With ESP32 OTA updates fails on this library

[Polderdijk]

Hi,

Thanks for this project! It runs very smooth!

Only one thing I noticed is that I can't use OTA updates when including this library.

The problem is in the __timerISR but have no clue to solve this issue.

I use the standard Arduino OTA script:

esp_task_wdt_deinit(); noInterrupts(); HTTPUpload& upload = server.upload(); if (upload.status == UPLOAD_FILE_START) { Serial.printf("Update: %s\n", upload.filename.c_str()); -- the script will crash here

The debug info:

Thanks for the report, Can you provide me with your full code including the steps how to reproduce? Thanks!

[jpraus]

Hi, I am not sure at the moment, I believe there was successful usage of the OT shield on the ESP32 but I don't remember if I done that as well. I have the board home so I will check that soon. Feel free to add support :)

    void setup() override {
        // This will be called once to set up the component
        // think of it as the setup() call in Arduino

Can I help in some way?

[halecivo]

In the end, I came across this following ESPHome config https://github.com/piio/esphome-opentherm, mentioning compatibility with JPraus's shield and it seems work fine (although it uses different opentherm library).

[jpraus]

That is great! Thank you for letting me know!

[bvweerd]

You will have to disable the timer interrupt when starting the OTA, like this:

void ICACHE_FLASH_ATTR hw_timer_disable(void) {
  timer1_disable();
}

ArduinoOTA.onStart([]() {
  Serial.println("Start");
  hw_timer_disable();
});
