Bluetooth IoT Gateway with Pi

[sbenavides]

Anyone got a good recommendation for adding bluetooth with External antenna to Raspberry Pi WITHOUT manipulating an existing board/module/soldering? Working on IoT Gateway for bluetooth beacons to forward data to backend via Pi

Nope.. there are no connections for an external antenna, and trying to do it by hand would be an exercise in blind guessing if you don't have a circuit analysis package that can model RF systems. At high frequencies, the wires are more like resonating chambers than conductors, so every physical dimension matters.
