429 +On each sampling define by AT+TR ( default 900s or 15 minutes), when the value exceed the range, it will trigger an Alarm and immediately sends a uplink.
422 422  
423 -So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
424 424  
432 +AT Commands:
425 425  
426 -=== 2.5.3 Set Device Time ===
434 +**AT+ SHHUM=min,max**
427 427  
436 +Example: AT+ SHHUM=50,80 ~/~/ Alarm when humidity lower than 50 or higher than 80.
428 428  
429 -User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
430 430  
431 -Once S31x-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to S31x-LB. If S31x-LB fails to get the time from the server, S31x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
439 +**AT+ SHTEMP=min,max**
432 432  
433 -(% 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.**
441 +Example: AT+ SHTEMP=20,30 ~/~/ Alarm when temperature lower than 20 or higher than 30
434 434  
435 435  
436 -=== 2.5.4 Datalog Uplink payload (FPORT~=3) ===
444 +Notice:
437 437  
446 +* To disable Alarm, user can set min and max to same value , such as **AT+SHTEMP=0,0.**
447 +* If user only want to send only min or max, user can set the alarm to a value that device won’t reach. For example: **AT+SHTEMP=-80,0.**
438 438  
439 -The Datalog uplinks will use below payload format.
440 440  
441 -**Retrieval data payload:**
