3.2.3. Httpd Client Mode
In this mode, users’ serial device can send request data to indicated HTTP server. Then DTU receive data
from HTTP server, analysis data and send the resault to serial device.
No need to pay attention to the data conversion process between serial data and network data packet,
users can realize data request from serial device to HTTP server.
