# QC_Utility

## To run the Quick connect demo:
1. Open the config.txt and enter the details to the corresponding fields. 
    1. Serial_port: <Add the serial port here. Depending on the OS the serial port naming can be different. for example: Windows: COM14, MacOS, linux: /dev/tty.usbXX>
    2. SSID, Passphrase: <Optional. If your expresslink device is WiFi compatible then enter your SSID and Passphrase respectively, otherwise leave it blank.>
2. Run the script either by double clicking on the executable file or by entering ./Start_Quick_Connect command in the terminal.
3. Wait for the script to run the necessary steps before opening the visualizer. The visualizer can be accessed in two ways:
    1. At the end of the prerequisites the quick-connect executable will provide the option to launch the visualizer from the terminal. 
    2. A file named Click-me.html will be created in the Quick connect directory which opens the visualizer. 
4. The executable now publishes MQTT messages to the cloud which can be observed on the visualizer.  
5. After the demo messages are sent to the visualizer the executable opens an interactive serial terminal which can be used to send commands directly to the device.
