CONVERTER M-BUS-2 RECEIVES PACKETS OF THE FOLLOWING TYPES
1. Real-time clock adjustment – send by application on LoRaWAN port 4
Size in bytes Field description Data type
1 byte Packet type, this packet = 255 uint8
8 bytes The value in seconds for which you need to adjust the time.
Can be positive or negative int64
2. Packet with request of settings – sent by application on LoRaWAN port 3
Size in bytes Field description Data type
1 byte Packet type, this packet == 1 uint8
Answering that packet, the device sends the packet with settings.
3. Packet with settings is identical to such packet from device
Size in bytes Field description Data type
1 byte Packet type, this packet == 00 uint8
2 bytes ID of parameter uint16
1 byte Data length (len) uint8
len bytes Parameter value -----
2 bytes ID of parameter uint16

The package with settings sent to the device may not contain all the settings supported
by the device, but only the part that needs to be changed.
