  thanks, so i have tried the following and it works but i do receive an echo of the input command. so i tried with the \x10, but this does not work, however i receive the following echoed back.

  when issuing the following command

  "beam(sleep)\n"
  

  i get

  {"topic":"/ble/data/d8:19:e7:5b:3a:57/nu­s/nus_rx","payload":"beam(sleep)\r\n","q­os":0,"retain":false,"_msgid":"2846d788.­245218"}

  and

  {"topic":"/ble/data/d8:19:e7:5b:3a:57/nu­s/nus_rx","payload":"=\"testing\"\r\n>",­"qos":0,"retain":false,"_msgid":"3714119­6.ec66fe"}

  however when issuing the following command to rid of the echoed command

  "\x10beam(sleep)\n"
  

  i only get

  {"topic":"/ble/data/d8:19:e7:5b:3a:57/nu­s/nus_rx","payload":"\"\x10beam(sleep)\n­\"","qos":0,"retain":false,"_msgid":"721­7a5c4.d44c8c"}

  Could i use a puck.js to detect another puck presence, i.e. have one in the car and another in the garrage, and use the one in the garrage to detect the one in the car, i.e. rssi level and act when rssi level is at certain value?

  Thanks

  This my code so far on the puck , and I am able to connect using the python code below and send commands, but I am unable to return a value back, actually I do receive something, such as

  <type 'str'>
  <- Serial1
  >
  

  but it should be temperature reading of the puck. any help please

  Puck Code:

  function beam(ircode)
  {
    Puck.IR(require("pronto").decode(ircode)­);
    digitalWrite(LED2,1);
    setTimeout(function() 
    {
      digitalWrite(LED2,0);
    }, delayInMilliseconds);
    return E.getTemperature();
  }
  

  Python:

  import sys
  from bluepy.btle import UUID, Peripheral
  import time
  import binascii
  from bluepy import btle
  
  command = "\x03\x10beam(" +sys.argv[2]+ ");\n"
  
  class MyDelegate(btle.DefaultDelegate):
      def __init__(self):
          btle.DefaultDelegate.__init__(self)
  
      def handleNotification(self, cHandle, data):
          print("A notification was received: %s" %data)
          
  p = Peripheral(sys.argv[1], 'random')
  p.setDelegate(MyDelegate())
  try:
          UartService=p.getServiceByUUID(UUID("6E4­00001-B5A3-F393-E0A9-E50E24DCCA9E"))
          ch = UartService.getCharacteristics(UUID("6E4­00002-B5A3-F393-E0A9-E50E24DCCA9E"))[0]
  
          while len(command)>0:
                  ch.write(command[0:20]);
                  command = command[20:];
  
          
          p.writeCharacteristic(ch.valHandle+1, "\x02\x00")
  
          while True:
              if p.waitForNotifications(1.0):
                  # handleNotification() was called
                  continue
  
              print("Waiting...")
