I added the Bosch GCY-42 Bluetooth to my drill, and spent ages trying to add it in the 360 app. I even returned it back to Amazon for a replacement, as I was sure it was dead. Nope, it turns out that when I entered my serial number, i must have mistyped it and it chose a slightly different drill. After a few weeks I noticed this and deleted it. I then searched for the asset to add via bluetooth, low and behold the drill appeared and is now working fine via the app.
So, if you can’t connect to the drill, make sure you’ve entered the right one! To be safe, maybe deleted it and add it back via a bluetooth search
