[Theory] Allow dr800sg using third party SIM card

[jackotman]

Hi All
here just a theory.
if i add new file in
#note that APN need to change to your ISP APN
/etc/ppp/chat-other-3g

ABORT BUSY
ABORT 'NO CARRIER'
ABORT ERROR
TIMEOUT 30
'' 'ATE1'
ok 'ATZ'
OK 'AT&F'
OK 'AT_OPSYS=1'
OK 'AT+CGDCONT=1,"IP","APN"'
SAY "Calling...\n"
TIMEOUT 120
OK "ATD*99***1#"
CONNECT \c

notes:
'' 'ATE1' Echo off
ok 'ATZ' soft reset
OK 'AT&F' load default profile
OK 'AT_OPSYS=1' only using 3G
OK 'AT+CGDCONT=1,"IP","APN"' Setup APN
SAY "Calling...\n"
TIMEOUT 120
OK "ATD*99***1#" Dual number
CONNECT \c

And modify
/etc/ppp/peers/provider

# PPP config for others
connect "/usr/sbin/chat -v -f /etc/ppp/chat-other-3g"
debug
/dev/ttyUSB1
115200
defaultroute
noipdefault
crtscts
noauth
user guest
password guest
usepeerdns
novj
nodeflate
nobsdcomp

I thought the dr800sg could using the SIM card to do the dialup.

Please let me know it is wrong.

What about the little matter of switching the radio from cdma to gsm?

You will need the firmware provided on the windows installation to allow the card to run. In my installation, the files on the windows side were under \QUALCOMM\QDLService\Packages\1\ (Your path may be different. There were 10 different sets of firmware included on my windows partition, it took a bit of trial and error to determine which firmware worked and which didn’t. What appears to be the case is the amss.mbn for GSM is roughly 9MB and the amss.mbn for CDMA is roughly 5MB. For Verizon, you want the CDMA file and it’s associated apps.mbn.

The two files amss.mbn and apps.mbn will need to be copied into /lib/firmware/gobi/ If this folder does not exist, you will need to create it.

************************************************** *******************************


I found out that /Qualcomm wireless need to load the right firmware to config itself access GSM or CDMA network.

the firmware will load on when the device power on and I also sure when your device has been restart, the firmware need to be reload.

however I not sure that firmware will be loaded or not when you send "ATZ" command to soft reset the device.

in IREX /opt/Qualcomm/Images2k/iRex# /Qualcomm folder there are two subfolder:
1 -> CDMA firmware
UMTS -> GSM firmware

in /opt/Qualcomm/QDLService2k folder
there are two file:
-rw-r--r-- 1 root root 117 1969-12-31 19:00 Options2kiRex.txt
-rwxr-xr-x 1 root root 139K 1969-12-31 19:00 QDLService2kiRex

As my guess, Options2kiRex.txt is the cofig file and QDLService2kiRex is the firmware download exe file.

Well, this blog seems abandoned... Anyway, my findings about the Qualcomm Gobi drivers, as I had some free time to dig into the issue:

- if I extract the HP WWAN installer, I find two separate MSI installers made by Qualcomm. One installs the so called "Gobi images" which seem to be settings for the various WWAN service providers (like Verzion, etc. and european UMTS providers). The other one installs the drivers and the QDLService ("Qualcomm Gobi Download Service"), which seems to be a loader of some sort, which has the task to load the correct "Gobi image", depending on the current provider. This latter installer is the one, which fails with a generic error.
************************************************** ******************************************

here is the info in /opt/Qualcomm/QDLService2k# cat Options2kiRex.txt
/opt/Qualcomm/Images2k/iRex/1/amss.mbn
/opt/Qualcomm/Images2k/iRex/1/apps.mbn
/opt/Qualcomm/Images2k/iRex/1/uqcn.mbn

What i guess that if i change Options2kiRex.txt to
/opt/Qualcomm/Images2k/iRex/UMTS/amss.mbn
/opt/Qualcomm/Images2k/iRex/UMTS/apps.mbn
/opt/Qualcomm/Images2k/iRex/1/uqcn.mbn

the USIM fireware will be loaded.

Also, I think if you can put "chat-other-3g" file to the SD card and ask "/etc/ppp/peers/provider" load that file from SD card mount point. You can always change the APN when you use different SIM card.

Just a caution, but what iRex has said about this is that the reason the 3G isn't included outside of the US is that they don't have agreements with any carriers. Theoretically it may be possible to change the code ourselves to get it to work, but they warn that carriers will sometimes blacklist an unknown device that they see connecting to them, even with a SIM card. In other words, the SIM may work on their network, but sometimes they won't consider the device authorized.

With that said... good luck! This would be cool if you could get it working.

I am not a good linux programmer.
I just wanta know does any genius programmer here can help me write a simple shcript to test my theory?

Does this even happen, if you've got a flatrate for unlimited (web)traffic? I guess, that's the only kind of contract which would make sense. And my guess would have been, the providers of flatrates wouldn't care about such little traffic...

This seems a non-sense to me. After all, there are many cell phones, unknown to carriers.
Also, i believe that carrier only knows IMEI code of the device, not the manufacturer/model number.

I believe on the newer kernels the gobi is supported through the qcserial driver. Now I only had a gobi on my desk for 3 days for a Windows box so I cannot comment on it, best bet is to look at what the NetworkManager guys are doing for gnome/kde.

I don't know how the carrier would know, or if they would really care. Just passing on the warning that iRex gave in their forums about it. I think what iRex is really saying is that if something does happen and a carrier blocks you, iRex isn't responsible. I don't know how likely it is that it would happen.

Well, Irex doesn't support third-party SIMs officially, so i can't see how irex can be responsible if one will be unable to use certain third-party SIM in their DR800SG.
Or is it something like "don't put cats in your microwave"?

[vakya]

Pardon for my english.

I am in Spain and I have to try several SIMs. Even companies that offer no phone in their contracts (are you sure you do not put paste).

Jackotman, if you want to experiment with me I am ready. I just saw this message and not if you have already tested your theory.

I think all the dogs in the audience would enjoy microwaving those cats.

Are you talking about me?

Jackotman, I tried what you say but these files in version 2.0 beta no longer exist.

Hi, I am just trying to edit the DR800 SG firmware according to your explanation. How can I find the path on my Mac? Thanks for you help!
