I'm trying to connect an external antenna to the B-L475E-IOT01A1 eval board...The data sheet says that the external antenna is designed to be used with the U.FL connector...but I can't find is whether the U.FL connector is already soldered onto the board, or if I need to solder it on, and specifically where it needs to be soldered.
It looks like the data sheet is suggesting using a connector like this:

Anyone know more about this?
