We are trying to implement a demo of a mobile industrial sensor via
android. One of the goals of the demonstration is to send data to a
web site. The cell modem is working for SMS messages via the
reference RIL just fine. We would like to use GPRS to allow somewhat
more data. We currently have the gsm0710muxd working, with one
channel connected to the RIL, the other connected via chat/pppd such
that ping works from the Linux console. What we can't seem to figure
out is how to get Android to use the default route that is set up via
pppd. Can anybody give me some pointers on what needs to be done to
get Android to use the connection? Thanks much in advance.

Which is the full command you are using for setting the route?
Can you explain a little bit more your process?

Hi ms12,
We created a setup where a 3G mobile broadband dongle works as telephony backend for Android Eclaire (without voice calls of course). It sounds similar to what you guys are doing.
I believe that implementing an ip-up script in /system/etc/ppp will make things work:
/system/etc/ppp/ip-up should contain something like this:
/system/bin/setprop "net.interfaces.defaultroute" "gprs"
/system/bin/setprop "net.gprs.dns1" "$DNS1"
/system/bin/setprop "net.gprs.dns2" "$DNS2"
/system/bin/setprop "net.gprs.local-ip" "$IPLOCAL"
/system/bin/setprop "net.gprs.remote-ip" "$IPREMOTE"
/system/bin/setprop "net.gprs.gw" "$IPREMOTE"
This script will run every time PPP sets up a connection and provide Android with the correct gateway, dns, etc. To check that it actually ran, I added the following:
/system/bin/log -t pppd "IP-UP TRACE for gprs"
/system/bin/log -t pppd "DNS1 $DNS1"
/system/bin/log -t pppd "DNS2 $DNS2"
/system/bin/log -t pppd "local-ip $IPLOCAL"
/system/bin/log -t pppd "remote-ip $IPREMOTE"
/system/bin/log -t pppd "gw $IPREMOTE"
..which will throw useful information into logcat output.
You can also make a /system/etc/ip-down script to change things back the way they were (if you have multiple ways of connecting to the internet).
But how do you initiate the PPP connection? Via Android RIL or just via init? I am unsure of whether Android will understand that it has a GPRS packet data connection without proper handling in the RIL (I don't know if setting the above properties is sufficient)...
You should be aware that in later Android releases you need some security hacks to allow the RIL to spawn the PPP process (which must run as root), and you need some tweaky plumbing to ensure proper interaction between RIL & PPP during handling of RIL_REQUEST_SETUP_DATA_CALL...
Let me know how you get along with this.

Thanks much for the pointers, we are certainly missing some of the
setprop's. I will try those. However, we are using Donut (1.6) and I
wonder if they will work there.
More detail:
I've not been able to see my way clear to setting up the data call via
the RIL. I think I could spawn ppp (via system(pppd ...) ??) and
connect it to the second CMUX channel when REQUEST_SETUP_DATA_CALL
happened, but I would still need to tell Android to use that channel,
not the original command connection, and I can't see how to do that.
So what I did was run pppd (with scripts and chat to dial the "ISP"
and using the alternate mux channel on /dev/pts/0) outside of the RIL
from the console. This works, the connection is established, and I
do a setprop net.dns1 manually. (I believe the scripts are doing a
"defaultroute" when pppd starts, the equivalent of route add default
gw xx.xx.xx.xx dev ppp0 I do not need to run route explicitly). At
this point I can ping www.google.com, but any attempt to start the web
browser from Android touchscreen just hangs or gives an error.
Thanks again for the help.

When the browser hangs/errors, can you take a bugreport or capture the logs? That may shed light on the issue.

