OTA firmware updating is too slow..

[yd kim]

It will be great. I also turn on debug..
It means driver itself is too fast to handle on atmega328??
If we can reduce delay when it fails,it will be great. 5 seconds is too much I guess.

@yd-kim what bootloader are you using? I have similar problems with tekkas newest bootloader, but the older one works fine for me.

@Anduril
Oh really? I did use MYSBootloaderV13pre.hex.
Can you let me know which one you use?
Thanks!

[Anduril]

yeah I tried with the V13pre.hex, but with that I had problems as you descibed. Also the serial upload didn't worked for me. So there was no reason to not use the old one wich was included in his beta of MYSController. That worked much better. Maybe you can find the old version on tekkas download site of MYSController.

@Anduril

Thank you! Will try tomorrow and update on this post!

just as an update, here the link to tekkas 'old' MySController with the old bootloader: https://forum.mysensors.org/topic/838/windows-gui-controller-for-mysensors/2

I implemented a check for firmware update message in my modified SenseBenderMicro sketch, and alternative behavior in the loop if FW update is ongoing. This doesn't solve the problem of dropped messages, but could be good to speed up the update and don't waste time on sensor updates.

void loop() {
  if (fwUpdateOngoing) {
    fwUpdateOngoing = false;
    fwUpdateOngoing = wait(OTA_WAIT_PERIOD, C_STREAM, ST_FIRMWARE_RESPONSE);
  } else {
    normalFlow();
  }
}

void normalFlow() {
  // Short delay to allow buttons to properly settle
  sleep(5);

  int buttonValue = digitalRead(BUTTON_PIN);

  measureCount ++;
  sendBattery ++;
  bool forceTransmit = false;
  transmission_occured = false;
#ifndef MY_OTA_FIRMWARE_FEATURE
  if ((measureCount == 5) && highfreq)
  {
    clock_prescale_set(clock_div_8); // Switch to 1Mhz for the reminder of the sketch, save power.
    highfreq = false;
  }
#endif

  if (measureCount > FORCE_TRANSMIT_INTERVAL) { // force a transmission
    forceTransmit = true;
    measureCount = 0;
  }

  sendTempHumidityMeasurements(forceTransmit);
  if (buttonValue != oldValue) {
     // Send in the new buttonValue
     send(msg.set(buttonValue==HIGH ? 0 : 1));
     oldValue = buttonValue;
     transmission_occured = true;
  }

#ifdef MY_OTA_FIRMWARE_FEATURE
  if (transmission_occured) {
    fwUpdateOngoing = wait(OTA_WAIT_PERIOD, C_STREAM, ST_FIRMWARE_RESPONSE);
  }
#endif

  sleep(digitalPinToInterrupt(BUTTON_PIN), CHANGE, MEASURE_INTERVAL);
}

@Mark-Swift I'm not sure I understood you right - can you explain how this applies to the bootloader?

Sorry to revive this old topic but I didn't find any other one that covered this topic.

I started implementing FOTA in all my nodes and was finding some low speeds as described on this topic. I then implemented the checks proposed by @martinhjelmare and they certainly helped :grinning: , although they are not yet perfect.

As I said I didn't other topics covering how to avoid the node from doing anything else while the FOTA is in place, not did I find any other examples on this web nor in the github mysensors examples folder.

Is this the only way to do this, or is there any other better way around since this was published?

[manutremo]

No wonder, I think I found the way... I found there is a function isFirmwareUpdateOngoing() in MyOTAFirmwareUpdate.cpp that seems to provide that functionality in a much easier way :+1:

[Mark Swift]

@manutremo please share your method so we can all benefit :)

[manutremo]

If I understood correctly, it should as simple as in loop:

if (!isFirmwareUpdateOngoing()) {
<do whatever>
}

but for the moment take it with a pinch of salt...

[Mark Swift]

If I recall I tried that, I seem to remember it only works for the sensebender board? Perhaps I'm mistaken though, it was over 1 year ago. @tekka, can you confirm?

[tekka]

@Mark-Swift Correct, this works only with "online" FOTA, i.e. with boards with separate flash/eeprom HW onboard.

[manutremo]

ok thanks for the clarification, I'm using a mini pro with a I2C memory, which is identified by the MYSController as a sensebender.
