Notes.

  • Wired connection via USB
    Some smartphones and tablets may not allow USB connection or may limit the power supply to the smartphone or tablet itself. This depends on the specifications of the phone or tablet, and we cannot provide support for this.

  • Wireless connection via Bluetooth
    It can be used stably with less connection and power supply problems with smartphones and tablets.Bluetooth wireless connection is recommended for use with AgriBus-NAVI. It is also possible to connect a Bluetooth/serial converter (e.g. RATOC REX-BT60) to a GNSS receiver that supports RS232C output.
