The Downlink information displayed on the device relates to a Downlink frame sent from a LoRaWAN network. If no information can be found
in this section, this does not indicate that the device will not function on the network but only that it has not received any information from the
network. To validate the upload link (sending a frame from the device to the network) it is necessary to use an interface that will allow you to read
frames from the network (example: back-end or application).
The device can either be configured in CONFIRMED mode or UNCONFIRMED MODE (see paragraph 5.4) In CONFIRMED mode, the confirmation
frame allows you to obtain Downlink information. In UNCONFIRMED mode, this information will not automatically be displayed.
