Re: SMS sending error with Telit module

When I try to send an SMS when connected (with MM 5.2), I get an error like "cannot send an SMS while connected" (maybe connection is made using only one USB port?). If data connection is not active, I still cannot send SMS, as explained in previous post...

I've attached two debug logs, one from MM 5.2 (startup + successful data connection), one from MM7.99 ("failed" startup, so I cannot make data connection/SMS sending tests).

I will try to make some debugging logs.

Side question: my modem module uses 3 USB ports: one for commands, one 
for commands/data and one reserved for firmware upgrade.
ModemManager manages (and locks?) the first two ports. Is there a way to 
send AT commands  to the modem "thru" ModemManager?
Or alternatively, to configure ModemManager to use only one port (the 
one for commands/data) and leave the other port free?
I ask this because I need to send SMS also when data connection is 
active, and I'm not sure if ModemManager allows this...
ModemManager definitely allows this, as long as it can find 2 or more
ports.  It sounds like this is the case for your device, so I would
expect SMS to work fine when the data port is busy with PPP.


Thank you

Are you able to test this with MM git master?

Marius: There is already a PPA with MM git master, right?
For Raring:

For Quantal, I think my PPA will work:


networkmanager-list mailing list
networkmanager-list gnome org
