ubuntu - NMCLI device unavailable -


i trying configure new unit cellular interface on ubuntu core 16.04. have nmcli package running on it. before added connection checked interfaces

# nmcli dev device    type      state         connection          eth1      ethernet  connected     wired connection 1  wlan0     wifi      disconnected  --                  eth0      ethernet  unavailable   --                  cdc-wdm0  gsm       unavailable   --                  lo        loopback  unmanaged     --

i added connection:

nmcli con add type gsm ifname cdc-wdm0 con-name myconnection apn myapn.com

finally have tried bringing connection running: 

nmclil con myconnection  error: connection activation failed: no suitable device found connection

also have pasted output of config applied:

# nmcli -p con show myconnection                    connection profile details (myconnection)  connection.id:                          myconnection connection.uuid:                        25dc3eec-ca8a-4861-bfcc-089d558972d4 connection.interface-name:              cdc-wdm0 connection.type:                        gsm connection.autoconnect:                 yes connection.autoconnect-priority:        0 connection.timestamp:                   0 connection.read-only:                   no connection.permissions:                  connection.zone:                        -- connection.master:                      -- connection.slave-type:                  -- connection.autoconnect-slaves:          -1 (default) connection.secondaries:                  connection.gateway-ping-timeout:        0 connection.metered:                     unknown connection.lldp:                        -1 (default)  ipv4.method:                            auto ipv4.dns:                                ipv4.dns-search:                         ipv4.dns-options:                       (default) ipv4.addresses:                          ipv4.gateway:                           -- ipv4.routes:                             ipv4.route-metric:                      -1 ipv4.ignore-auto-routes:                no ipv4.ignore-auto-dns:                   no ipv4.dhcp-client-id:                    -- ipv4.dhcp-timeout:                      0 ipv4.dhcp-send-hostname:                yes ipv4.dhcp-hostname:                     -- ipv4.dhcp-fqdn:                         -- ipv4.never-default:                     no ipv4.may-fail:                          yes ipv4.dad-timeout:                       -1 (default)  ipv6.method:                            auto ipv6.dns:                                ipv6.dns-search:                         ipv6.dns-options:                       (default) ipv6.addresses:                          ipv6.gateway:                           -- ipv6.routes:                             ipv6.route-metric:                      -1 ipv6.ignore-auto-routes:                no ipv6.ignore-auto-dns:                   no ipv6.never-default:                     no ipv6.may-fail:                          yes ipv6.ip6-privacy:                       -1 (unknown) ipv6.addr-gen-mode:                     stable-privacy ipv6.dhcp-send-hostname:                yes ipv6.dhcp-hostname:                     --  gsm.number:                             *99# gsm.username:                           <hidden> gsm.password:                           <hidden> gsm.password-flags:                     0 (none) gsm.apn:                                myapn.com gsm.network-id:                         -- gsm.pin:                                <hidden> gsm.pin-flags:                          0 (none) gsm.home-only:                          no gsm.device-id:                          -- gsm.sim-id:                             -- gsm.sim-operator-id:                    --

my question how enable unavailable device , why unavailable? can check me resolve issue.

any great starting on snappy.

ok, managed resolve own problem, steps took follows:

1) check modem on gateway read ubuntu core:

$ sudo mmcli -l  found 1 modems:     /org/freedesktop/modemmanager1/modem/0 [generic] mbim [1519:0020]

2) check sim read correctly:

$ sudo mmcli -m 0  /org/freedesktop/modemmanager1/modem/0 (device id 'd8b328efa783ca35a022d6b44b878981e67a5903')   -------------------------   hardware |   manufacturer: 'generic'            |          model: 'mbim [1519:0020]'            |       revision: 'mod_6260_v05.1412.00_r07_vctcx'            |      supported: 'gsm-umts'            |        current: 'gsm-umts'            |   equipment id: '014752000020933'   -------------------------   system   |         device: '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3'            |        drivers: 'cdc_acm, cdc_mbim'            |         plugin: 'generic'            |   primary port: 'cdc-wdm0'            |          ports: 'cdc-wdm0 (mbim), wwan0 (net), ttyacm0 (at)'   -------------------------   numbers  |           own : 'unknown'   -------------------------   status   |           lock: 'none'            | unlock retries: 'sim-pin (3)'            |          state: 'connected'            |    power state: 'on'            |    access tech: 'gprs'            | signal quality: '67' (cached)   -------------------------   modes    |      supported: 'allowed: 2g, 3g; preferred: none'            |        current: 'allowed: 2g, 3g; preferred: none'   -------------------------   bands    |      supported: 'unknown'            |        current: 'unknown'   -------------------------   ip       |      supported: 'ipv4, ipv6, ipv4v6'   -------------------------   3gpp     |           imei: '<censored>'            |  enabled locks: 'fixed-dialing'            |    operator id: '27203'            |  operator name: 'irl - meteor'            |   subscription: 'unknown'            |   registration: 'home'   -------------------------   sim      |           path: '/org/freedesktop/modemmanager1/sim/0'    -------------------------   bearers  |          paths: '/org/freedesktop/modemmanager1/bearer/0'

this realised sim has not been found in gateway , have damaged sim, have changed sim card , came output above.

3) configure new apn or edit existing one. (i found easier add connection anew)

make sure in root (sudo su -)

a)delete existing connection failing

 #nmcli con delete myconnection

b)create new connection 

#nmcli con add type gsm ifname cdc-wdm0 con-name myworkingconnection apn mynewapn.com

4) add username , password new connection

#nmcli con edit myworkingconnection

at point in nmcli> prompt. type in help list of commands edit connection. me needed add username , password achieved typing in:

nmcli> set gsm.username data nmcli> set gsm.password <passwordgoeshere> nmcli> save nmcli> quit

at point connection has established. have found command 

#nmcli m

open in session being useful check state of interface changing.

hope helps people!

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
