Install rust if you don't have it already, find the instructions here https://www.rust-lang.org/tools/install
Make sure you also have the build dependencies installed, if not run:
sudo apt install build-essential
sudo apt install pkg-config
sudo apt install libssl-dev
sudo apt update
Download the Repository:
git clone https://github.com/iot2tangle/Streams-wifi-gateway.git
Configure the streams-gateway:
nano config.json
Set the device_name to the value specified in the configuration file of the XDK110.
Change port, node, mwm, local_pow if needed
Run the streams-gateway:
cargo run --release
This starts the server which will forward messages from the devices to the Tangle
The Output will be something like this:
>> Starting....
>> Channel root: "ab3de895ec41c88bd917e8a47d54f76d52794d61ff4c4eb3569c31f619ee623d0000000000000000"
>> To Start the Subscriber run:
>> cargo run --release --example subscriber "ab3de895ec41c88bd917e8a47d54f76d52794d61ff4c4eb3569c31f619ee623d0000000000000000"
>> Listening on http://0.0.0.0:8080
In a separate window start a subscriber using the Channle Root printed by the Gateway (see example above):
cargo run --release --example subscriber <your_channel_root>
To send data to the server you can use Postman, or like in this case cURL, make sure the port is the same as in the config.json file:
curl --location --request POST '127.0.0.1:8080/sensor_data' --header 'Content-Type: application/json' --data-raw '{ "iot2tangle": [ { "sensor": "Gyroscope", "data": [ { "x": "4514" }, { "y": "244" }, { "z": "-1830" } ] }, { "sensor": "Acoustic", "data": [ { "mp": "1" } ] } ], "device": "XDK_HTTP", "timestamp": "" }'
Note: Thetimestamp will be set the moment the transaction is sent to the Tangle
IMPORTANT: The device will be authenticated through the "device" field in the request (in this example XDK_HTTP), this has to match what was set as device_name in the config.json on the Gateway (see Configuration section above)!
