Dongle Configuration

No configuration is required on the Dongle for LXNAV. Simply plug it into the PDA port, start the flight instrument, enable its Bluetooth module and Naviter BT Dongle will become visible after a few seconds. The moment it becomes visible as a Bluetooth device, it is ready to transmit data over Bluetooth Low Energy and Bluetooth 2.0 protocols.

LXNAV Configuration

  • LXNAV device must have NMEA output enabled in Settings > Hardware > Comm.
  • PDA Bauderate on the same page must be set 115200 bps or less (19200 is recommended. Slower speed is more reliable and has greater reach)
  • Dongle must be connected directly to the PDA port on the back of the LXNAV device. If it is not, full functionality is not guaranteed.
  • LXNAV device must have good GPS reception when you test. If it didn’t have good GPS for several minutes, turn it off and on in a place where it will have good GPS quickly.

Renaming the Dongle

In an environment where several dongles are visible to SeeYou Navigator, such as in the club and at a competition, giving your Dongle a unique name is a good idea. Renaming the Naviter Bluetooth Dongle is easy with SeeYou Navigator.
