Handling large numbers of SMS and other problems with Nokia 3500c

[Krylov Ivan]

Hi!

I'm a user of Nokia 3500c. I usually write and receive lots of messages 
and tend not to delete them until phone's memory is full.

Some days ago I thought that slower phone startup can be caused by
unusually big number of messages being in the phone memory, so I wanted
to download them to my computer and delete them from phone.

First of all, 3500 classic doesn't allow SMS reading or writing through
AT-commands, so I set up priviledges for libusb:

> # /etc/udev/rules.d/45-nokiadku2.rules

> ACTION!="add", GOTO="nokiadku2_rules_end"
> SUBSYSTEM=="usb", GOTO="nokiadku2_rules"
> # This one is for the old kernels
> SUBSYSTEM=="usb_device", GOTO="nokiadku2_rules"
> GOTO="nokiadku2_rules_end"
>
> LABEL="nokiadku2_rules"
> ATTRS{manufacturer}=="Nokia", MODE="0660", GROUP="plugdev"
>
> LABEL="nokiadku2_rules_end"

and enabled the dku2libusb method (I'm using a USB-miniUSB cable to
connect my phone to the computer; phone cannot be charged via miniUSB):

> # ~/.config/gnokii/config

> [global]
> model = series40
> port = 1
> connection = dku2libusb
>
> [logging]
> debug = on
> xdebug = on

After running `gnokii --showsmsfolderstatus` program hanged for some 
time and returned an error: "command timed out". Enabling debug mode 
showed that command is not actually timing out, but the phone cannot 
list all messages in time before timeout reaches (file: gnokii.log.gz)

Tweaking NK6510_GETFILELIST_TIMEOUT on line 209 from 500 to 9500 in 
include/phones/nk6510.h of the latest git snapshot made me able to list 
the messages, but the program noted that values more than 1024 are very 
strange for it and asked to report a bug (file: gnokii.9500.log.gz).

What modifications should be done to make Gnokii handle large numbers of 
messages properly? I tried to move timeout setting deeper in the message 
handling loop (in the common/gsm-statemachine.c:__sm_block_timeout 
function), but that didn't help, so I had to tweak timeout instead. I 
guess that my C knowledge wouldn't help me with the "1024" warning either.

By the way, I have not been able to get the messages from my phone. The 
--get command usually returns "The given memory location is invalid" 
(log: gnokii.getsms.log.gz) despite messages actuallly being there; I 
was able to "get" the message once, but is was empty and sent and 
delivered in 2000 (sorry, did not save it and couldn't reproduce it 
later). I also received "an error in the device handling code" and 
"phone returned short message" a few times, and did not save these logs 
too, unfortunately.

Best regards,
Ivan.
