21 == 1.1 What is LoRaWAN Soil pH Sensor ==
22
23
24 The Dragino SPH01-LB/LS is a (% style="color:blue" %)**LoRaWAN Soil pH Sensor**(%%) for IoT of Agriculture. It is designed to measure the soil PH and soil temperature, so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.
25
26 SPH01-LB/LS probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect(% style="color:blue" %) **soil's pH **(%%)with high accuracy and stable value. The SPH01-LB/LS probe can be buried into soil for long time use.
27
28 The LoRa wireless technology used in SPH01-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
29
30 SPH01-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
31
32 SPH01-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery **(%%)or (% style="color:blue" %)**solar powered + li-on battery**(%%) it is designed for long term use up to 5 years.
33
34 Each SPH01-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

172
173
174 The SPH01-LB/LS is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the SPH01-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

389 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
390
391
392 === 2.5.3 Set Device Time ===
393
394
395 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
396
397 Once SPH01-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to SPH01-LB/LS. If SPH01-LB/LS fails to get the time from the server, SPH01-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
398
399 (% style="color:red" %)**Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
