I know my SS will work without it but it would probably work better with it.
I think it worked before I installed the new SS app on my tablet to prepare for EQ mode.
My SS works so its using the bluetooth and the SS wi-fi. Station mode is off. Will it use both at once or did I screw something up?
One thing I noticed was the SS can only be connected to one app at a time. I can't have it on my phone and the tablet at the same time.
Once you connect to your Seestar for the first time, it doesn't need Bluetooth.
If your Seestar is in range of your home WiFi network, turn on station mode. That way, you'll be connecting to it through your home WiFi network instead of directly and you will have Internet access on your phone/tablet.
You used to be able to connect multiple devices to the Seestar at the same time, but not anymore.
My telescopes have trouble connecting to my WiFi when they're outdoors, because of the location of my access point. I have an extender that serves to both extend my WiFi network and has a hardwired ethernet port to plug in the ASIAir on my other telescope. You might consider something like that.
