Or so it the git way: first create a branch and then make your changes. Any updates from the master will then not overwrite your changes.

Yesterday i added a feature to the scripts that I have wanted for my SBCs for awhile. I configured it so that it would attempt to connect to any known wifi networks first, but then if it doesnt succeed after a certain time delay, to host one of its own wifi hotspots instead. Please try it out

Hi,

3 questions here.....

1. Do I need to unplug the LAN cable just to test out this feature?
2. Do I need to check the "Connect automatically with priority" option in Wi-Fi configuration?
3. Do I need to at least hook up to one of my home wifi networks to test out this feature?

In my mind, I am expecting 30sec after my Pi boot up completely, if no home networks detected or no wifi point connected then pi hotspot will kick in right after that. Is this the correct process?
If yes, that's mean this will delaying the pi hotspot to start. Am I right?

BTW, I prefer 2.4G become the priority. :) Which I can change in Wi-Fi configuration.

Regards,
Tom

1. No the LAN cable is not relevant. Plugging it into your laptop directly could help you see what is happening. Disconnecting your wifi network or going somewhere beyond its range though would be necessary.

2. Are you talking about for your own home wifi network here? My script should have already done that for the field wifi if you chose to use this new feature. And yes, all your normal wifi networks should be setup to connect autommatically with priority 0 or higher.

3. Yes i would hook it up to your home wifi with the connect automatically feature turned on. Then i would try turning the pi on with the wifi network online, then try turning the pi on with the network offline, and then i would try disconnecting the home wifi while the pi is online to see if it switches over.

Yes this would delay the hotspot starting by however long the delay is set to, because it would need to test the home wifi networks first before giving up.

Yes you can change the priority numbers how you like, but make sure the field wifi is below all other wifi. The default value for networks is zero, so i just made field wifi negative. I set it to prefer 5 GHz because of the faster thoroughput. But i still have the 2.4 GHz option in the list because there is no way to know if the user has or will have 5 GHz. It is currently set to try 5 GHz first and it doesnt work, then try 2.4.

Thanks for the explanation. But I found out after I disconnect the home wifi, the field_hotspot taking forever to take over. Looks like it never automatically swap to field_wifi. :(

Edit: It works actually. But if the home wifi comes back, will it connect back to the home wifi??? I tried, it won't. :(

No there wouldn’t be an easy way to make it go back. Basically I made the hotspot the last resort, if it can’t connect, try hosting a hotspot last.

You wouldn’t actually want it to switch back automatically though. If you have an observing session set up and running, and the WiFi switched to hotspot and back again, it would disconnect you since the IP address would change. If you are just connecting with VNC that isn’t a huge problem but if you are imaging with a remote client It would probably disconnect the session.

So really the way I see this working is that if you are at home, it finds the home network and you use that, if you are in the observing field, it doesn’t find the home network and hosts the hotspot.

A sort of beneficial side effect is that if the home WiFi goes down it hosts the hotspot also, but that wasn’t the intent and it wouldn’t actually be good for that to happen during remote imaging as I said.

I will play with this some more. There might be some other ways to improve it, but for now I think this is better than the prior configuration.

Just tried this and seems to work well, but I did disconnect it from my home WiFi but it did not start the hotspot... is this correct..?

Also where can I alter the default 30 seconds to search...?

I had been using a second WiFi dongle and having home WiFi on that, and hotspot on the internal..that seemed to work well, I also added a file to autostart to start the hotspot at boot..

After running your script again to install these new WiFi upgrades, I just opened Kstars and it’s broken, it opens, then when I click ekos it brings up a window that says:

“An instance of INdI server is already open, do you want to close before opening another”

and no matter if I click yes or no it just shuts Kstars completely down every time...
Any ideas..

It is possible there was a change in KStars. My script wouldn’t change it, but it does install the latest KStars

Are you running another INDI server such as with INDI Web Manager App, INDI web manager, or as a service?

You can always try quitting those. Or from the command line killall indiserver
