[PATCH] sim: fix crash in case of invalid sim password type
by Christophe Ronco
Hi,
I have an old Swedish SIM card here that I tried to put in my MC7304 modem.
My ofono version is 1.20 (with some additional patches).
It sometimes return an invalid SIM password type.
After that, ofono crashes. Here is an extract of debug traces when this happens.
Ofono is just starting, modem was here before ofono starts.

ofono with sim5320 module
by David Ashley
Hello, I'm at my wits' end trying to get ofono working with the
sim5320 module. I'm using the plugins/sim900.c module as a starting
point. I think the issue has something to do with the difference
between the MUX functionality between the 900 and the 5320. The sim900
supports the elaborate parameters sent on the
AT+CMUX=0,x,x,x,x, etc.
but the SIM5320 only supports
AT+CMUX=0
There's that... but also the way the sim900 plugin creates a
SETUP_DLC, initiates muxing, then deletes the setup DLC and creates 4
new DLC's... it didn't work for the sim5320 until I remapped the DLC's
somewhat like this:
#define NUM_DLC 4
#define VOICE_DLC 2
#define NETREG_DLC 1
//#define SMS_DLC 2
#define GPRS_DLC 3
#define SETUP_DLC 0
static char *dlc_prefixes[NUM_DLC] = {
[VOICE_DLC]="Voice: ",
[NETREG_DLC]="Net: ",
// [SMS_DLC]= "SMS: ",
[GPRS_DLC]= "GPRS: " ,
[SETUP_DLC]= "Setup: ",
};
Note I have to eliminate the SMS_DLC usage later in sim5320_post_sim:
// ofono_sms_create(modem, OFONO_VENDOR_SIMCOM, "atmodem",
// data->dlcs[SMS_DLC]);
OK everything is *ALMOST* working. ofonod interacts fine with
connmand, connmand tells ofonod to activate the sim5320, which
actually establishes a ppp connection and sets up a ppp device:
ppp0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-0
inet addr:30.97.132.47 P-t-P:30.97.132.47 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:0 (0.0 B) TX bytes:124 (124.0 B)
Here's the rub: No matter what I do, I never get any RX packets from
that ppp device, and even when it appears to TX packets (I'm trying to
ping out) the machine on the internet isn't actually receiving them.
I'm running on a beaglebone with a custom board with a sim5320 module on it.
I have no idea what to try... Any advice would be appreciated...
Thanks very much!!!!

[PATCH] nokia-gpio: do not create links to gpios in /dev/cmt
by Clayton Craft
The nokia-gpio plugin should not try to create symlinks to relevant gpio
pins under /dev/cmt, since the location it is looking is no longer
correct on newer kernels and it might change again in the future. This
patch removes code from nokia-gpio that tries to create a symlink.
Users will now need to symlink the modem gpios to /dev/cmt themselves.
On the 4.13 kernel, this can be done by, for example, adding a udev rule
to:
# ln -sf /sys/bus/hsi/devices/n900-modem /dev/cmt

[PATCH 0/2] huawei E3372: add LTE support
by Christophe Ronco
Hi,
Here is a first version of patches to support LTE with E3372 USB keys.
Huawei has two AT command sets to deal with band and mode (technologies).
Standard AT commands set (AT^SYSCFG, AT^SYSINFO, ^MODE, ...) handle 2G and 3G technologies only.
Extended AT commands set (AT^SYSCFGEX, AT^SYSINFOEX, ^HSCQ, ...) handle 2G, 3G and 4G technologies.
Extended commands are described in this document (downloadable on the web):
HUAWEI ME906s LTE Module AT Command Interface Specification-(V100R001_01, 0English).pdf
Huawei driver in Ofono uses standard AT command set. When it says to use any band in any technology to connect, this disable 4G.
Fix consists in using the other command set to do the same thing when it is supported.
^HCSQ notification is also able to report LTE attachment while ^MODE reports UMTS attachment when modem is attached in 4G.
Tests have been done only with E3372, with 3G and 4G SIM cards. I don't have any 3G only huawei modem.
Technology report in network-registration.c works only because notification come in this order:
1) PCUI: < \r\n^MODE: 5,4\r\n
2) PCUI: < \r\n^HCSQ:"LTE",38,34,101,28\r\n
3) PCUI: < \r\n^SRVST: 2\r\n\r\n+CREG: 1,"C0FA","00107202"\r\n
I have never seen notifications in other order but I don't have a Huawei document saying it won't happen.
I will be happy to have your comments on these patches.
Best Regards,
Christophe Ronco

I've done 2,000 miles on my Rival 22 hydraulics through the worst that English winter has to throw, they're pretty good. They squeal now and again, usually while braking at slow speeds after 20 minutes of riding through dirt and mud and not braking at all. During rain they also make that metallic chafing sound, but that isn't really a big deal. I've just replaced the front pads (I used RED pads from superstarcomponents).
I have no experience of Shimano road hydraulics but the XT brakes on my MTB have always been fine.

Support for samsung-ipc
by Tomáš Šafařík
Hello,
I would like to ask about support for Samsung devices that use IPC like i9100 (galaxys2). I would like to get it work for postmarketOS project - http:/wiki.postmarketos.org/
I found this old post https://lists.ofono.org/pipermail/ofono/2012-September/013766.html that send patchset for support via libsamsung-ipc. But I do not see any samsung driver in current repository.
Does please anyone have any info about this topic ( is it supported, was the patchset included, etc. )?
Thanks,
