As a professional module manufacturer, MOKOSmart enables you to visit LoRaWAN network and extend specific functions through AT commands.

AT Module

PEX interface for LoRa antenna
24mm x 19mm*2.8mm

Functions such as data upload and environmental monitoring are required by some IoT projects. Such requirements seems easy as it can be realized by writing the module driver interface and communication logic on apps as long as the API inteface is provided. However,if we are making another new projects with the similar functions,we still need to run through different driver procedures,which makes it seems troublesome. The AT module is based on such problems and can be divided into 3 modes as below:
• AP mode
• STA mode
•  AP+STA mode

Taking STA mode as an example, to connect with the cloud server at last, we need to complete the initialization process first, and send the following instructions:
AT+RESTORE\r\n: Module reset
ATE0\r\n: Echo off
AT+CWMODE=1\r\n: Setting up multiple connection
AT+CIPMODE=0\r\n: Disable transparent transmission mode
AT+CIPMUX=1\r\n: Start multi-connection mode
AT+CWJAP=”TOS”,”12345678″\r\n: Hot link

After initialization is completed, you can enter the data transmission, connect the server, and then open the transparent mode, into the transparent mode, and then you can send the data directly to the background, at this time you can also read the background message. When we do not need the module, we can also power off the module. Therefore, we can frame the driver process on this basis, that is, we have interfaces to initialize, connect to the server, send, receive, close and so on.
