LoRaWAN, MODBUS and MQTT DETAILS
LoRaWAN DETAILS
Status Message - Device Status
Message sent to LoRaWAN Port number 1 in every connection to LoRaWAN Server
4 Bytes: HUR Device Id
1 Byte: Frame Type (Lower 4 bits) and Package Number (Upper 4 bits). If Package Number is 1 or more that means the package splitted.
0x00 : means status package for device status and package is the first package
1 Byte: Number of I/O Slots available in HUR device
1 Byte for each Slot (4 bytes for 4 Slots): Slot Types available in HUR device
Available Options: 'HUR_8_DIGITAL_IN', 'HUR_8_DIGITAL_OUT', 'HUR_8_ANALOG_IN', 'HUR_5_ANALOG_OUT'
1 Byte: LoRaWAN target port for I/O data
4 Bytes: RTC Time
3 Bytes: HUR Device firmware version
N Bytes (maximum 22): LKM Device name configured by user


I/O Data Message

Message sent to LoRaWAN configured port and minimum send interval can be configured by user

4 Bytes: HUR Device Id
1 Byte: Frame Type (Lower 4 bits) and Package Number (Upper 4 bits). If Package Number is 1 or more that means the package splitted.
0x02 : means meter data package and package is the first package
4 Bytes: RTC Time
1 Byte: Number of I/O Slot which the data is shared
1 Byte: Type of I/O Slot which the data is shared
1 Byte: Total number of bytes in Payload
