Enumeration Type Documentation

telemetry_type_t

enum telemetry_type_t

Edgehog telemetry types.

This enum is used for configuring the telemetry type in edgehog_device_telemetry_config_t struct.

Enumerator
EDGEHOG_TELEMETRY_INVALID	The telemetry type is invalid.
EDGEHOG_TELEMETRY_HW_INFO	The hardware info telemetry type.
EDGEHOG_TELEMETRY_WIFI_SCAN	The wifi scan telemetry type.
EDGEHOG_TELEMETRY_SYSTEM_STATUS	The system status telemetry type.
EDGEHOG_TELEMETRY_STORAGE_USAGE	The storage usage telemetry type.
EDGEHOG_TELEMETRY_BATTERY_STATUS	The battery status telemetry type.
EDGEHOG_TELEMETRY_GEOLOCATION_INFO	The geolocation info telemetry type.

Function Documentation

edgehog_device_astarte_event_handler()

void edgehog_device_astarte_event_handler	(	edgehog_device_handle_t	edgehog_device,
		astarte_device_data_event_t *	event )

receive data from Astarte Server.

This function must be called when an Astarte Data event coming from server.

Parameters

edgehog_device	A valid Edgehog device handle.
event	A valid Astarte device data event.

edgehog_device_destroy()

void edgehog_device_destroy

(

edgehog_device_handle_t

edgehog_device

)

destroy Edgehog device.

This function destroys the device, freeing all its resources.

Parameters

edgehog_device

A valid Edgehog device handle.

edgehog_device_new()

edgehog_device_handle_t edgehog_device_new

(

edgehog_device_config_t *

config

)

create Edgehog device handle.

This function creates an Edgehog device handle. It must be called before anything else.

Example: astarte_device_handle_t astarte_device = astarte_device_init();

edgehog_device_config_t edgehog_conf = { .astarte_device = astarte_device, };

edgehog_device_handle_t edgehog_device = edgehog_device_new(&edgehog_conf);

Parameters

config

An edgehog_device_config_t struct.

Returns

The handle to the device, NULL if an error occurred.

edgehog_device_set_system_part_number()

esp_err_t edgehog_device_set_system_part_number	(	edgehog_device_handle_t	edgehog_device,
		const char *	part_num )

set the system part number

This function sends the system part number on Astarte and stores it on the nvs.

Parameters

edgehog_device	A valid Edgehog device handle.
part_num	The part number to be stored

Returns

ESP_OK if the data was successfully stored and sent, an esp_err_t otherwise.

edgehog_device_set_system_serial_number()

esp_err_t edgehog_device_set_system_serial_number	(	edgehog_device_handle_t	edgehog_device,
		const char *	serial_num )

set the system serial number

This function sends the system serial number on Astarte and stores it on the nvs.

Parameters

edgehog_device	A valid Edgehog device handle.
serial_num	The serial number to be stored

Returns

ESP_OK if the data was successfully stored and sent, an esp_err_t otherwise.

edgehog_device_start()

edgehog_err_t edgehog_device_start

(

edgehog_device_handle_t

edgehog_device

)

start Edgehog device.

This function starts the device, enabling the telemetry update if configured.

Parameters

device

A valid Edgehog device handle.

Returns

EDGEHOG_OK if the device was successfully started, another edgehog_err_t otherwise.
