Using Multiple Sensors On Single Websocket Connection

To use multiple sensors over single websocket connection use following URL.

         ws://<ip>:<port>/sensors/connect?types=["<type1>","<type2>","<type3>"...]

By connecting using above URL you will receive JSON response containing sensor data along with a type of sensor

{
 "accuracy": 2,
 "timestamp": 3925657519043709,
 "values": [0.31892395,-0.97802734,10.049896]
 "type" : "sensor type here"
}

Python Example

import websocket
import json


def on_message(ws, message):
    values = json.loads(message)['values']
    type = json.loads(message)['type']
    print("type = ", type)
    print("values = ",values)

def on_error(ws, error):
    print("error occurred")
    print(error)

def on_close(ws, close_code, reason):
    print("connection close")
    print("close code : ", close_code)
    print("reason : ", reason  )

def on_open(ws):
    print("connected")
    

def connect(url):
    ws = websocket.WebSocketApp(url,
                              on_open=on_open,
                              on_message=on_message,
                              on_error=on_error,
                              on_close=on_close)

    ws.run_forever()
 

connect('ws://192.168.0.101:8080/sensors/connect?types=["android.sensor.accelerometer","android.sensor.gyroscope","android.sensor.light","android.sensor.magnetic_field"]')
