NRF5 Hardware module crash after while



  • Re: nRF5 action!

    I have build up a few NRF modules, including main supply power, Relais, Heating control by pilot wire, all to fit within a 2 DIN unit module within power panel.

    They all suffer the same issue, after some time could be few hours or even more than a day they do crash on trying sending something

    I have spent nearly a month reading left and right about this in mysensor but did not find ant thread on such issue. I have also tryed either the lastes stable or the dev release without any change. This is propably something evident I dont figure out and thick you help !๐Ÿ˜€

    I did attach part of the code and part of the debug output when failing

    /*
     * This example sketch shows how you can manage the nRF5 pin mapping as part of your code.
     * You can use the method for any nRF51822 or nRF52832 board or module.
     * 
     * Most components, like UART, SPI, Wire Bus, of the nRF5 series chips don't
     * have a fixed pin mapping. There are some pins with restrictions like analog
     * inputs, NFC or pins near the radio module. Please refer the latest
     * documentation about pin restrictions at http://infocenter.nordicsemi.com 
     * 
     * To use the custom pin mapping you have to do following steps:
     * 
     * 1. Install "arduino-nrf5" like described at
     *    https://github.com/sandeepmistry/arduino-nRF5/
     * 2. Install the "My Sensors nRF5 Boards" with the board manager like
     *    explained at https://github.com/mysensors/ArduinoBoards
     * 3. Copy the files "MyBoardNRF5.cpp" and "MyBoardNRF5.h" from
     *    "MyBoardNRF5" example into your sketch.
     * 4. Modify pin mappings in "MyBoardNRF5.cpp" and "MyBoardNRF5.h" to fit
     *    your requirements.
     * 5. Select "MyBoardNRF5 nrf52832" or "MyBoardNRF5 nrf52822" as your board.
     *    Choose the correct parameters and programmer in the Tools menu.

  • @Didou, if I understand it well, you have a few NRF modules build.
    Each module consist of one NRF5 board, relais, pilot connections for heating control and powered by a onboard 220V AC convertor module. All this packed together in a 2 DIN unit module inside your house power panel = electrical cabinet of your house?

    If my understanding is correct, the first thing I think of, is electrical influence of the high AC voltages inside your electrical cabinet. Don't know where you live, but are we speaking of 220/250V or 380V?
    Low voltage applications powered by 5V or 3.3V do not like noisy environments like a electrical cabinet.

    How long are the pilot wires to your heaters? Long wires act as antennas...
    Did you try to operate them outside your electrical cabinet on a test basis?



  • @Didou There is currently a bug in the NRF5 transport layer that causes them to lock up. It seems more likely to happen when the connection between the gateway/repeater is weak or too far.

    You can read more about it here: https://forum.mysensors.org/post/108301.

    My understanding there is a fix pending review and @waspie has been testing it with some NRF51822 modules.



  • @ncollins
    Seems to be working well on NRF51, not so much on NRF52. I backed off the changes for NRF52 modules and they're working ok with latest alpha. I think I need a better sketch for them...

    Anyway, NRF51822 is doing much much better.

    @Didou follow the links posted by @ncollins

    The first big dip on 11/29 was a deadlock. I tried some change after that that still didn't work and lead to another deadlock on 12/7. Using the fix from github you can see how much more stable battery reporting has been since 12/9 (small spike when it was plugged in for programming) when i flashed it using the fixed code. This one might finally be fixed.

    8a34ba1c-f51f-4806-95d1-349e382491df-image.png



  • @waspie @ncollins Thanks for feedback, when trying the fix are you taking the full github dev or only the proposed fix for this issue ? To manage the deadloack are you using the watchdog ?



  • @ncollins Will try that just have to understand how to just add the fix to the latest stable release



  • @evb You do undertstand it very well, it was also my first understanding and to avoid any issue relating to EMC I did also tried outside the cabinet, not using my own power supply adding extra capacitors and lately power up the CPU module with the NFC on batteries .... In all cases the crash issue is still there !

    I was pretty surprises as there is quiet a lot of different modules been built on openhardwareio and I have seen no report about this issue, so i was conviced the issue was mine !



  • @Didou let's then keep our fingers crossed that it's just a software problem ๐Ÿ™‚



  • @Didou @evb
    I download the dev version AND replaced the two files with the ones from the proposed fix.

    I think that's the right path - it seems to be showing positive results.



  • @Didou for my testing, I pulled the entire branch referenced in the merge request. I believe that is MySensors-development + nrf_esb_redesign changes. But you're probably safe to just replace the two files touched in the commits.



  • @ncollins OK thanks, I did try that pulling diretly from github, so branch + files (Alpha-1)

    I did upgrade 3 modules and keep many others with previous to have a comparison basis

    Let's cross fingers ๐Ÿ™‚

    It is about 12 hours for now, none of the updated one did crash and one for the unpatched did crash. I need to wait at lest 24 to 36 hours to confirm



  • @Didou Which NRF5 module are you using exactly?

    I also believe this code from your sketch is unnecessary, given MySensors handles most of it:

    void nRF_Init() {
      NRF_POWER->DCDCEN = 0; // Not reducing the radio current   
      NRF_PWM0  ->ENABLE = 0;
      NRF_PWM1  ->ENABLE = 0;
      NRF_PWM2  ->ENABLE = 0;
      NRF_TWIM1 ->ENABLE = 0;
      NRF_TWIS1 ->ENABLE = 0;
      //NRF_RADIO->TXPOWER = 8;
    }
    
    void disableNfc() {
      NRF_NFCT->TASKS_DISABLE = 1;
      NRF_NVMC->CONFIG = 1;
      NRF_UICR->NFCPINS = 0;
      NRF_NVMC->CONFIG = 0;
    }
    
    void turnOffAdc() {
      if (NRF_SAADC->ENABLE) {
        NRF_SAADC->TASKS_STOP = 1;
        while (NRF_SAADC->EVENTS_STOPPED) {}
        NRF_SAADC->ENABLE = 0;
        while (NRF_SAADC->ENABLE) {}
      }
    }
    


  • @ncollins I'm using NRF52832 Ebyte modules
