Hello,
I am working on Telit HE910 modem.
I am using ofono 1.11, and the commit is
6e3a6156b34c52bde253b097976d0ba9dd575879.
For the Telit modem, "AT+CFUN=4" is used to enable
the modem. According to "Telit He910 AT Commands
Reference Guide", "issuing AT+CFUN=4[,0] actually
causes the module to perform either a network
deregistration and a SIM deactivation."
After this command is sent out, an unsolicited indication
"\r\n#QSS: 0\r\n" is received by of ofono. This means that
the sim card cannot be detected by the modem. It turns out
that Connman will not put the modem on line.
if "AT+CFUN=5" was used, it worked fine.
My questions are:
1. Why is "AT+CFUN=4" used to enable the modem, instead of "AT+CFUN=1"
or "AT+CFUN=5"?
2. If "AT+CFUN=4" is reasonable, are there any solutions to solve this
problem?
Thanks!
Mingli
The following is the log when "AT+CFUN=4" was used.

AT+CFUN=1 is used to set the modem online, i.e. enable RX, TX it also
enables the SIM. AT+CFUN = 4 is used to set the modem in flight mode.
I cannot see that the modem is set online in your debug output, i.e. a
D-Bus call to org.ofono.Modem.SetProperty('Online', true) is made.
Without this call you will never get an URC of #QSS with a value greater
than 0. SIM detection is enabled after AT+CFUN=1.
I never worked with ConnMan so I don't know what causes ConnMan to set
the modem online.
Try to issue
dbus-send --system --type=method_call --print-reply --dest=org.ofono
/telit_0 org.ofono.Modem.SetProperty string:'Online' variant:boolean:'true'
and see what happens (you may need to change /telit_0 to what
dbus-send --system --type=method_call --print-reply --dest=org.ofono /
org.ofono.Manager.GetModems
returns)
If this works for you, you will run into the next problem.
In /drivers/atmodem/sim.c, at_qss_notify()
case 2: /* PIN unlocked */
has to be changed to
case 3: /* SIM INSERTED and READY */
otherwise AT+CMER= ... for example will return +CME ERROR: 14 (SIM BUSY).
After a PIN has been entered, we have to wait until the modem reports
that the SIM is ready.
The above change solves the problem when a PIN is required but we have
to do something similar when no PIN is required, otherwise we will run
into the same problem.
