◆ LoRaWAN_SendConfirmedData()

LmHandlerErrorStatus_t LoRaWAN_SendConfirmedData	(	uint8_t *	data,
		uint8_t	dataSize,
		uint8_t	port )

static

Send confirmed data to LoRaWAN network.

This function sends data that requires acknowledgment from the server. The server must respond with a downlink acknowledgment. This is useful for critical data that must be verified as received.

Parameters

data	Pointer to the data buffer to send
dataSize	Size of the data in bytes (max 242 bytes)
port	LoRaWAN application port (typically 2)

Returns

LmHandlerErrorStatus_t Status of the send operation

LORAMAC_HANDLER_SUCCESS: Data queued for transmission with confirmation
LORAMAC_HANDLER_ERROR: Failed to queue data
LORAMAC_HANDLER_BUSY_ERROR: MAC layer is busy
LORAMAC_HANDLER_NO_NETWORK_JOINED: Not connected to network

void OnLoRaWanConnected ( void )

Called after LoRaWAN successfully connects to the server.

This function is called when the LoRaWAN join process completes successfully. It performs time synchronization with the LoRaWAN server by requesting the device time, which updates the RTC with the server's time.

Handle received downlink data from LoRaWAN server.

This callback function is triggered when the device receives data from the LoRaWAN server. This can be a response to a confirmed uplink or an application-level downlink message.

Parameters

appData	Received application data including buffer and port
params	Receive parameters including RSSI, SNR, and downlink counter

Handle transmission event callback.

This callback is triggered after a transmission attempt, whether successful or not. It provides information about whether an ACK was received for confirmed messages.

Parameters

params Transmission parameters including status and ACK received flag

◆ OnTimeSynchronized()

void OnTimeSynchronized ( void )

Called after date/time has been synchronized from LoRaWAN.

This function is called when the device receives a time synchronization response (DeviceTimeAns) from the LoRaWAN server. The RTC has already been updated with the server's time when this function is called.

Add your custom code here to perform actions after time synchronization, such as updating time-dependent schedules, logging the sync event, or triggering time-based operations.
