Noob with a few minor questions

Hi @Daveysawyer and welcome to the forum.

I think you’ll have more fun with the tablets than your children

When you get a 404 error, the (mock) URL you opened does not get routed to the meshtastic app. I suppose you sent the URL to the other tablet via some messenger? When you click on that URL, the meshtastic app should start and ask you if you want to change the channel. Entering the URL into a browser manually won’t work, because this bypasses the Android App Links system.
If your browser starts on clicking the URL, you probably would reset the standard apps setting of your browser.

See here:

Would you like your device's BLE link to not go to sleep? do this

A number of people have asked for this feature. It is coming to the android in the next weekish, but you can do it now with the python tool. Here’s an example: You can also use this tool to set any of the device parameters which are stored in persistent storage. For instance, here’s how to set the device to keep the bluetooth link alive for eight hours (any usage of the bluetooth protcol from your phone will reset this timer) pip3 install --upgrade meshtastic meshtastic --setpref wait_blu…

A feature to change this via app settings will be added soon.

Hope that helps, but if you need some more help, feel free to ask.
