ST / Mbed OS TeseoLocation

Teseo Location demo for GPSProvider using ST GNSS driver.

Dependencies:   GPS_Provider X_NUCLEO_GNSS1A1

Getting Started with X-NUCLEO-GNSS1A1

This example demonstrates how to use the X-NUCLEO-GNSS1A1 component with one of the STM32 Nucleo-64 platforms and how real time GNSS data received by the Teseo-LIV3F device can be displayed through a serial connection and a serial terminal on a PC. Furthermore the user can run commands enabling three advanced features:

  • Geofencing
  • Odometer
  • Data Logging

Setup

Once the antenna has been connected to the SMA female connector of the X-NUCLEO-GNSS1A1 plugged on top of the STM32 Nucleo, a serial connection should be set up between the STM32 Nucleo and the PC with the following parameters:

  • baud rate: 115200
  • data: 8 bit
  • parity: none
  • stop: 1bit
  • flow control: none
  • New-line (Tx/Rx): CR

Serial connection parameters

The user can select among different options to:

  • get in a human readable format information related to the acquired GNSS position (or the satellites in view, the active satellites, and so on)
  • enable feature (geofencing, odometer, data logging)
  • configure a geofence circle
  • require geofence status
  • start/stop feature (odometer, data logging)
