11.1 Firmware Contents

The sample application installed to the MVI69E-LDM contains files that are included in
the MVI69E-LDM-MQTT zip file. The contents of the zip file were copied to the Windows
10 PC's C:\Workspace folder in Chapter 2.
Although they are installed on the module with the module webpage's Firmware
Download process, the files can be FTP'd independently as well.
When the module is rebooted after the upgrade, the sample application starts via script:
/etc/init.d/S88-mqtt.
If the module has other custom files and/or the firmware update is not desirable, then the
following files from C:\Workspace can be installed over FTP connection to the module:

11.2 Run the Application

After the installation and configuration are complete, the application can be started either
automatically after device reboot (if the script /etc/init.d/S88-mqtt was installed), or it
can be started manually via telnet terminal by navigating to the folder /spft/sample/mqtt
and running the command ./mqtt-ldm-sample-app-mvi69e.
