221
222
223 The S31-NB is equipped with a NB-IoT module, the pre-loaded firmware in S31-NB will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by S31-NB.

387 == 2.3 Test Uplink and Change Update Interval ==
388
389
390 By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
391
392 User can use below commands to change the (% style="color:blue" %)**uplink interval**.
393
394 (% style="color:#037691" %)**AT+TDC=600 ** (%%) ~/~/ Set Update Interval to 600s
395
396 User can also push the button for more than 1 seconds to activate an uplink.
397
398
399 == 2.4 Multi-Samplings and One uplink ==
400
401
402 To save battery life, S31-NB will sample temperature & humidity data every 15 minutes and send one uplink every 2 hours. So each uplink it will include 8 stored data + 1 real-time data. They are defined by:
403
404 * (% style="color:#037691" %)**AT+TR=900**   (%%) ~/~/ The unit is seconds, and the default is to record data once every 900 seconds (15 minutes, the minimum can be set to 180 seconds)
405
406 * (% style="color:#037691" %)**AT+NOUD=8**     (%%)~/~/  The device uploads 8 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
407
408 The diagram below explains the relationship between TR, NOUD, and TDC more clearly:

413 == 2.5 Humidity and Temperature alarm function ==
414
415
416 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.
417
418
419 (% style="color:blue" %)**AT Commands:**
420
421 (% style="color:#037691" %)**AT+ SHHUM=min,max**
422
423 Example: AT+ SHHUM=50,80  ~/~/ Alarm when humidity lower than 50 or higher than 80.
424
425
426 (% style="color:#037691" %)**AT+ SHTEMP=min,max**
427
428 Example: AT+ SHTEMP=20,30  ~/~/ Alarm when temperature lower than 20 or higher than 30
429
430
431 (% style="color:red" %)**Notice:**
432
433 * To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
434
435 * 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: (% style="color:#037691" %)**AT+SHTEMP=-80,0.**
436
437 == 2.6 Trggier an uplink by external interrupt ==
438
439
440 S31-NB has an external trigger interrupt function. Users can use the PB15 pin to trigger the upload of data packets.
441
442 (% style="color:blue" %)**AT command:**
443
444 * (% style="color:#037691" %)**AT+INTMOD **(%%) ~/~/ Set the trigger interrupt mode
445
446 * (% style="color:#037691" %)**AT+INTMOD=0 **(%%) ~/~/ Disable Interrupt
447
448 * (% style="color:#037691" %)**AT+INTMOD=1 **(%%) ~/~/ Trigger by rising and falling edge
449
450 * (% style="color:#037691" %)**AT+INTMOD=2 **(%%) ~/~/ Trigger by falling edge
451
452 * (% style="color:#037691" %)**AT+INTMOD=3  **(%%) ~/~/ Trigger by rising edge
