@crispyoz I will try this command when "pending" happens again.
Thank you

Hello, guys!
I have Omega2+, last firmware
I am setting up Wifi connection using command

/usr/bin/wifisetup add -ssid xxx -encr psk2 -password yyy

AP name and password are valid.
Very often after send connection command I have situation:

1. Omega does not receive IP address, so connection absent.

# /usr/bin/wifisetup list
{ "results": [ { "enabled": true, "ssid": "xxx", "encryption": "psk2", "password": "yyy" } ], "success": true }

# /bin/ubus call network.interface.wwan status
{
        "up": false,
        "pending": true,
        "available": true,
        "autostart": true,
        "dynamic": false,
        "proto": "dhcp",
        "device": "apcli0",
        "data": {

        }
}

# cat /etc/config/wireless

config wifi-device 'radio0'
        option type 'ralink'
        option variant 'mt7628'
        option country 'US'
        option hwmode '11g'
        option htmode 'HT40'
        option channel 'auto'
        option disabled '0'
        option device_mode 'apsta'
        option op_mode 'preference'

config wifi-iface 'ap'
        option device 'radio0'
        option mode 'ap'
        option network 'wlan'
        option ifname 'ra0'
        option encryption 'psk2'
        option key '12345678'
        option disabled '0'
        option ssid 'Omega-3079'

config wifi-iface 'sta'
        option device 'radio0'
        option mode 'sta'
        option ifname 'apcli0'
        option encryption 'psk2'
        option network 'wwan'
        option led 'omega2p:blue:wifi'
        option disabled '0'
        option ssid 'xxx'
        option key 'yyy'

config wifi-config
        option key 'xxx'
        option ssid 'yyy'
        option encryption 'psk2'

If I am rebooting Omega in this state, it succesfully connects to xxx, receives IP and all work good.

Command for disconnect:

/usr/bin/wifisetup remove -ssid xxx

removes section "config wifi-config", "config wifi-iface 'sta'" stays. Is this correct?

Main questions:
Why connection in pending state? What does it mean? How to avoid this? Or force connection?

In documentation https://docs.onion.io/omega2-docs/adjusting-ap-network-through-command-line.html I found command for restart WiFi driver "/etc/init.d/wireless restart". But it is invalid:

/# /etc/init.d/wireless restart
/bin/ash: /etc/init.d/wireless: not found

What is valid command?

Thanks

@crispyoz said in Omega2+ Wifi API:

@Pavel-Negrobov I don't know any way of actually checking the WiFi is successfully connected since UCI just changes the configuration. I just try to programatically open a connection to a known good host and check the response code.

I think to call something like '/bin/ubus call network.interface.wwan status' and check result during some timeout. For example 30 sec.

Hi, guys again.
One question stay unresolved. If I am trying to add AP with invalid password, all commands finished successfully, but connection process is

This is сontinues endlessly until I am shuts down wifi or delete AP.

How to check Wifi connection errors?

I am using UART1 (pins 45, 46) with python pyserial library without any utilities. All works good.

Thanks to all. I put all of this to my Python soft and write results here.

No, /etc/config/wireless is clean:

# cat /etc/config/wireless

config wifi-device 'radio0'
        option type 'ralink'
        option variant 'mt7628'

        option htmode 'HT40'

        option disabled '0'
        option device_mode 'apsta'
        option op_mode 'preference'

        option device 'radio0'
        option mode 'ap'
        option network 'wlan'
        option ifname 'ra0'
        option encryption 'psk2'
        option key '12345678'

        option ssid 'YourSsidHere'
        option key 'YourPasswordHere'
        option network 'wwan'
        option disabled '1'
        option led 'omega2p:blue:wifi'

okay, I can call

uci set wireless.sta.disabled='1'; uci commit wireless; wifi
uci set wireless.sta.disabled='0'; uci commit wireless; wifi

as György Farkas said.

PS.
On latest 242 build all the same.

@crispyoz said in Omega2+ Wifi API:

@Pavel-Negrobov Use network reload instead of restart, the methods stop and start don't exist, hence the error 3 response.

Restart has no effect:

Thats all. Wifi restart process does not started.
My firmware version is 0.3.2 b240. Today I will try to set the last 242 build.

@Pavel-Negrobov if you post the JSON response I can see what the issue is. Error 3 doesn't seem correct.

My router is ZyXEL Keenetic GIGA 3

@crispyoz said in Omega2+ Wifi API:

@Pavel-Negrobov please post the JSON response for the restart command. If it is returning 0 ie success, instead send network stop, pause 10 seconds, then send network start. I have seen similar issue on non-omega device where connection is maintained despite network restart when connecting to Netgear router.

Restart:

/# curl -d '{"jsonrpc": "2.0", "id": 1, "method": "call", "param
s": ["932408e95d88194879428f3b5c75ba68", "network", "restart", {}]}' http://loca
lhost/ubus
{"jsonrpc":"2.0","id":1,"result":[0]}

but network stop and network start both returns {"jsonrpc":"2.0","id":1,"result":[3]} and happens nothing.

But thank you for the previous help. Login, scan and AP add (connect) works correctly.

@György-Farkas said in Omega2+ Wifi API:

@Pavel-Negrobov If your Omega2 is running one of recent official firmwares (ie. Onion Warp Core is its WiFi driver) and connected to a WiFi network then

• disconnect from that WiFi network:
  uci set wireless.sta.disabled='1'; uci commit wireless; wifi
• (re)connect to that WiFi network:
  uci set wireless.sta.disabled='0'; uci commit wireless; wifi

Thanks. These commands are help, omega disconnects from AP after that.
