Can I connect devices with Bluetooth?
Yes this is supported.
When a device has been paired with your computer, virtual serial ports will be created on your system.
They will be called something like "Standard serial port over Bluetooth link #1".
Just check which "COMxx" port is associated with the serial port, and use this to configure the device in Hydromagic.
We tested this with several devices allready, including Trimble RTK receivers and the Ohmex BTX Bluetooth echosounder.
