Introduction:
The internal test service of TZ-IOT has been launched in "The Internet of Things Platform TZ-IOT Releases Transparent Cloud Internal Test Service: V1.0 ", and the Python SDK is released in this article.
use:
You don't need to rent a public server, you can choose an embedded device like a networkable PC or Raspberry Pi to be a server. Communicate with nodes that are also based on TZ-IOT.
installation:
pip install tziotaIf it is already installed, you need to update the latest version:
pip install tziota --upgradeinitialization:
First , apply for the IA address of the node according to the instructions in the " Internet of Things Platform TZ-IOT Releases Transparent Cloud Internal Test Service: V1.0 ".
Suppose you apply for the address: 2140:0000:0000:0101 (abbreviated 2140::101), and the password is "456".
The initialization code:
def main():
# 初始化参数
param = tziota.Param()
# 本地UDP绑定的IP和端口
param.local_ip = "10.58.4.52"
param.local_port = 14131
# 本节点IA地址和密码
param.local_ia = 0x2140000000000101
param.pwd = "456"
# 服务器IP和端口
param.server_ip = "115.28.86.171"
param.server_port = 14129
# 服务器IA地址
param.server_ia = 0x2140000000000002
tziota.init(param)
# 注册接收回调函数
tziota.register_callback_rx(deal_rx)Receiving interface:
In the callback function:
def deal_rx(ia, data):
print('IA:0x%016x' % ia)
for x in data:
print('%02x' % x, end=' ')
print()ia: IA address of the other party
data: data sent by the other party
Send interface:
frame = bytearray()
for i in range(5):
frame.append(i + 10)
tziota.send(0x2140000000000100, frame)The send interface has two parameters:
The first is the destination IA address, and the second is the data to be sent.
Online interface:
tziota.is_online():Online refers to whether the node is successfully connected to the server.
