    • RE: RS485/RS232/Serial transport class for mysensors.org

      @LeoDesigner My 1.5.2 RS485 Humidity sensor send the same messages as the example Humidity sketch, but shows a lot of 'X' and '?' characters at 115200 in Serial Console.

      The console with the example Humidity sketch is clean:

      sensor started, id=1, parent=0, distance=1
      send: 1-1-0-0 s=255,c=3,t=11,pt=0,l=8,sg=0,st=ok:Humidity
      send: 1-1-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
      send: 1-1-0-0 s=0,c=0,t=7,pt=0,l=0,sg=0,st=ok:
      send: 1-1-0-0 s=1,c=0,t=6,pt=0,l=0,sg=0,st=ok:
      send: 1-1-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=ok:26.0
      T: 26.00
      send: 1-1-0-0 s=0,c=1,t=1,pt=7,l=5,sg=0,st=ok:44.0
      H: 44.00
      

      Do you know what can be causing it? Am I doing anything wrong, again?

      @LeoDesigner I still could not make it work in 1.5.2 with your library, but I will keep trying. Thanks!

      @hek I finally could make a gateway / sensor (Humidity) connection via RS485 using the development branch. Is any Controller compatible with the development branch? Thanks!

      @LeoDesigner
      Thanks for the help. I made the changes you pointed out, but still no lucky. What controller are you using? This should work in a direct crossover connection too?

    • RE: RS485/RS232/Serial transport class for mysensors.org

      @LeoDesigner
      I'm trying a Gateway & 4 relays/4 switches configuration using 1.5.2 version. As @Michal my configuration works fine with this example: https://arduino-info.wikispaces.com/SoftwareSerialRS485Example

      Anything wrong with my sketches?

      Gateway:

      /**
       * The MySensors Arduino library handles the wireless radio link and protocol
       * between your home built sensors/actuators and HA controller of choice.
       * The sensors forms a self healing radio network with optional repeaters. Each
       * repeater and gateway builds a routing tables in EEPROM which keeps track of the
       * network topology allowing messages to be routed to nodes.

       *******************************
       *
       * DESCRIPTION
       * The ArduinoGateway prints data received from sensors on the serial link. 
       * The gateway accepts input on seral which will be sent out on radio network.
       *
       * The GW code is designed for Arduino Nano 328p / 16MHz
       *
       * Wire connections (OPTIONAL):
       * - Inclusion button should be connected between digital pin 3 and GND  
       * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
       *
       * LEDs (OPTIONAL):
       * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
       * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
       * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
       * - ERR (red) - fast blink on error during transmission error or recieve crc error

        State change detection (edge detection)
      
       Often, you don't need to know the state of a digital input all the time,
       but you just need to know when the input changes from one state to another.
       For example, you want to know when a button goes from OFF to ON.  This is called
       state change detection, or edge detection.
      
       This example shows how to detect when a button or button changes from off to on
       and on to off.
      
       The circuit:
       * pushbutton attached to pin 2 from +5V
       * 10K resistor attached to pin 2 from ground
       * LED attached from pin 13 to ground (or use the built-in LED on
         most Arduino boards)
