The ChMaskCntl field of the LinkADRReq command has the following meaning: 1027 1028 ChMaskCntl ChMask Applies To 0 Channels 0 to 15 1 Channels 16 to 31 2 Channels 32 to 47 3 Channels 48 to 63 4 Channels 64 to 79 5 10 LSBs control channel blocks 0 to 9, 6 MSBs are RFU 6 All channels ON: The device SHALL enable all currently defined channels regardless of the ChMask field value. 7 RFU Table 35: EU433 ChMaskCntl value 1029 If ChMaskCntl = 5, the corresponding bits in the ChMask enable and disable a bank of eight 1030 channels defined by the following calculation: [ChannelMaskBit * 8, ChannelMaskBit * 8 1031 +7]. 1032 If the ChMask field value is RFU, the end-device SHALL 4 reject the command and unset the 1033 Channel mask ACK bit in its response. 1034 3.7.6 EU433 Maximum Payload Size 1035 The maximum MACPayload size length (M) is given by the following table. It is derived from 1036 a limitation of the PHY layer, depending on the effective modulation rate used, taking into 1037 account a possible repeater encapsulation layer. The maximum application payload length in 1038 the absence of the OPTIONAL FOpts control field (N) is also given for information only. The 1039 value of N might be smaller if the FOpts field is not empty. 1040 1041 Data Rate M N 0 59 51 1 59 51 2 59 51 3 123 115 4 230 222 5 230 222 6 230 222 7 230 222 8..11 Not defined 12 230 222 13 230 222 14..15 Not defined Table 36: EU433 maximum payload size (repeater compatible) 1042 1043
