This mode allows the user to configure the registers of the product.
To enter in this mode, plug the micro-USB cable and use the IoT Configurator or AT command. Exit from command mode is done when USB

PARK or PRODUCTION.
2.1.3 PRODUCTION mode
This mode allows the user to operate the product in its finale use.
2.1.4 Low battery management
When the product detect that the battery is not able to deliver the level of power required for a emission (extreme temperature or end-of-life of

battery” flag in the status byte of each frame sent.
The “battery low” flag is automatically disappearing when the battery is replaced or when temperature conditions are favorable to the proper
functioning of the battery.
