Sierra MC7455 module not identified as modem by Ofono

by Eswaran Vinothkumar (BEG/PJ-IOT-EL)

Hello, For my project I am planning to use Sierra MC7455 module. I want to use the module along with ConnMan & oFono. The versions used are: Connman: 1.34 Ofono: 1.20 Linux Kernel : 4.9.39 After plugging in the module I could see that the device getting attached and the interface cdc-wdm0 is available. The log messages are as shown: Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: New USB device found, idVendor=1199, idProduct=9071 Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: New USB device fqmi_wwan 1-1.1:1.8 wwan0: register 'qmi_wwan' at usb-ci_hdrc.1-1.1, WWAN/QMI device, fa:37:7b:9e:49:2a ound, idVendor=1199, idProduct=9071 Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: Product: Sierra Wireless MC7455 Qualcomm® Snapdragon(tm) X7 LTE-A Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: Product: Sierra Wireless MC7455 Qualcomm® Snapdragon(tm) X7 LTE-A Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: Manufacturer: Sierra Wireless, Incorporated Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: Manufacturer: Sierra Wireless, Incorporated Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: SerialNumber: LQ71660082041020 Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: SerialNumber: LQ71660082041020 Sep 07 12:34:00 cl-som-imx7 kernel: qcserial 1-1.1:1.0: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel[215]: qcserial 1-1.1:1.0: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB0 Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB0 Sep 07 12:34:00 cl-som-imx7 kernel: qcserial 1-1.1:1.2: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel[215]: qcserial 1-1.1:1.2: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB1 Sep 07 12:34:00 cl-som-imx7 kernel: qcserial 1-1.1:1.3: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB1 Sep 07 12:34:00 cl-som-imx7 kernel[215]: qcserial 1-1.1:1.3: Qualcomm USB modem converter detected Sep 07 12:34:00 cl-som-imx7 kernel: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB2 Sep 07 12:34:00 cl-som-imx7 kernel[215]: usb 1-1.1: Qualcomm USB modem converter now attached to ttyUSB2 Sep 07 12:34:00 cl-som-imx7 connmand[213]: wwan0 {create} index 6 type 1 <ETHER> Sep 07 12:34:00 cl-som-imx7 connmand[213]: wwan0 {update} flags 4098 <DOWN> Sep 07 12:34:00 cl-som-imx7 connmand[213]: wwan0 {newlink} index 6 address FA:37:7B:9E:49:2A mtu 1500 Sep 07 12:34:00 cl-som-imx7 connmand[213]: wwan0 {newlink} index 6 operstate 2 <DOWN> Sep 07 12:34:00 cl-som-imx7 connmand[213]: Adding interface wwan0 [ cellular ] Sep 07 12:34:00 cl-som-imx7 kernel: qmi_wwan 1-1.1:1.8: cdc-wdm0: USB WDM device Sep 07 12:34:00 cl-som-imx7 kernel: qmi_wwan 1-1.1:1.8 wwan0: register 'qmi_wwan' at usb-ci_hdrc.1-1.1, WWAN/QMI device, fa:37:7b:9e:49:2a Sep 07 12:34:00 cl-som-imx7 kernel[215]: qmi_wwan 1-1.1:1.8: cdc-wdm0: USB WDM device Sep 07 12:34:00 cl-som-imx7 kernel[215]: qmi_wwan 1-1.1:1.8 wwan0: register 'qmi_wwan' at usb-ci_hdrc.1-1.1, WWAN/QMI device, fa:37:7b:9e:49:2a I tried to run the test scripts under ofono, but it doesn't able to identify any modem devices. The log messages are as shown: root@cl-som-imx7:/usr/lib/ofono/test# ./list-modems root@cl-som-imx7:/usr/lib/ofono/test# root@cl-som-imx7:/usr/lib/ofono/test# ./enable-modem Traceback (most recent call last): File "./enable-modem", line 14, in <module> path = modems[0][0] IndexError: list index out of range root@cl-som-imx7:/usr/lib/ofono/test# It would be great if you get help me in identifying the issue. Mit freundlichen Grüßen / Best regards Vinothkumar Eswaran BEG-PT/PJ-IOT1

[PATCH] gdhcp: Fixed IPv4 link-local IP conflict error.

by Niraj Kumar Goit

In IPv4 link-local IP configuration, during the ARP probe period if ARP packet is received with the source mac-address that matches client mac-address it will incorrectly cause a IP conflict error. So, in the received ARP packet if source mac-address matches the client mac-address return '0'. --- gdhcp/client.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/gdhcp/client.c b/gdhcp/client.c index 3e67fcd..6735778 100644 --- a/gdhcp/client.c +++ b/gdhcp/client.c @@ -1423,6 +1423,9 @@ static int ipv4ll_recv_arp_packet(GDHCPClient *dhcp_client) arp.arp_op != htons(ARPOP_REQUEST)) return -EINVAL; + if (memcmp(arp.arp_sha, dhcp_client->mac_address, ETH_ALEN) == 0) + return 0; + ip_requested = htonl(dhcp_client->requested_ip); source_conflict = !memcmp(arp.arp_spa, &ip_requested, sizeof(ip_requested)); -- 1.9.1

Connman coredump

by Cliff McDiarmid

Hi Must apologize for other unconnected emails that have dropped in forum. Still trying to figure how that occured. I've been using Connman for about three years and have had nothing but success. But I've just installed into a Gnome3 64bit systemd system. I'm now experiencing dumps every five minutes or so, after restarting the connection, into /var/lib/connman. These consist of sizable files labelled 'stats-918J6Y', as an example, of up to a gig in size. There is nothing obvious from the journal log, but maybe the following? Sep 15 23:21:48 cliffhangers org.gnome.Shell.desktop[3244]: Window manager warning: Invalid WM_TRANSIENT_FOR window 0xe00007 specified for 0xe00005 (Connman Sy).

Can someone advise here? thanks Cliff

Using connman programmatically from C++ source code

by Giovanni Parodi

Good morning, I'm a new user of connman SW and I would like to integrate it in a C source code. I would like to do something like linking wpa_cli in order to programmatically use this SW. However I found nothing related to this topic on the project documentation (I found lot of examples about the CLI, but no way to use standard C/C++ API). My SW needs to: - configure WiFi connection - scan WiFi - Connect to WiFi AP - manage ppp connections Any help will be appreciated Best regards Giovanni

💰I want you inside my head

by Cliff McDiarmid

Basically, I want you to understand my mindset. Sure, this is a bit of a “how-to” guide, but more importantly, I want you to really get an understanding of how I think and why I’ve built my business the way I have. If you can start seeing things from my perspective, the mysterious world of affiliate marketing will start to open up to you.
