Detailed Description

GNSS RTK 4 Click Example.

Description

This example demonstrates the use of GNSS RTK 4 Click by reading and displaying the GNSS coordinates.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

Application Task

Reads the received data, parses the NMEA GGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.

Additional Function

  • static void gnssrtk4_clear_app_buf ( void )
  • static void gnssrtk4_log_app_buf ( void )
  • static err_t gnssrtk4_process ( gnssrtk4_t *ctx )
  • static void gnssrtk4_parser_application ( uint8_t *rsp )
Note
The Click board comes with the default baud rate of 460800, but the baud rate is set to 115200 in the library due to code portability and speed limitations of some MCUs. So in order to run the example you will need to adjust the baud rate using Quectel QGNSS evaluation software.

Logger initialization. Default baud rate: 115200 Default log level: LOG_LEVEL_DEBUG

Note
If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
