If using the over-the-air activation procedure, the end-device should broadcast the JoinReq 1 message on a random 125 kHz channel amongst the 96 uplink channels defined using DR5 2 to DR0. 3 Personalized devices shall have all 96 channels enabled following a reset. 4 5 2.6.3 CN470-510 Data Rate and End-point Output Power encoding 6 There is no dwell time limitation for the CN470-510 PHY layer. The TxParamSetupReq 7 MAC command does not have to be implemented by CN470-510 devices. 8 The following encoding is used for Data Rate (DR) and End-point Output Power (TXPower) 9 in the CN470-510 band: 10 11 DataRate Configuration Indicative physical bit rate [bit/sec] TXPower Configuration 0 LoRa: SF12 / 125 kHz 250 0 17 dBm 1 LoRa: SF11 / 125 kHz 440 1 16 dBm 2 LoRa: SF10 / 125 kHz 980 2 14 dBm 3 LoRa: SF9 / 125 kHz 1760 3 12 dBm 4 LoRa: SF8 / 125 kHz 3125 4 10 dBm 5 LoRa:SF7 / 125 kHz 5470 5 7 dBm 6 5 dBm 6:15 RFU 7 2 dBm 8…15 RFU Table 34: CN470 Data rate and TX power table 12 2.6.4 CN470-510 JoinResp CFList 13 The CN470-510 LoRaWAN does not support the use of the optional CFlist appended to the 14 JoinAccept message. If the CFlist is not empty it is ignored by the end-device. 15 2.6.5 CN470-510 LinkAdrReq command 16 For the CN470-510 version the ChMaskCntl field of the LinkADRReq command has the 17 following meaning: 18 19 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 Channels 80 to 95 6 All channels ON The device should enable all currently defined channels independently of the ChMask field value. 7 RFU Table 35: CN470 ChMaskCntl value table 20 If the ChMask field value is one of the values meaning RFU, then end-device should reject 21 the command and unset the "Channel mask ACK" bit in its response. 22
