@jthirasilpa weird…

the trace shows, on a timer tick (in the modulename.js) the node+helper received a socket message (sendSocketNotification from modulename.js), and received in node_helper)
the notification is correct, and it starts to rescan the network…

but, it has lost the config pointer for some reason…

weird…

please do another git pull

also add debug:true,

to the module config section

let me know

thanks

Thanks. Scan seems to find some devices, but does not display them on Mirror.

jojo isn’t in the configured list above… so, did u change the config?

and it says it will scan all the addresses in the devices list, but millie isn’t pinged…

what else do you have in bottom_center? it can get pushed off screen pretty easily…

jthirasilpa · Feb 23, 2020, 10:05 PM

Thanks - I did change the config to add one device “JoJo” with an IpAddress and I changed “Millie” from IpAddress to MacAddress (I am guessing that is why it is not showing in the ping result - but am not sure). I did not make any other changes to the config (apart from adding the debug line). There is no other bottom_center module and it clearly displays Devices Online “Loading…”, so I don’t think it’s the case that entries are being pushed off the page.

@jthirasilpa do you have arp-scan installed?

Open a terminal window and type

sudo arp-scan

If not install it. Not part of module.

sudo apt-get install arp-scan

todro · Feb 24, 2020, 1:52 AM

@sdetweil
Problem is the fact that the CONFIG message is sent from the frontend only at the loading of the page (subclassing START). If the page is still open in the browser it will send SCAN_NETWORK requests periodically which will lead to the situation where the config object is empty when the scan is to be executed, if the service has been restarted meanwhile.

Furthermore, if a reload of the page is executed, a CONFIG request is sent to NODE_HELPER which might be busy scanning and it seems as if there is no escape unless the correct sequential order for CONFIG and SCAN_NETWORK is used.

To verify:

1.) Stop loading of the page in browser or navigate to an other page so no SCAN_NETWORK will be created for the device status updates
2.) Stop + restart MM
3.) Reload page / enter start URL

This will lead to the correct order and the programmatic solution is to check if the config object is filled before executing the scan. If not, it has to be reloaded, the CONFIG request in NODE_HELPER can not be used as it uses the payload from the frontend.

sdetweil · Feb 24, 2020, 4:19 PM

@todro oh yeh that will be a mess. Hadn’t thought of that, electron will shutdown, but remote page wont

That will be a problem for many modules!

@jthirasilpa ok. Need to open the developers console, ctrl-shift-i on the keyboard, select the console tab and scroll up to see any errors.

U can also filter by module, by putting part of the module name in the filter field. Network, for example.

The code should be sending messages to the module name.js
