4.2. Downlink frames

LoRaWAN technology makes it possible to transmit information to the product from the network
(downlink frame).
The class A of the LoRaWAN specification allows the product to receive information from the network
by proposing two listening windows after each uplink communication (uplink frame).
4.2.1

Product configuration request frame

This frame allows to inform the product via the network that it must resend the product configuration uplink frame
(0x10).

4.2.2

Network configuration request frame

This frame allows to inform the product via the network that it must resend the network configuration
uplink frame (0x20).

4.2.3

Frame for adding an offset to pulse counters

This frame allows to add an offset to the counter value on each channel.
0 1 to 4
Code
0x03 Offset - chan-
nel A
0x03 0x00000015
Its size is of 9 bytes.
Description of the frame :
• Bytes 1 to 4: Offset - channel A : numbers of pulses to add to current index of the meter (channel
A) (unsigned 32-bits, MSB first).
• Bytes 5 to 8: Offset - channel B : numbers of pulses to add to current index of the meter (channel
B) (unsigned 32-bits, MSB first).
In the example in grey this gives:
• Bytes 1 to 4 =0x00000015 so 21 pulses to add to channel A counter
• Bytes 5 to 4 =0x00000050 so 80 pulses to add to channel B counter