Here is a copy of the console log. I did the setprop's suggested
above, checked the ping, cleared the logs, the pressed the browser
icon. Then did a logcat which resulted in this. (Thanks!) Mike

In case you use route command, check this. It may help you

Hello Mstich12,
I do think those settings should work with Donut (we were inspired by a Donut setup), but as I said, maybe they're insufficient. I never figured out from your reply if you tested these properties and if it brought you any further?
What we did to setup PPP was to create a service "pppd_gprs" inside init.rc. This service runs a script that:
1. Sets a custom property to let us know that PPP is starting
2. Runs pppd as:
/system/bin/pppd $* connect 'chat -v -s -f /system/etc/chatscript' nodetach debug defaultroute ipcp-accept-remote ipcp-accept-local usepeerdns
3. Sets another customer property in which we set the exit code of ppp
Then this service is started from inside the RIL during handling of REQUEST_SETUP_DATA_CALL, by setting the property "ctl.start" to "pppd_gprs". This is the point that needs a security hack (at least in Éclair release), or the service does not start at all. Let me know if you need this hack, and I can send a patch...
Once the service is started and PPP is running (this is in fact not trivial to figure out), we read the "net.gprs.local-ip" set by the ip-up script and passes this back in the reply to REQUEST_SETUP_DATA_CALL.
Since PPP connectivity is handled by a script in its own service, you have the freedom to choose exactly which tty it should connect to (in the setup above it takes it from the service parameter stated in init.rc). That being said, you may have to tweak a little to make sure that the needed AT commands to set up everything is sent on the right channel. For example we setup the PDP context using one channel (the AT+CGDCONT=1,"ip","internet" stuff) and PPP connection via another one (the ATDT*99***1# and PPP stuff). Requirements may be different for your modem...
Try running a "logcat -b radio" - this will give some useful log information from Android's radio & connectivity layer...

I do think those settings should work with Donut (we were inspired by a Donut setup), but as I said, maybe they're insufficient. I never figured out from your reply if you tested these properties and if it brought you any further?
What we did to setup PPP was to create a service "pppd_gprs" inside init.rc. This service runs a script that:
1. Sets a custom property to let us know that PPP is starting
2. Runs pppd as:
/system/bin/pppd $* connect 'chat -v -s -f /system/etc/chatscript' nodetach debug defaultroute ipcp-accept-remote ipcp-accept-local usepeerdns
3. Sets another customer property in which we set the exit code of ppp

Hi!
I think you're totally right - this is the last part you need to figure out.
We have the following code to start the service (and yes - it starts the service in init.rc):
err = property_set("ctl.start", "pppd_gprs");
LOGD("starting service pppd_gprs...");
if (err < 0) {
LOGD("### error in starting service pppd_gprs: err %d", err);
goto error;
};
BUT for this to work, you have to hack system/core (see attached patch), or RIL won't have permissions to start the service. Whether this is the right way to go, I don't know; there may be better and more secure ways of getting the job done, and it seems Google wants to tighten security in this area. And maybe you don't even need the hack on Donut...
When you need to stop the service - just set the property "ctl.stop" - you get the idea :-)
Regarding ip-up & ip-down: Yes - these are started by pppd and supplies the various variables such as $IPLOCAL.
I cannot share all the code, since I am unsure of what our company policy says about it. That being said I think you're almost there. Just make sure that you send a properly formatted reply to the REQUEST_SETUP_DATA_CALL with the obtained IP inside (hint: use property_get("net.gprs.local-ip", address_ip ,"") to retrieve the ip set by ip-up).
If we need to go deeper here, please post output of 'logcat -b radio' :-)

Hello Henrik,
The settings did not make it work. I start the ppp session from the console manually, and it connects properly as evidenced by ping working. My problem I think is related to not understanding how to start the ppp session inside of REQUEST_SETUP_DATA_CALL and then get Android Telephony to use it for data.
The property ctl.start is new to me, how is that set in RIL? Does that trigger the service from init.rc somehow?
I'm also not sure how ip-up knows what the local and remote IP's are. Does the call to pppd call ip-up automatically with $IPLOCAL?
If it is not too much to ask, could you send some example code? Things like your REQUEST_SETUP_DATA_CALL and the associated close data call, any germane ppp scripts (ip-up, ip-dn ?), the service pppd_gprs section of init.rc, and the permission hack patch.
I think I have all the bits working, I'm just not sure how to hook them all together. Thanks much for your help
Mike
