Description

i have 2 Esp32 nodemcu, they connect each other with esp now that send 2 thins: The first is the heartbeat that check if the connection between the 2 esp exist and show a led status. The second is the weight scale data that send it from ethernet udp to the esp32 and the esp32 send it over esp32 to the second one. the program works really well, send all the data, and says the connection is stablished, but after 2 or more days the esp32 stops working, the led keep blinking like the connection exist, but the esp32 not response, i have a switch that you can change the esp32 to habilitate the OTA and wifi AP so you can program it. but the switch don't work is like it get stucked, the worst part is i put a Watchdog but i think it didin't work, i can't see the log of the problem because if i connect to usb start working normally, i change the power supply 3 times and i have a capacitor filter, all this in 5v in VIN

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

me-no-dev commented 3 weeks ago

@Armagedon13 we have our own ESP_NOW library for Arduino. It seems you are using IDF directly. Also your sketch needs to be minimized to only what is necessary to replicate the issue. Code above is too large.

@P-R-O-C-H-Y PTAL

Armagedon13 commented 3 weeks ago

@me-no-dev ok, im gonna edit it

Armagedon13 commented 3 weeks ago

we have our own ESP_NOW library for Arduino

the one i made is wrong? and there is no way to know if they are connected each other, thats why i made the heartbeat for that reason, to get a feedback with leds. I see the ESP example, and it's new, it's not too easy to set up.

Jason2866 commented 3 weeks ago

I had sometimes hangs when using the W5500 with Interrupt. Since changed to use the W5500 without Interrupt it works fine

seansimmons74 commented 3 weeks ago

Forgive me if this is unrelated but I noticed you are seeing a ~50k drop in free bytes/min free bytes. I am also having this issue and it never seems to recover (eventually leading to the board crashing/hanging). The first drop is 50k and then the rest are much smaller but it eventually causes my ESP32 to hang/perform slowly due to the continued drop in free heap. I am making http POST requests and I noticed that SOMEWHERE (still trying to narrow it down) in the HTTPClient.cpp file around this area: if(!_client->connect(_host.c_str(), _port, _connectTimeout)) { something happens causing my free heap to drop. If this is irrelevant, please disregard.

me-no-dev commented 3 weeks ago

@seansimmons74 it is irrelevant and should be fixed in 3.0.4

Armagedon13 commented 3 weeks ago

Is there any way to know the ESP NOW overflow? I tried sending more than the limit, the protocol stops working until the Esp32 is restarted, the size of the weight scale data never exceeds 70 bytes. I changed the heartbeat to only send one recognition byte, it does this every 5 seconds, maybe this overflows the protocol? I was testing if there are memory overflows but I don't see any errors.

me-no-dev commented 3 weeks ago

It is very hard to say, given that you do not provide any logs :) why not look into our library and try to use that instead.

Armagedon13 commented 3 weeks ago

@me-no-dev well... i see the examples but i don't understand how to use it, to make this i search over internet and see a good tutorial this, i just wanna make a bidirectional communication like i made, but im gonna try to make it.

me-no-dev commented 3 weeks ago

@P-R-O-C-H-Y will help you next week

lucasssvaz commented 3 weeks ago

seansimmons74 commented 2 weeks ago

@seansimmons74 it is irrelevant and should be fixed in 3.0.4

@me-no-dev I'm still pretty new to all this but are you saying Arduino Core v3.0.4? I'm using platform IO and I'm a bit confused on how to upgrade to that. I see that even the latest espressif32 platform version is v6.8.0 and that only supports v2.0.17 of Arduino. Can you point me in the right direction to get this stuff updated to the proper version, please? Also, can you drop a link to the patch that you say fixes the problem in 3.0.4, please? Thank you for your help.

Jason2866 commented 2 weeks ago

@seansimmons74 The community fork pioarduino supports actual core 3.0.4 with Platformio https://github.com/pioarduino/platform-espressif32

seansimmons74 commented 2 weeks ago

@seansimmons74 The community fork pioarduino supports actual core 3.0.4 with Platformio https://github.com/pioarduino/platform-espressif32

@Jason2866 Ok I managed to update and am running 3.0.4. Also verified that the HTTPClient and WiFi libraries updated along with it (Build shows dependencies @ 3.0.4). I am still having the issue I mentioned before. Any other advice would be appreciated. If I need to create a proper issue somewhere, can you let me know where the right place might be?

me-no-dev commented 2 weeks ago

@seansimmons74 please open a new issue with minimal example to reproduce and good explanation on what and how it's happening.
