MySensor auto node ID



  • Setup:

    • Raspberry Pi serial gateway.
    • Node on Arduino Nano. Bare minimum code.

    Problem:
    Node fails to register when neither NODE_ID or MY_NODE_ID defined. It registers fine when MY_NODE_ID defined explicitly.

    Sketch:

    #define MY_RADIO_NRF24
    #define MY_BAUD_RATE 38400
    #define MY_DEBUG
    
    #include <MySensors.h>
    #include <SPI.h>
    
    #define SENSOR_ID 1
    
    #define OPEN 1
    #define CLOSE 0
    
    MyMessage msg(SENSOR_ID, V_TRIPPED);
    
    uint8_t value = OPEN;
    
    void presentation()
    {
        present(SENSOR_ID, S_DOOR);
    }
    
    void loop()
    {
        value = value == OPEN ? CLOSE : OPEN;
        send(msg.set(value));
        sleep(10000);
    }

    What's wrong with my setup?


  • Mod

    @benya it looks to me like AUTO has been redefined from 255 to 0. Could you check if there are any redefine warnings in the compile output? Adding a Serial.println(AUTO) in before() might help to check the value as well. Or try to set the node ID to the value 255.


  • Admin

    Did you use the node for something else earlier? Like a gateway? Try clearing EEPROM to get rid of old settings.



  • @mfalkvidd I added

    #if MY_NODE_ID==255
    #error MY_NODE_ID==255
    #endif
    

    And compiler reported

    dummy_mysensor:16: error: #error MY_NODE_ID==255
     #error MY_NODE_ID==255
      ^
    exit status 1
    

    So MY_NODE_ID is 255.

    Yes, I cleared EEPROM as well.


  • Admin

    Did you use the provided clear sketch or do a clear yourself? If the latter, node that you should write 0xff to all positions.



  • You can confirm that you have Cleared the EEPROM by opening the Serial Monitor and see what happens



  • @hek That was it. Got node registered after clearing with 0xff.
    Thanks a lot! :joy:
