Detailed Description

GNSSMAX Click Example.

Description

This example showcases device abillity to read data outputed from device and show it's coordinates and altitude when connected.

The demo application is composed of two sections :

Application Init

Initializes host communication modules, additioaln GPIO's used for control of device and resets device.

Application Task

Reads data from device and wait's untill device is connected. While not connected it will log '.'. When conneceted and received data for latitude, longitude, and altitude it will log that data parsed from "GNGGA" command.

Additional Function

static void gnssmax_clear_app_buf ( void )
static err_t gnssmax_process ( void )
static err_t gnssmax_cmd_parser ( char *cmd )
static err_t gnssmax_element_parser ( char *cmd, uint8_t element, char *element_data )

Note: For the device to connect it can take it from 1 to 10 minutes. Time to connect is depending on weather.
