WTS Temperature sensor
12 / 32
2.4 Uplink Payload
The uplink payload includes totally 11 bytes. Uplink packets use FPORT=2 and every 20 minutes
send one uplink by default.
After each uplink of WTS-10 and WTS-11, the blue LED will flash once
If the PT100 is not connected, the red LED will flash once every time the WTS-11 uplinks
Normal Uplink Payload. Total 11 Bytes.

Value In Place
0: Device in place

Battery Voltage example:
0x0BA4=2980mV
Notice:
In Place detection and light status both are interrupt event, device from in-place to out-of-place
or light from dark to bright will cause an uplink packet.

 None-ACK Flag:
 0: If this uplink payload is a new sampling payload, this flag is set to 0.
 1: If this uplink is an old uplink payload which generated while there is none-LoRaWAN
coverage, this flag is set to 1.
 Sync time OK: 1: Set time ok，0: N/A. After time SYNC request is send, device will set this bit to 0
until got the time stamp from application server.
 Unix Time Request:1: Request server downlink Unix time, 0 : N/A. In this mode, WTS will set this
bit to 1 every 10 days to request a time SYNC. (AT+SYNCMOD to set this)
 Model:
 0x01: WTS-10
 0x02: WTS-11
 0x03: WTS-12
