Bit=0 Bit=1 ChannelACK The frequency requested is not usable by the end-device. RX2 slot channel was successfully set RX2DataRateACK The data rate requested is unknown to the end-device. RX2 slot data rate was successfully set RX1DROffsetACK The uplink/downlink data rate offset for RX1 slot is not within the allowed range RX1 data-rate offset was successfully set Table 30: RX2SetupAns Status bits signification 1091 1092 1093 If any of the three bits is equal to 0, the command did not succeed, and the end-device SHALL 1094 keep its previous state. 1095 5.5 End-Device Status (DevStatusReq, DevStatusAns) 1096 End-devices and Network Servers SHALL implement these commands. 1097 A Network Server can use the DevStatusReq command to request status information from 1098 an end-device. The command has no payload. If a DevStatusReq is received by an end- 1099 device, it SHALL respond with a DevStatusAns command. 1100 1101 Size (octets) 1 1 DevStatusAns payload Battery RadioStatus Table 31: DevStatusAns payload format 1102 1103 1104 The reported battery level (Battery) is encoded as follows: 1105 1106 Battery Description 0 The end-device is connected to an external power source. 1..254 Battery level, where 1 is the minimum and 254 is the maximum. 255 The end-device was not able to measure the battery level. Table 32: Battery-level decoding 1107 1108 1109 The RadioStatus field contains the signal-to-noise ratio (SNR) information encoded in the 1110 six lowest bits in dB rounded to the nearest integer value for the last successfully received 1111 DevStatusReq command. It is a signed integer with a minimum value of −32 and a maximum 1112 value of 31. 1113 1114 Bits 7:6 5:0 RadioStatus RFU SNR Table 33: Status field format 1115 1116 1117
