Data analysis example for JavaScript:
function decodeUplink(input) { var obj = {}; var warnings = []; var len = input.bytes ? input.bytes.length : 0; var offset = 0, dtype = 0, dlen = 0;
.
do { dtype = input.bytes[offset++]; if (0xFF == dtype) { /* 0xFF is ACK from Device */ obj.ackcmd = input.bytes[offset++]; obj.ackstatus = input.bytes[offset++]; } else if (0x00 === dtype) { /* first is device information(0x00) */ obj.battery = (input.bytes[offset++] & 0x1F); obj.res = input.bytes[offset++]; } else if (0x01 == dtype) { offset += 8; } else if (0x02 == dtype) { offset += 8; } else if (0x03 == dtype) { offset += 2; } else if (0x04 == dtype) { /* temperature sensor, value unit is 0.1 */

3. Wireless LoraWAN Sensor Data Format
LoRaWAN Format: Picture as below, FRMPayload is sensor data.
4. Sensor Data Definition
4.1 Multi-temperature0x14
Adapt N-way temperature according to length, and if N is 1, the basic temperature type 0x04 can be directly used. If N>1 channel temperature needs to be transmitted, merge similar data items in the following order.
Type 1 Byte 0x14
Length 1 Byte
2*N
Value int16_t No.1 temp
Value ... ...
Value int16_t No. N temp
4.2 Multi-humidity0x15
According to the length, N channels of humidity can be adapted. If N is 1, the basic humidity type 0x05 can be directly used. If N>1 channel of humidity needs to be transmitted, merge similar data items in the following order.
Type 1 Byte 0x15
Length 1 Byte
N
Value uint8_t No. 1 humi
Value ... ...
Value uint8_t No. N humi
FRMPayload Example: 007F101404033C033A15024445 00 7F10 Device Information, 7F is battery level = 31 which means battery is 100%, we measure battery level from 0-31, which means 0-100%. Version is 0x10, which means Rejeee temp/humi sensor. 033C and 033A is temperature, is 0x033C = 828 = 82.8, 0x033A = 826 =82.6. is only for US market, for other market sensor will send by default. The first temp is from built-in sensor, and the second one is from external sensor. 44 and 45 is humidity, is 0x44 = 68 = 68 %RH, is 0x45 = 69 = 69 %RH. The first humi is from built-in sensor and the second one is from external sensor.
5. Local Configuration:
Note: Factory reset data uploading is every 10 mins, customers can change data uploading frequency as below: Connect sensor with a USB-C cable to computer for local configuration, through local configuration, you can change the packet frequency.
