I have a HC-06 Bluetooth module installed in the VNA.
My Galaxy 10S sees and pairs with the modual with no problem.
However, I have not found any software for the VNA, Windows or android, that works with a Bluetooth connection.
I have the VNA-APP ou refered to, however, I have not find anywhere in settings or elsewhere, it set the connection to Bluetooth.
I am still hoping for software for that can use Bluetooth on a Android smartphone. It is easier to pack a cellphone than a PC when installing an antenna on a tower, pole or tree.
When using the VNA, in the house or shack, I have found no problem with USB connections.
It would just make things easier to use wireless instead of wired connections.
Thanks,
