Using loop function with MySensors-master/examples/ (2.2)



  • Hello,
    I'm using Mysensors for the very first time (2.2 version)
    I'm confused, everything is working excepted the loop function.
    Precisely,
    I'm editing RelayActuator and placed my code in loop function (it was already declared but empty) but my code is ignored.
    Both functions, loop() and setup() usually used in a sketch are ignored.

    (I do think that they are ignored because each serial feedback, like Serial.println(...) don't do anything)

    What can I do if i want to use them ?

    Thanks,
    Eric.

    Hi @eric007, welcome to the forum!

    loop and setup are supposed to work just like on non-MySensors sketches.
    Is MY_DEBUG defined? If not, are you calling Serial.begin() in setup? What Arduino model are you using? Do you get any other output on the serial monitor?
    Could you post your entire sketch?



  • Thanks for your answer,

    here the thing:
    i've 4 relays connected to an Adruino nano(328)
    MysensorSerialGatreway is doing the right job and all is working.
    But, i want to add a timeout option that switch off a relay after timeout reached.
    I want this option in case of a freeze or bug with my domoticz controller (running on a raspberry pi)
    Relay are used for watering my garden, so i prefer having a solution on my arduino for switching off relays in case of any bug.

    So, my idea is pretty simple:
    each time a relay is switched on i store the time
    (i'm doing this in receive() function)

     In the loop function i do some tests and check the timeout for each relay
    

    I wanted to know if it was working (i do think my code is correct) so i put some Serial output.

    as you can see in setup() or in loop(), there are two outputs.

    I do have the Mysensors classic outputs but mine do not produce anything.

    so have you an idea ?

    thanks a lot.

    here my code:

    @eric007 coyld you post the debug output of the node? It might give a clue. I can’t see snything wrong with the sketch, you should definitely get the ”setup ok” print.



  • here a snapshot of the Serial output (is that you wanted ?)
    One more thing
    usually, when I compile sketch without loop() or setup() function, an error is done.
    But here, i can remove loop() and setup() function and compile without any errors

    can both functions (loop and setup) be located elsewhere ? in a .h ou .cpp dependencies that used with #include Mysensors.h

    One last thing,
    I use last version of IDE Arduino , under debian computer.
    When i compile other sketch (my very firsts examples, without Mysensors) loop() and setup() have the right behavior

    thank for help,
    Eric.

  • Hi,
    One more thing: even if compilation succeed, there are always two warnings:
    0_1528661449959_warnings.png
    Warnings are (my traduction):
    WARNING : wrong .ci folder in library "Mysensors"
    WARNINR : wrong .mystools floder in library "Mysensors"
    For any sketch (using or not Mysensors) i do have this Warning, since i've installed mysensors library.

    It might be the the problem ?
    thank,
    Eric.


  • Mod

    @eric007 the debug output shows that the node is unable to find a path to the gateway. The default setting is to not enter setup or loop until communication has been established (since, for most use cases, running a node without communication isn't very useful)

    What type of gateway are you using? Could you post the debug output from it?


  • Mod

    @eric007 you can safely ignore the "Faux" folder warning. The english translation is "spurious" in case you want to search here in the forum.



  • Ok! I did not know.
    I was doing a try on my node and turned off my gateway.
    tomorrow i will do it again and with the gateway!
    i'll will send you a feedback.
    Thank you so much for your answers and your availability,

    Eric,



  • I'im using GarewaySerial and domoticz as controller.

    Eric.



  • Hi,
    it works perfectly, you were so right from the beginning.
    I took a wrong way because of the compilation success without loop() and setup() function in my sketch.
    Anyway, my project works fine and thank you again.


  • Mod

    Great work @eric007, thanks for reporting back!
