BlueSolar MPPT 75/15 jumper question

I am completely new to all of this. I've purchased a travel trailer that has this controller; don't yet have solar panels. It came with what I learned is a jumper, inserted where I will need to plug the BlueTooth dongle.

Can someone please explain to me what the jumper is for, when I might need it, and how will that work once I get the Bluetooth dongle and it is plugged in there? Or is it something I insert and then that does something?

Sorry for what must seem like dumb questions, but I really don't understand this at all.

picture below -- it's rotated for some reason. Shows the jumper's original placement. Now it is out, taped to my manual.

Yes remove the link as then you can do all your settings inside the Victron Connect APP

Oh good, I’m hoping I will understand the app better than physical jumpers. Plus the dongle has to plug in there anyway.

Hello! I have the same questions about the use of the jumper. Am I correct in interpreting the above messages to say that the jumper is not necessary and that the controller would operate normally (default) with the jumper not in place? Also, can anyone explain the effects of the different jumper settings? Thank you very much for your help!

My understanding is you can Discard the jumper if you reprogram with a dongle.

The 3 jumper settings are shown in the manual but not explained very well, I do not understand the options.
