Detailed Description

LoRaMAC MCPS-Request for a confirmed frame

Field Documentation

fPort

uint8_t sMcpsReqConfirmed::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

fBuffer

void* sMcpsReqConfirmed::fBuffer

Pointer to the buffer of the frame payload

fBufferSize

uint16_t sMcpsReqConfirmed::fBufferSize

Size of the frame payload

Datarate

int8_t sMcpsReqConfirmed::Datarate

Uplink datarate, if ADR is off

NbTrials

uint8_t sMcpsReqConfirmed::NbTrials

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, according to 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 NbTrials is set to 1 or 2, the MAC will not decrease the datarate, in case the LoRaMAC layer did not receive an acknowledgment
