MC7455 PROBLEM

[Tang Nguyen]

AT+CGCCONTRDP replies the Bearer information which is IPv4 address.  It means your modem
has successfully registered to nework.  Problem that you have now is qmicli fails to setup a data channel bewteen host and modem.  Nothing wrong with your modem, SIM and VZ network.

Try below commands to see any help. (you migh want to add -v (verbose) option to get more debug information from libqmi commands)

qmicli -d /dev/cdc-wdm0 --wda-get-data-format
qmicli -d /dev/cdc-wdm0 --set-expected-data-format=raw-ip
qmicli -d /dev/cdc-wdm0 --wds-start-network="apn=,wxxx.vzwstatic,ip-type=4" --device-open-net="net-raw-ip|net-no-qos-header" --device-open-sync --client-no-release-cid


Above commands try to set raw-ip data link , and force connection with IPV4. APN from qmicli command must be matched with the one you get from at+cgdcont?, if not connectiion would fail.

If you got packet-data handle,  command "qmicli -d /dev/cdc-wdm0 --wds-get-current-settings" shows you the connectivity status.

 Hi Heni,
 
 
 
 Can you make sure you have below patch from Dan in your 16.2
 build.
 
 
 
 commit  4c678418f398fc5f9dcdb216c0ffdf fc8524bea2
 
 
 
 qmicli: fix handling of unspecified ip_type in
 --wds-start-network
 
 QMI_WDS_IP_FAMILY_UNSPECIFIED = 8 but ip_type gets
 initialized to 0, so the "IP Family Preference"
 was always being sent with an unrecognized value. Fixes:
 81c21379 qmicli: add support for IP type to
 --wds-start-network

  Looks like autoconnect is already enabled in your
 
  modem, and therefore
 
 
 
  you shouldn't need "WDS start network"
 (i.e.
 
  what qmi-network does).
 
 
 
  If you're having issues with auto-connect you may
 want
 
  to disable it
 
 
 
  with --wds-set-autoconnect- settings=disabled and retry
 
  with
 
 
 
  qmi-network.
