The Multi-tech MTCAP gateway does have a HTTPS REST API available to access the LoRaWAN network server device whitelist (device address including device data and timestamp).

Accessing the Gateway

Does require the respective device credentials, which then gives a token.

Note: The token eventually expires.

Example: https://192.168.10.73/api/login?username=MTCAP4&password=MVA-LoRa

{
   "code" : 200,
   "result" : {
      "address" : "192.168.10.51",
      "isipcuser" : false,
      "isremoteuser" : false,
      "permission" : "admin",
      "port" : "49623",
      "timestamp" : "14:13:48:323",
      "token" : "F073732291A5C26BF912E80267780A",
      "user" : "MTCAP4"
   },
   "status" : "success"
}

Device whitelist:

View of all devices that are enabled in the gateway:

Example: https://192.168.10.73/api/loraNetwork/whitelist

{
   „code“ : 200,
   „result“ : {
      „devices“ : [
         {
            „appeui“ : „31c209e170312003“,
            „appkey“ : „f9d446b18f7af0431381af028c98998c“,
            „class“ : „A“,
            „deveui“ : „3335313568318a10“,
            „device_profile_id“ : „LW102-OTA-EU868“,
            „network_profile_id“ : „DEFAULT-CLASS-A“
         },
         {
        …
         },
      ],
      „enabled“ : true
   },
   „status“ : „success“

}

Packet’s view:

These include uplink and downlink packets.

Each packet contains the moment at which it was created (timestamp).

Each packet contains a "deveui" field; this matches the label on the back of the device.

For the uplink packets, the contents of the "data" field can be deserialized to read.

For the downlink packets, the contents of the "data" field can be deserialized to read.

Example: https://192.168.10.73/api/lora/packets
