5 COMMUNICATION PROTOCOL
This part describes the Smart-MS0101 data exchange protocol with LoRaWAN™ network.
Smart-MS0101 uses the LoRaWAN™ port 2 for uplink and downlink messages. In fields consisting
of several bytes, the little endian byte order is used.
SMART-MS0101 TRANSMITS THE FOLLOWING TYPES OF PACKETS
1. Packet with current readings, sent regularly, and every time alarm event occurs.
Size in bytes Field description Data type
1 byte Packet type (1 – for that packet) uint8
1 byte
Battery charge, % uint8
1 byte Values of basic settings
(byte field)
uint8
2 bytes Temperature in
⁰
С, multiplied by 10 int16_t
1 byte Sending reason (0 – by the time, 1 – alarm) uint8
1 byte reserve uint8
