Hi,
My 3G modem (Huawei E5) fails to setup network connection after long time
'associating'.
By trace the debug log, it is found that the PPP is not setup. The callback function
at_cgdcont_cb() is not ever called, which is set to callback function when sending AT
command 'AT+CGDCONT=cid' in function at_gprs_activate_primary();
The callback function at_cgdata_cb() is not called, thus the PPP is not setup. Do you have
seen similiar same issue?
I paste the debug log with AT commands.
Thanks,
Best regards,
Y.A.

It sounds like the udev detection is telling oFono to use the wrong tty
for the modem device. It might be using one of the binary ports which
is not replying to AT commands. You will need to investigate this and
update the udev rule appropriately.

Thanks for your prompt reply.
I noticed that only ttyUSB0 and ttyUSB1 are exposed, but on Windows, there are four ports
(0-3) instead.
The Pcui are attached to ttyUSB1 - which is Mass storage port shown on Windows. On
Windows, the Pcui are port 2.
Though I force to write in ofono.rule, and assign OFONO_IFACE_NUM=2 for Pcui, seems it
does not work.
Here's related dmesg info:

Just suspect it is an issue in option driver.
