’s comment - I’d very much like to be able to get internet on my 770 over Bluetooth.
When I select my PC as a ‘phone’, a dialog pops up on the 770 saying “Selected phone does not support dial-up networking. It can be used only for transferring files.”
Is there perhaps a way to emulate a bluetooth modem using the PC? I suppose this might be the simplest solution? (least fiddling with the 770/command-line shennanigans anyway..)
As an aside, I couldn’t get file-sharing to work either - my PC appeared as an entry in the 770’s file manager but the tablet kept saying it couldn’t connet… :\
Is there a forum for this kind of stuff yet BTW? I haven’t been able to find much out there…
Would appreciate if someone could point me in the right direction

Hi
I have a new 770 that I am trying out for various applications at work and I CANNOT pair it with my Sony Ericsson P910 (WiFi works fine). Anyone had a similar problem, or better, a solution? I enter the passkey on the P910 and the 770 fails to pair …
I CANNOT pair it with my audiovox smt5600 windows smartphone. It fails when trying to pair the phone with the 770.

I am having the same difficulty. I’ve just got the 770, so perhaps there is some trick to it. Airbillion, did you ever get this combination to work?
Comment by sfriedberg 01.07.06 @ 6:17 amLove the 770. Wifi works. Browser goes to sites that only laptop IE or firefox will go to.
Bluetooth hookup for web access is worthless. Won’t connect to treo 650 which pdanet bluetooth hooks to laptop fine. Went to Sprint Verision T-Mobile and Cingular stores and tried to make an internet connection with every phone that their tech’s had. None worked. Nokia tech doesn’t have a clue of what’s happening,
BT problem in more detail:
I have got a problem when sharing an internet connection through BlueTooth.
Using Win2000 with an xDSL modem connected through an ethernet card (this is the internet connection)
and a USB BT Dongle using Widcomm software ver.1.2.2.9 to share it with the 770.
The problem is the error msg. appearing on the 770 after succesful pairing:
“Selected Phone does not support dial-up networking. It can be used only for transferring files.”
It seems that the machine does not care about succesful sharing of the (xDSL) Network Access.
Yes, when checking the BT services under “My Device” on the PC, the “Network Access” icon was active
(The xDSL connection is shared for the BT), but the “Dial-Up Networking” icon was not active.
Logical: maybe because of the (xDSL~NetworkAccess) connection. Well, tried to rename
the “Network Access” icon to “Dial-up networking”: does not help. Does anybody have an idea
how to make the 770 think that the xDSL connection shared is of “dial-up” type?
Tanks a lot, m.
Comment by marian 03.05.06 @ 5:49 amregarding sharing the internet connection of a PC..
would it help to update the icd package as proposed on this site,
by
sudo gainroot
su -
/etc/rc1.d/K15osso-ic stop
mv /usr/sbin/icd /usr/sbin/icd.old
cp /media/mmc1/icd /usr/sbin/icd
/etc/rc3.d/S40osso-ic start
sdpd
or this is this icd problem only related with mobiles?
ok, you may ask why not sharing the connection under linux. well, i have tried it with suse 10.0, using the same dongle, and the 770 is easy to pair with suse, but did not find any services of the PC.
strange. could it really be that the “service discovery protocol daemon doesn’t start automatically when the tablet starts”?
how do we start it?
help pls!!!
