If the end-device will never operate with a repeater, the maximum application payload length 1044 in the absence of the OPTIONAL FOpts control field SHALL be: 1045 1046 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 250 242 5 250 242 6 250 242 7 250 242 8..11 Not defined 12 250 242 13 250 242 14..15 Not defined Table 37: EU433 maximum payload size (not repeater compatible) 1047 3.7.7 EU433 Receive Windows 1048 By default, the RX1 receive window uses the same channel as the preceding uplink. The data 1049 rate is a function of the uplink data rate and the RX1DROffset, as given by the following 1050 table. The allowed values for RX1DROffset are in the [0:5] range. Values in the range [6:7] 1051 are reserved for future use and end-devices SHALL NOT accept these settings in any 1052 command, neither a RXParamSetupReq, which SHALL cause a negative acknowledgement 1053 of RX1DROffsetACK in RXParamSetupAns, nor a Join-Accept which SHALL be silently 1054 ignored. 1055 1056 Upstream Data Rate Downstream Data Rate RX1DROffset 0 1 2 3 4 5 DR0 DR0 DR0 DR0 DR0 DR0 DR0 DR1 DR1 DR0 DR0 DR0 DR0 DR0 DR2 DR2 DR1 DR0 DR0 DR0 DR0 DR3 DR3 DR2 DR1 DR0 DR0 DR0 DR4 DR4 DR3 DR2 DR1 DR0 DR0 DR5 DR5 DR4 DR3 DR2 DR1 DR0 DR6 DR6 DR5 DR4 DR3 DR2 DR1 DR7 DR7 DR6 DR5 DR4 DR3 DR2 DR12 DR12 DR5 DR4 DR3 DR2 DR1 DR13 DR13 DR12 DR5 DR4 DR3 DR2 Table 38: EU433 downlink RX1 data rate mapping 1057 The RX2 receive window uses a fixed frequency and data rate.
