Function Documentation

◆ lorawan_deinit()

void lorawan_deinit ( void )

Deinitialize LoRaWAN handler.

◆ lorawan_get_status()

lorawan_status_t lorawan_get_status ( void )

Get current LoRaWAN status.

Returns: Current status

◆ lorawan_init()

int lorawan_init ( void )

Initialize the LoRaWAN handler.

Initializes SPI, configures the SX1276, and prepares for OTAA join.

Returns: ESP_OK on success, error code otherwise

◆ lorawan_is_joined()

bool lorawan_is_joined ( void )

Check if device has joined the network.

Returns: true if joined, false otherwise

◆ lorawan_join()

int lorawan_join ( void )

Start OTAA join procedure.

Attempts to join The Things Network using OTAA. This is a non-blocking call - use lorawan_get_status() to check progress.

Returns: ESP_OK if join request sent, error code otherwise

◆ lorawan_process()

void lorawan_process ( void )

Process LoRaWAN events (call periodically from main loop)

This should be called regularly to process radio events.

◆ lorawan_send()

int lorawan_send	(	uint8_t	port,
		const uint8_t *	data,
		uint8_t	len,
		bool	confirmed
	)

Send data uplink to TTN.

Parameters

port	LoRaWAN port (1-223)
data	Pointer to data buffer
len	Length of data (max 51 bytes for SF7-SF12)
confirmed	Whether to request confirmation (ACK)

Returns: ESP_OK if data queued for sending, error code otherwise

◆ lorawan_set_tx_done_callback()

void lorawan_set_tx_done_callback ( lorawan_tx_done_cb_t callback )

Set callback for TX complete event.
