Detailed Description
Stack level TX message structure.
Definition at line 855 of file lorawan_data_structures.h.
Field Documentation
| int8_t data_rate |
Uplink datarate, if ADR is off.
Definition at line 883 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 926 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 878 of file lorawan_data_structures.h.
| uint8_t nb_trials |
For CONFIRMED Messages:
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.
For UNCONFIRMED Messages:
Provides a certain QOS level set by network server in LinkADRReq MAC command. The device will transmit the given UNCONFIRMED message nb_trials time with same frame counter until a downlink is received. Standard defined range is 1:15. Data rates will NOT be adapted according to chapter 18.4.
Definition at line 914 of file lorawan_data_structures.h.
| uint16_t pending_size |

Definition at line 931 of file lorawan_data_structures.h.

Definition at line 865 of file lorawan_data_structures.h.
| bool tx_ongoing |
TX Ongoing flag.
Definition at line 860 of file lorawan_data_structures.h.
