LoRaWAN
The LoRaWAN I/O Server implements both a LoRaWAN Network and Application servers for the integration of a LoRaWAN network.
HSYCO acts as a server for one or more LoRaWAN gateways configured as standard Semtech packet forwarders. Communication is carried on UDP packets.
The implementation complies with the Semtech's paket forwarder protocol v4.0.1 and supports Class A end devices using unconfirmed data frames and ABP authentication.
Contents
HSYCO Configuration
Add a LORAWAN I/O Server in the I/O Servers section of the Settings and set its parameters:
Note that only one instance of the LORAWAN I/O Server is allowed and it consumes one item for each defined gateway from the I/O Servers license total.
High Availability
- Shutdown when inactive: defaults to true.
Options
| ID | Default | Values | Description |
|---|---|---|---|
| localport | <port_number> | the IP port number used locally by HSYCO to listen for incoming UDP packets sent by the gateways | |
| debug | false | true | print debugging information to the logs |
| false | don't print debugging information to the logs |
LoRaWAN Utility
Use the LoRaWAN Utility to automatically discover gateways and devices and setup the communication and functional parameters.
Gateways Configuration
Configure the gateway(s) as standard Semtech packet forwarder(s). Make sure the network configuration allows for the communication with HSYCO and use HSYCO's IP address and the port number specified in the "localport" option for the network server's configuration.
