Example of Transparent Transmission Data Interaction
Introduction
Transparent transmission data can be used in practical scenarios where there is no need for Developer Center to parse the data. Once the device has successfully connected to Developer center, call Qth.sendTrans() to enable interaction between the device and Developer Center, allowing for transparent transmission of any type of data. This section explains how to send and receive transparent transmission data in QuecPython solution.

Transparent Transmission Data Interaction
Example 1 (Send transparent transmission data)
The device calls Qth.sendTrans() to send transparent transmission data. For example, the device can call this function to send a 12-byte string "ABCabc123456" with QoS set to 1.
Sample code:
python
Qth.sendTrans(1,"ABCabc123456")Example 2 (Read transparent transmission data issued by Developer Center)
1) Developer Center issues transparent transmission data
Open the "Device Details" page, click "Device Debug" to send or receive transparent transmission data.
2) The device receives the transparent transmission data issued by Developer Center
After receiving the data, the device will pass the event in the event callback function recvTransCb(). Then you can respond to and handle the event.
python
def App_cmdRecvTransCb(value):
print('recvTrans:', value)
