signal_dbm does not update about luastatus HOT 12 CLOSED

Are you sure that:

1. you have the timeout option of the plugin set (to something sensible, e.g. 10), and

2. you are waiting that amount of seconds (10 in our example) before reconnecting?

from luastatus.

Also, please try i3-msg restart and report if the signal changes.

from luastatus.

Still no changes. I have timeout=10. I waited for several seconds each time I place the laptop somewhere and it does not update.

Also did i3-msg restart. Nothing happens.

from luastatus.

Here is the code:

widget = {
    plugin = 'network-linux',
    opts = {
        wireless = true,
        timeout = 10
    },
    cb = function(t)
        if not t then
            return nil
        end
        local dbm
        for iface, param in pairs(t) do
            if param.wireless then
                if param.wireless.signal_dbm then
                    dbm = param.wireless.signal_dbm
                end
            end
        end
        return {
            full_text = string.format('%s', dbm)
        }
    end
}

And also, the example wireless.lua is not updating (signal bars not changing).

from luastatus.

I waited for several seconds each time I place the laptop somewhere and it does not update.

Have you been waiting for 10 seconds?

Also did i3-msg restart. Nothing happens.

Then, the problem is in your driver, because this restarts the luastatus process (so it has no chance to cache the signal information anywhere).

And, are you sure that reconnecting updates it?

from luastatus.

Also, as an experiment, can you please launch i3status (with a config that displays wireless %quality, default will do) in the terminal and see if it changes?

from luastatus.

Have you been waiting for 10 seconds?

Yes. Minutes even just to make sure.

And, are you sure that reconnecting updates it?

Yes. By just toggling airplane mode.

i3status

I tried it. Set the global interval to 1 but still it's not changing. So I guess it really is a driver problem. Thanks!

from luastatus.

Hmm, interesting, the same is going on on my machine. cat /proc/net/wireless updates in the real time.

The code for the network-linux plugin was adapted from i3status, so there’s a bug either in:

1. i3status’ code for retrieving the wireless parameters;

2. libnl;

3. kernel driver.

I will probably investigate it later.

P.S. I’ve just found a bug in network-linux that has nothing to do with the quality not updating, but could crash the entire luastatus process when reconnecting, so please update (fixed with f403c84 commit).

from luastatus.

Also, i3status has a bug open for it: i3/i3status#106

from luastatus.

Fixed, please try now.

It's working. Thank you!
