(FF0D & 8000:Judge whether the highest bit is 1, when the highest bit is 1, it is negative)

Humidity:

  • Humidity:    0x02A8/10=68.0%

2.4.3  Uplink FPORT=3, Datalog sensor value

PB01 stores sensor value and user can retrieve these history value via downlink command. The Datalog sensor value are sent via FPORT=3.

image-20240510144912-1.png 

  • Each data entry is 11 bytes, to save airtime and battery, PB01 will send max bytes according to the current DR and Frequency bands. 

For example, in US915 band, the max payload for different DR is:

  1. DR0: max is 11 bytes so one entry of data
  2. DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
  3. DR2: total payload includes 11 entries of data
  4. DR3: total payload includes 22 entries of data.

Notice: PB01 will save 178 set of history data, If device doesn't have any data in the polling time. Device will uplink 11 bytes of 0.

See more info about the Datalog feature.

  

2.4.4  Decoder in TTN V3

In LoRaWAN protocol, the uplink payload is HEX format, user need to add a payload formatter/decoder in LoRaWAN Server to get human friendly string.

In TTN , add formatter as below:

2.6  Datalog Feature

When user want to retrieve sensor value, he can send a poll command from the IoT platform to ask sensor to send value in the required time slot.

2.6.1  Unix TimeStamp

Unix TimeStamp shows the sampling time of uplink payload. format base on

image-20220523001219-11.png

User can get this time from link:  https://www.epochconverter.com/ :

For example: if the Unix Timestamp we got is hex 0x60137afd, we can convert it to Decimal: 1611889405. and then convert to the time: 2021 – Jan -- 29 Friday 03:03:25 (GMT)

1655782409139-256.png

2.6.2  Poll sensor value

User can poll sensor value based on timestamps from the server. Below is the downlink command.

Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.

For example, downlink command image-20220621113526-13.png  

Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00's data

Uplink Internal =5s,means PB01 will send one packet every 5s. range 5~255s.
