In general, patches 1-7 look good to me.  Only one comment on patch 8.

The UC20 should be using QMI, not AT ports.  qmi_wwan support for the
UC20 has been there since 2013.  But to use it, you need to:

1) ensure qmi_wwan has been built for your kernel
2) ensure you build ModemManager with libqmi support (--with-qmi=yes)

This will solve both your problems, most likely.

RE: Failed to find primary AT port

[Jan Graczyk]

Hello Dan,

There is no problem with connecting to this modem (mini PCIe Quectel UC20 modem 
module) from kermit and sending AT commands. However when I issue the following 
commands:

 mmcli -m 0 --simple-disconnect
 mmcli -m 0 --simple-connect="pin=1234,apn=internet"

the ModemManager sends debug message "Failed to find primary AT port" to Linux 
console. However if I will power down and power up the development board the 
ModemManager starts running properly. The problem only happen when I issue the 
above disconnect and then connect command.

Best Regards,   

Jan Graczyk

What kind of modem is this?

Does it require a specific baud rate and/or serial settings?

Can you talk to the modem with 'minicom' on that port when ModemManager isn't 
running?

What kind of modem is this?

Does it require a specific baud rate and/or serial settings?

Can you talk to the modem with 'minicom' on that port when ModemManager
isn't running?

Couldn't refresh signal quality: 'Serial command timed out'

[Jan Graczyk]

Hello All,

I have a problem with getting the proper signal level from ModemManager. Here 
is the Linux console output from ModemManager -debug session:

ModemManager[1580]:  [1490979773.483400] [mm-broadband-modem.c:1991] 
modem_load_signal_quality(): loading signal quality...
ModemManager[1580]:  [1490979773.483759] [mm-port-serial.c:1237]

signal_quality_check_ready(): Couldn't refresh signal quality: 'Serial command 
timed out'

This happen when I have issued the following command to ModemManager:

mmcli -m 0 --simple-disconnect

The command:
mmcli -m 0 --simple-connect="pin=1234,apn=internet"
does not bring the ModemManager back to receive proper signal quality.
What I need to do to get ModemManager properly detecting signal quality?

In order to get ModemManager updating signal quality I needed to power down and 
power up the development board.

Best Regards,

Jan Graczyk

If it's running in MBIM mode, yes.  If it's in QMI or DirectIP, then no
(because it uses AT ports for the 3GPP registration checks and thus we
get LAC/CID with "AT+CREG=2; AT+CREG?").

AW: AW: h5321gw Problem with --location-get

[Thomas Lang]

I will check this today.
I tried a MC 7710 as well same problem --location-status gives that 3g location 
is enabled when I try --location-get I get not available. 
Does the MC 7710   have the same problem as the Ericsson one?

That is expected, because the response is processed by the unsolicited message

Do you see any 3GPP location info reported by mmcli --location-get-3gpp after 
having sent +CREG with --command?
