Denis,
I noticed from the logs that 'net' should have been probed by
huawei_cdc_ncm module instead of plain cdc_ncm. I managed getting sysfs
lines after "net finished" line in ofonod log after changing cdc_ncm to
huawei_cdc_ncm (below):
..plugins/udev.c:udev_event() subsystem net finished
..plugins/udevng.c:check_usb_device() huawei_cdc_ncm [12d1:1506]
..plugins/udevng.c:add_device()
/sys/devices/platform/ocp/47400000.usb/47401c00.usb/musb-hdrc.1.auto/usb2/2-1
..plugins/udevng.c:add_device()
/sys/devices/platform/ocp/47400000.usb/47401c00.usb/musb-hdrc.1.auto/usb2/2-1/2-1:1.1/net/wwan0
..plugins/udevng.c:add_device() wwan0 (huawei) 255/2/22 ==> (null) (null)
I also got net record from setup_huawei() printout:
..plugins/udevng.c:setup_huawei() mdm=/dev/ttyUSB0 pcui=/dev/ttyUSB2
diag=/dev/ttyUSB1 qmi=(null) net=wwan0
Now this process proceeded further providing printout from
provision_get_settings():
..plugins/provision.c:provision_get_settings() Provisioning for MCC 244,
MNC 05, SPN 'elisa'
..plugins/provision.c:provision_get_settings() Found 1 APs
..plugins/provision.c:provision_get_settings() Name: '(null)'
..plugins/provision.c:provision_get_settings() APN: 'internet'
..plugins/provision.c:provision_get_settings() Type:
OFONO_GPRS_CONTEXT_TYPE_INTERNET
..plugins/provision.c:provision_get_settings() Username: '(null)'
..plugins/provision.c:provision_get_settings() Password: '(null)'
After that came some errors:
..src/sim.c:ofono_sim_remove_spn_watch() 0x11cf60
ofonod: PCUI: > AT+CPBS=?\r
ofonod: PCUI: < \r\n+CME ERROR: 14\r\n
ofonod: PCUI: > AT+CPBS=?\r
ofonod: PCUI: < \r\n+CME ERROR: 14\r\n
ofonod: PCUI: > AT+CPBS=?\r
ofonod: PCUI: < \r\n+CPBS: ("SM","EN","ON")\r\n\r\nOK\r\n
I did not see any progress on connman side.
Modifications in plugins/udevng.c
vendor_list[]:
{ "huawei", "huawei_cdc_ncm", "12d1" },
setup_huawei():
g_strcmp0(info->interface, "255/2/22") == 0 ||
g_strcmp0(info->interface, "255/1/56") == 0) {
net = info->devnode;
Where should I look next?
I could provide full log, but I am not sure if attachments/messages with
attachments pass through.
Thanks,
Matti
