1.网络校时

  • 案例说明
    使用sntp进行网络校时
  • main.py
import utime as time
import network
import sntp
g_connect_status = False

def on_4g_cb(args):
    global g_connect_status
    pdp = args[0]
    netwk_sta = args[1]
    if netwk_sta == 1:
        g_connect_status = True
    else:
        g_connect_status = False

def connect_network():
    global net,on_4g_cb,g_connect_status
    net = network.NetWorkClient()
    g_register_network = False
    if net._stagecode is not None and net._stagecode == 3 and net._subcode == 1:
        g_register_network = True
    else:
        g_register_network = False
    if g_register_network:
        net.on(1,on_4g_cb)
        net.connect(None)
    else:
        print('network register failed')
    while True:
        if g_connect_status:
            print('network register successed')
            break
        time.sleep_ms(20)

if __name__=='__main__':
    #先连上网
    connect_network()
    #校时
    sntp.settime()
    #获取当前时间
    t=time.localtime()
    #获取到的时间格式是 (年,月,日,时,分,秒,周日,年日)
    print("当前时间:",t)
    #按照一定格式输出时间
    #t_time="{:04d}-{:02d}-{:02d} {:02d}:{:02d}:{:02d}".format(t[0],t[1],t[2],t[3],t[4],t[5])
    #print("t_time:",t_time)
  • 日志输出
network register successed
当前时间: (2021, 11, 25, 2, 33, 36, 4, 328)

2.Class-sntp




sntp


settime

网络校时


  • sntp
  • sntp.settime()
  • 作用:网络校时
  • 返回:1成功

3.总结

 本节介绍了如何使用haas506的sntp模块,可以使用sntp进行网络校时。
