Problem: wdt reset after "Sending initial information..." on "Bare minimum sketch"

[e1970180]

Hello!

I try to start use homie-esp8266 as its looks great for me.

Unfortunately, I have a problem. The device continuously reset even on "Bare minimum sketch" right after it connecting to Mosquitto broker and sending initial information. (If mqtt broker is shut down no reset occur, just waiting for connection)

I use Arduino 1.6.7 with libraries: ArduinoJson ver 5.13.2 Bounce2 ver 2.52.0 ESPAsyncTCP Latest commit 7e9ed22
AsyncMqttClient ver 0.8.2 ESPAsyncWebServer ver 1.2.0

Serial log with timestamp is below.

Do you have any idears what problem is and how to fix?

Best regards, Alex

Same issue here :-(

[bertmelis]

what is the exact error message? You need to give the reset cause before we can look into the issue.

However, it is most likely caused by

• faulty hardware (power?)
• outdated libraries (including Arduino framework)
• bad flashing
• ...

[sovcik]

Hi,

I'm trying to run it on NodeMCU connected+powered by USB. It is my usual configuration, so I'd rule power issues out. As for libraries - using Platofmio, so all were freshly installed from their repository according Homie deps. The only outdated part was the platform Espressif8266, which was at 1.8.0. Will try updating that one too.

For now it looks as follows:

Your upload speed looks way too high. I can not imagine, that the ESP is able to write the flash that fast.

-D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY

anything with low memory never worked for me at all.

[sovcik]

It seems to have an issue with this part:

    case AdvertisementProgress::GlobalStep::SUB_SET:
      packetId = Interface::get().getMqttClient().subscribe(_prefixMqttTopic(PSTR("/+/+/set")), 2);
      if (packetId != 0) _advertisementProgress.globalStep = AdvertisementProgress::GlobalStep::SUB_BROADCAST;
      break;

packetId == 0 after calling that subscribe method

It tries 4x and then resets...

[kleini]

Yes, because of the low memory build_flag. That build flag reduces the TCP_MSS size. This is the outgoing TCP buffer. Due to async TCP traffic, outgoing TCP packets need to be placed into the outgoing TCP buffer and when this buffer is full, the whole TCP stack dies. I encounter the same issue with high memory build flag too much MQTT topics sent in the Homie.loop() methods of HomieNodes. See #515 .

[sovcik]

Your upload speed looks way too high. I can not imagine, that the ESP is able to write the flash that fast.

It is fine for NodeMCU. Works like magic and saves my time. Using 115200 other ESP chips.

-D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY

anything with low memory never worked for me at all.

Only included this because it was recommended in this repo :-)

Anyway, tested slower upload speed & removed that build option too. Same result.

[kleini]

The whole async TCP stack works completely different compared to what is expected on normal operating systems as this is a microcontroller. This requires proper handling of TCP data down into the application code, as the interstratified frameworks (Homie, AsyncMQTT, ESPAsyncTCP, AsyncTCP) do not introduce additional buffers and just give failed returns codes. Those failures then need to be handling in the application code, which is very hard for unexperienced coders.

[kleini]

Use

-D PIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH

[sovcik]

With that PIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH got one step forward, up to

  case AdvertisementProgress::GlobalStep::SUB_BROADCAST:

Then it resets :-(
