Possible Bug version 2.2.0



  • Good morning, for one of my Weather Station (very early stage) I used the code below. Which works perfectly with MySensors 2.1.1
    Yesterday I updated my Arduino IDE to Version 2.2.0 and when I try to compile the code it goes, but once loaded the scketch on my arduino Pro, it does not work, while reloading the code compiled with MySensors 2.1.1 It works !!

    I think there is something wrong with the latest version of Mysensors

  • @sindrome73 it does not work is a large statement. Did you try different Arduino? Logs?


  • Contest Winner

    @sindrome73 you use signing? Have you followed the signing migration guide for 2.1 to 2.2?
    https://forum.mysensors.org/topic/7843/security-migrating-from-library-version-2-1-to-2-2



  • @anticimex Just out of curiosity - what happens if re-personalisation is not done after moving to 2.2.0? Signing fails?


  • Contest Winner

    @alexsh1 checksum verification for the signing backend will fail and signing will not operate



  • @anticimex OK, but if the GW is still on 2.1.1 and nodes are 2.2.0 it should be fine, right?


  • Contest Winner

    @alexsh1 if the 2.2 node has correct checksum yes. And this is shown in the debug log.



  • @anticimex

    532/5000
    I made the customization from the beginning, with MySensors 2.2.0

    I followed these steps:

    • The EEPROM has been deleted
    • Open SecurityPersonalize.ino inserted the new Key
    • loaded the scketch and it does not go

    I redid the same procedure above, then EEprom deleted, SecurityPersonalize file, and loaded the scketch, but this time using Mysensors 2.1.1
    And here it worked ..... The same thing I did on Several Pro Mini at 5V 16Mhz and the result is the same ..... That's why I assume there may be something wrong with 2.2.0


  • Contest Winner

    @sindrome73 2.2 works. At least signing. Log please.



  • I apologize, but I did not understand what you tell me ....

    I would like to add that the script without the signature with the 2.2 version works, while the signature works only with MySensors 2.1


  • Contest Winner

    @sindrome73 log please.



  • In the evening ..... Now I'm at work and I can not


  • Contest Winner

    @sindrome73 no problem



  • Here I am at home .... I proceeded to redo the procedure and this sot is the log ....

    I had to put an image because the last signs that mida I can not copy them as text ....

    0_1522266474450_Log_arduino.jpg


  • Contest Winner

    @sindrome73 log looks pretty corrupt, but I can't find any signing related messages so it would seem signing is not enabled on the node. Do you have a log from the GW? Is it also running 2.2.0?


  • Contest Winner

    @sindrome73 sorry, the capabilities string indicate software signing. But I don't see the backend initialization message. Could you please enable verbose signing debug?



  • tell me how to abbilitate the detailed signature debug .....


  • Contest Winner



  • Here is the log with the Debug signed abbreviation.
    I specify that I had to disable // # define MY_DEBUG because the scketch is too big

    0_1522270397919_Log_arduino2.jpg


  • Contest Winner

    @sindrome73 signing messages look sane. But the logs look very corrupt. It also looks like the sketch crashed and restarted so I suspect you are running out of stack space. The arduino IDE reports and warns about memory usage and I suspect you get a warning on that.
