TTN (物联网)计数器与Pycom Lopy4问题

Question

我在TTN的柜台上出了问题。在我将machine.deepsleep函数添加到LoPy4中之后，就发生了这个问题。我使用了nvram_save ()和nvram_restore ()函数，但是TTN中的计数器仍然没有增加。这个screenCapture：

那么，这个案子有什么问题？

这是我的代码：

enter code here

import ads1x15 as extADC
import gc
import pycom
import socket
from network import LoRa
from uModBus.serial import Serial
from network import LoRa
import machine
import ubinascii
import utime
from machine import RTC, I2C
from machine import Pin


pycom.heartbeat(False)
rtc = RTC()
i2c = I2C(0, I2C.MASTER, pins=('P3', 'P4'), baudrate=100000)
adc = extADC.ADS1115(i2c, gain=1)
pinTrig = Pin('P23', mode=Pin.OUT)

# LoRa Socket Connection with two condition

if machine.reset_cause() == machine.DEEPSLEEP_RESET:
      pinTrig.value(1)  # enable High (12v)
      print("WOKE UP FROM DEEPSLEEP 3 MINUTES !")
      utime.sleep(1)
      lora = LoRa(mode=LoRa.LORAWAN, region=LoRa.AS923)

      lora.nvram_restore() # Nvram restore function

      s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)
      s.setsockopt(socket.SOL_LORA, socket.SO_DR, 5)
      s.setblocking(False)
      s.bind(1)
else:
      pinTrig.value(1)
      utime.sleep(1)
      print("I'M PowerOn by Humans or Hard reset !")
      lora = LoRa(mode=LoRa.LORAWAN, region=LoRa.AS923)

      lora.nvram_restore() # Nvram restore function

      app_eui = ubinascii.unhexlify('********************')
      app_key = ubinascii.unhexlify('-----------------------------')
      lora.join(activation=LoRa.OTAA, auth=(app_eui, app_key), timeout=0)
      while not lora.has_joined():
            utime.sleep(2.5)
            print('Not yet joined...')

      print('Joined')
      s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)
      s.setsockopt(socket.SOL_LORA, socket.SO_DR, 5)
      s.setblocking(True)
      s.bind(1)

      def read_data_Sensor () :


      ### End sensor reading and sending function ####################


      try:
          read_data_Sensor()

          lora.nvram_save() 

          utime.sleep(1)
          pinTrig.value(0)
          print("DeepSleep Mode")
          utime.sleep(1)

          machine.deepsleep(180000)
      except OSError:
          print("Terjadi Error - Restart")
          s.send(b"\xff\xff")
          utime.sleep(1)
          machine.reset()

我对nvmram_save/restore方法的理解是，它们恢复lora堆栈的全部状态，包括“连接/不连接”状态。如果每次都显式执行join()，那么这两者都会在联接交换中浪费精力/时间，此过程将始终将计数器重置为0。

我认为您的代码应该在lora.has_joined()之后测试nvram_restore()，并且只有当返回False时才执行联接过程。

顺便说一句，我还遇到了TTN v3中的pycom和nvmram_save/还原问题。
