Detailed Description
Stack level TX message structure.

Field Documentation
| int8_t data_rate |
Uplink datarate, if ADR is off.
Definition at line 1710 of file lorawan_data_structures.h.
| uint8_t f_buffer[MBED_CONF_LORA_TX_MAX_SIZE] |
| uint16_t f_buffer_size |
Payload size.
The size of the frame payload.
Definition at line 1743 of file lorawan_data_structures.h.
| uint8_t fport |
Frame port field. Must be set if the payload is not empty. Use the application-specific frame port values: [1...223].
LoRaWAN Specification V1.0.2, chapter 4.3.2.
Definition at line 1705 of file lorawan_data_structures.h.
| uint8_t nb_trials |
The number of trials to transmit the frame, if the LoRaMAC layer did not receive an acknowledgment. The MAC performs a datarate adaptation according to the LoRaWAN Specification V1.0.2, chapter 18.4, as in the following table:
Transmission nb | Data Rate ----------------|----------- 1 (first) | DR 2 | DR 3 | max(DR-1,0) 4 | max(DR-1,0) 5 | max(DR-2,0) 6 | max(DR-2,0) 7 | max(DR-3,0) 8 | max(DR-3,0)
Note that if nb_trials is set to 1 or 2, the MAC will not decrease the datarate, if the LoRaMAC layer did not receive an acknowledgment.
Definition at line 1731 of file lorawan_data_structures.h.
| uint16_t pending_size |
Pending data size.
Definition at line 1748 of file lorawan_data_structures.h.
| uint8_t port |
Application Port Number.
Definition at line 1692 of file lorawan_data_structures.h.
| bool tx_ongoing |
TX Ongoing flag.
Definition at line 1687 of file lorawan_data_structures.h.
Message type.
Definition at line 1697 of file lorawan_data_structures.h.
