    • RE: Door sensor make USB disconnect while reading serial output?

      Hey,

      Just for information: I solved all my problem ny soldering. Don't know if this is the breadboard or the Dupont wire jumpers, but with wires soldered, everything is working now ๐Ÿ™‚

      Your problem report also reminds me to problems other users had with their LAN-GW's. For them afaik downgrading the board definition for the nanos (not the IDE) to version <=1.6.11 helped a lot. You might give that a try...

      Ok, I don't really understand yet what is the board definition version, but I will try. Thank you ๐Ÿ™‚

    • RE: Door sensor make USB disconnect while reading serial output?

      Hey there,

      How can I know which Arduino Nano are good for MySensors?
      Mine are from Banggood and the serial output seems to be chaotic.

      I have one from Gravitech and it seems to be okโ€ฆ

      How to choose? In the MySensors store, this is clone form Asia like mine from Banggoodโ€ฆ

      Did you try adding a larger capacitor on the radio?

      Yes, but still the same.

      I grab another Arduino Nano (not sure it's a guenuine one) and the serial output is correct! The sensor can not find the gateway, but this is another story ๐Ÿ™‚

      Do you know why some Arduino Nano V3 "compatible" will not work?

      Hello,

      I tried with two spares modules and I am still stuck with this curious behaviour.

    • RE: Door sensor make USB disconnect while reading serial output?

      @sundberg84 I swapped Nano between the gateway and the sensor and this bug always occurs with the sensor sketch. I have spare radio modules, so I will try with another one, thank you for this suggestion ๐Ÿ˜‰

      I use the 3v3 output of the Arduino to power the radio module ๐Ÿ™‚

    • RE: Door sensor make USB disconnect while reading serial output?

      @sundberg84 I use Arduino Nano V3, breadboards and NRF24L01+ with a 4.7 ยตF capacitor. For debugging, a use USB port from my computer or RaspberryPI. I tried with a USB charger for cellphones, and nothing seems to change (but I am blind without serial ๐Ÿ˜„ )

      About software, I use Arduino IDE v1.8.5 and MySensors v2.1.1.

      @rejoe2 said in Door sensor make USB disconnect while reading serial output?:

      @guilou First, I can not see the serial output you tried to link, the log parser page remains blank.

      That is weird, on my computer all links are ok.

      Anyway, I tried to disconnect/reconnect the Arduino without reflashing the sketch, and I have still the same behaviour: the output stops, and at the same time the Arduino change its portโ€ฆ

      26773 TSF:MSG:SEND,10-10-255-2550 MCO:BGN:INIT NODE,CP=RNNNA--,VER=2.1.1
      41 TSM:INIT
      55 TSF:WUR:MS=0
      76 TSM:INIT:TSP OK
      97 TSM:INIT:STATID=10
      119 TSF:SID:OK,ID=10
      14
      

      The "14" on a single like lets me think the serial communication is interrupted at this exact point.

      I tried other cables and power source without any success.

    • Door sensor make USB disconnect while reading serial output?

      Hello,

      I have two Arduino Nano and I just want to build a domotic system with Home Assistant and MySensors.
      So, I build a serial gateway with one Arduino, just by copy/pasting the documentation example. By reading the debug, I think it's quite good.

      For the sensor, my code is:

      // Enable debug prints to serial monitor
      #define MY_DEBUG 
      #define MY_BAUD_RATE 9600
      
      // Enable and select radio type attached
      #define MY_RADIO_NRF24
      //#define MY_RADIO_RFM69
      
      #define MY_NODE_ID 10
      
      #include <SPI.h>
      #include <MySensors.h>
      
      #define CHILD_ID 3
      
      const int buttonPin = 3;    // the number of the pushbutton pin
      const int ledPin = 13;      // the number of the LED pin
      
      // Variables will change:
      int ledState = HIGH;         // the current state of the output pin
      int buttonState;             // the current reading from the input pin
      int lastButtonState = LOW;   // the previous reading from the input pin
      
      // the following variables are unsigned longs because the time, measured in
      // milliseconds, will quickly become a bigger number than can be stored in an int.
      unsigned long lastDebounceTime = 0;  // the last time the output pin was toggled
      unsigned long debounceDelay = 50;    // the debounce time; increase if the output flickers
      
      MyMessage msg(CHILD_ID, V_TRIPPED);
      
      void setup() {
        pinMode(buttonPin, INPUT);
        pinMode(ledPin, OUTPUT);
      
        // set initial LED state
        digitalWrite(ledPin, ledState);
      
        Serial.begin(MY_BAUD_RATE);
      }
      
      void presentation() {
        //sendSketchInfo("TestSketch",  "1.0");
        // Register binary input sensor to gw (they will be created as child devices)
        // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. 
        // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
        present(CHILD_ID, S_DOOR);  
      }
      
      void loop() {
        // read the state of the switch into a local variable:
        int reading = digitalRead(buttonPin);
      
        // check to see if you just pressed the button
        // (i.e. the input went from LOW to HIGH), and you've waited long enough
        // since the last press to ignore any noise:
      
        // If the switch changed, due to noise or pressing:
        if (reading != lastButtonState) {
          // reset the debouncing timer
          lastDebounceTime = millis();
        }
      
        if ((millis() - lastDebounceTime) > debounceDelay) {
          // whatever the reading is at, it's been there for longer than the debounce
          // delay, so take it as the actual current state:
      
          // if the button state has changed:
          if (reading != buttonState) {
            buttonState = reading;
      
            // only toggle the LED if the new button state is HIGH
            if (buttonState == HIGH) {
              //send(msg.set(buttonState == HIGH ? 1 : 0));
              
              delay(1000);
              ledState = !ledState;
              Serial.print("State = ");
              Serial.println(ledState);
              send(msg.set(ledState));
            }
          }
        }
      
        // set the LED:
        digitalWrite(ledPin, ledState);
      
        // save the reading. Next time through the loop, it'll be the lastButtonState:
        lastButtonState = reading;
      }
      

      The serial output is like this.

      But something weird happens just after this serial reading. The USB seems to be disconnected and then reconnect to another ttyUSB. So I can't read all the serial at once. I tried to lower the baud rate, as you can see, but there is still the bug.

      I tried to swap Arduino, change USB port, change USB cable and there is still this strange behaviour.
      Do you know why?
