4.2. Downlinks

LoRaWAN technology is used to transmit information to the product from the network (downlink).
Class A of the LoRaWAN specification allows the product to receive information from the network by providing two listening windows after
each uplink communication.

4.2.1 Product configuration request frame

This frame makes it possible to inform the product via the network that it must re-transmit the product configuration upstream frame (0x10).

4.2.2 Network configuration request frame

This frame makes it possible to inform the product via the network that it must re-transmit the network configuration upstream frame (0x20).

4.2.3 Request frame for reading a piece of data

This frame (0x05) makes it possible to ask the product to retrieve the data of a specific label and to return its value in an alarm type frame
(0x4A). If there is an error in the request (invalid label or non-existing label) the downlink frame will be rejected by the device and no 0x4A
frame will be sent.

0x05 Maximum number of acquisitions
0x05
Description of the frame:
Byte 1: number of polls (= number of data acquisition processes on the TIC link) to be carried out to the maximum to find the corresponding
label
Bytes 2 to 11: label title in ASCII value
In the example in gray it gives:
Byte 1 = 0x0A is 10 scans.
Bytes 2 to 11 = 0x49494E53540000000000 a value in ASCCI: "IINST". The alarm therefore concerns the label IINST.
