"Early" crashes with H801

luebbe commented 6 years ago

Hi Folks,

I'm trying to get a H801 up and running with Homie. Using the follwing minimal firmware with current homie developer branch, Homie usually crashes once or twice within the first 20 seconds after a reboot.

#define FW_NAME "homie-minimal"
#define FW_VERSION "1.0.0"

#include <Homie.h>

#define RED_LED_PIN 5

void setup() {
  Homie_setFirmware(FW_NAME, FW_VERSION);

  // H801 is using Serial1
  Serial1.begin(SERIAL_SPEED);
  Homie.setLoggingPrinter(&Serial1);

  Homie.getLogger()
      << endl
      << endl
      << "Device: " << WiFi.hostname() << endl
      << "ChipID: " << ESP.getChipId() << endl
      << "Last reset reason: " << ESP.getResetReason() << endl
      << "Memory size: " << ESP.getFlashChipSize() << " bytes" << endl
      << "Free heap: " << ESP.getFreeHeap() << " bytes" << endl;

  // The green LED on the board is connected to Pin 1, which is also the serial port
  // So we use the red LED for feedback
  Homie.setLedPin(RED_LED_PIN, LOW);
  // Homie.disableLedFeedback();
  Homie.disableResetTrigger();

  Homie.setup();
}

void loop() {
  Homie.loop();
}

Once the firmware "survives" the first 60 seconds, it runs stable from then on. I think it must be an initialization problem, but I have no idea how to track it down.

The typical log output looks like this:

my platformio.ini:

[platformio]
env_default = esp01_1m

[common]
serial_speed= 74880
lib_deps =
  https://github.com/marvinroger/homie-esp8266.git

[env:esp01_1m]
platform = espressif8266
board = esp01_1m
framework = arduino
lib_deps = ${common.lib_deps}
build_flags = -Wl,-Tesp8266.flash.1m64.ld -D SERIAL_SPEED=${common.serial_speed}
upload_speed = 230400
monitor_baud = ${common.serial_speed}
monitor_rts = 0
monitor_dtr = 0

This doesn't happen with the same sketch on a D1 mini or an ESP12F. The only difference is serial vs. serial1 and that I call 'Homie.disableLedFeedback()' on the other devices.

Any pointers are greatly appreciated. I can try to backtrack if this doesn't happen with older revisions of Homie.

And now something weird. When I change loop to print a dot every second, the firmware doesn't crash. (At least it didn't in ten tries). When I comment the "dotty" part out, it crashes again at least once within 20 seconds.

void loop()
{
  Homie.loop();
  unsigned long ms = millis();
  if (ms - lastdot >= 1000UL || lastdot == 0)
  {
    Homie.getLogger() << ".";
    lastdot = ms;
  }
}

OK, now it crashed once in 20 tries, but without the dots it crashes every time.
