How to connect a mouse (and use it to capture GPS coordinates from your cell phone)?

Good luck. Be aware to use Bluetooth you have to have a WIFI or Data connection working. That might not be possible if your cell is in a backpack and may not be able to get satellite reception or a wifi or data connection :thinking: ..

Experiment. I have never tried this. I think it could work. Let us know what happens.

If you want to get very fancy with your project, you might find the information in this tutorial

useful to capture your location information to a database. The database could be the TinyDB (I did not make a version of this showing how to use a TinyDB to capture the information you want to save. It would work too.) It does not involve bluetooth.
