H2R:
There is no response because the microcontroller resets and the mailbox is re-initialized. For example, you
can use this command to force the microcontroller to restart in order to perform a new join procedure to the
network after changing the LoRajoinmode. Once the command has been received, the module temporarily
saves the current date/time and consumption, resets and restores the previously saved values.
