LoRaWAN 1.0.3 Specification ©2018 LoRa™ Alliance Page 49 of 72 The authors reserve the right to change specifications without notice. 14 Class B MAC commands 1304 All commands described in the Class A specification SHALL be implemented in Class B 1305 devices. The Class B specification adds the following MAC commands. 1306 1307 CID Command Transmitted by Short Description End- device Gateway 0x10 PingSlotInfoReq x Used by the end-device to communicate the unicast ping slot periodicity to the Network Server 0x10 PingSlotInfoAns x Used by the network to acknowledge a PingInfoSlotReq command 0x11 PingSlotChannelReq x Used by the Network Server to set the unicast ping channel frequency and data rate of an end-device 0x11 PingSlotChannelAns x Used by the end-device to acknowledge a PingSlotChannelReqcommand 0x12 BeaconTimingReq x Deprecated 0x12 BeaconTimingAns x deprecated 0x13 BeaconFreqReq x Command used by the Network Server to modify the frequency at which the end- device expects to receive beacon broadcast 0x13 BeaconFreqAns x Used by the end-device to acknowledge a BeaconFreqReq command Table 15 : Class B MAC command table 1308 14.1 PingSlotInfoReq 1309 With the PingSlotInfoReq command an end-device informs the server of its unicast ping slot 1310 periodicity. This command may only be used to inform the server of the periodicity of a 1311 UNICAST ping slot. A multicast slot is entirely defined by the application and should not use 1312 this command. 1313 1314 Size (bytes) 1 PingSlotInfoReq Payload PingSlotParam Figure 15 : PingSlotInfoReq payload format 1315 Bit# 7:3 [2:0] PingSlotParam RFU Periodicity The Periodicity subfield is an unsigned 3 bits integer encoding the ping slot period currently 1316 used by the end-device using the following equation. 1317 = 2 7− = 2 5+ 1318 The actual ping slot periodicity will be equal to 0.96 × 2 in seconds 1319
