Description Marshall Jose (reporter) 2007-03-17 18:48:06 UTC 
The N800 issues at least one AT command at connect-time which many Nextel
(iDen)
cellphones don't recognize. The N800 then improperly concludes the cellphone is
unready for connection. The result is that the cellphone briefly announces a
bluetooth connection, then quickly announces BT disconnection.

The problem shows itself on my cellphone (i605) which provides a problem-free
connection on Windows and other Linux computers, neither of which send any of
the advanced (AT+) queries to the cellphone. I believe the fix would involve
either auto-recognition of the phone or else allowing the user to request a
simpler connection method (e.g., one which doesn't require an answer from
AT+GCAP). Perhaps the fix could be made at the same time bug #1095 is
addressed. 

N.B. See the "sdptool browse" output at the end of this posting.

Comment 1 Marshall Jose (reporter) 2007-04-04 13:23:44 UTC 
Bug also exists in 3.2007.10-7, apparently within gwhwdetect.
Comment 2 Andre Klapper maemo.org 2008-06-03 21:06:10 UTC

The phone is actually failing a test, where ICd checks that the HW of the phone
supports the cellular type of the selected IAP (e.g. that GSM phone is used
with GSM IAP and CDMA phone is used with CDMA IAP).

I have a strong feeling that we do _not_ want to drop this check. Furthermore,
I don't think we have any requirement to support iDEN networks - at least we do
not have any UI options to select any other networks than GSM/UMTS or CDMA.

Should I resolve this one as WONTFIX or remove the check? If I remove the
check, it probably does not make much sense to run any "detection AT commands"
in ICd (outside gwhwdetect). Probably I could also make a gconf key, which set
the ICd would skip the detection.

------- Comment #9 2007-06-07 16:35:52 -------

There is requirements to support only GSM and CDMA, not iDEN, thus this bug is
WONTFIX.

*If* I have time, I'll make an optional/hidden IAP specific GConf setting to
disable "cellular network type detection". This hack could then be used to
connect also iDEN phones.
Comment 3 Andre Klapper maemo.org 2009-01-20 17:46:22 UTC 
This is still valid for latest Diablo (5.2008.43-7) I assume?
