There are 3 ways to connect an antenna on this spot.
The cheapest is the wire antenna (a simple dipole) and the best option is the SMA connector.
{{ambox-stop|text=An antenna is ABSOLUTELY REQUIRED to allow any data transmission. No communication possible (even 1 meter) without antenna.}}
For testing purpose, we suggest to twist a wire inside the antenna hole (take care to not touch the ground spots with the wire).
Later on, you would focus on antenna choice:
* A wire inside the antenna hole (said a ''wire dipole'').
* A µFl connector to plug antenna.
* A PCB SMA connector also to plug other kind of antenna.
