I just had the same problem when trying to use the Async MQTT client. When connecting to the Wifi for the first time manually in boot.py it worked fine, but when the MQTT client was trying to reconnect to a broker that had been gone I got the error wifi: STA_DISCONNECTED, reason:15 (4WAY_HANDSHAKE_T...

Hello, I am running endurance tests on a ESP32-PICO at the moment. From time to time there are wifi connection interrupts and sometimes, not sure if this is during the interrupts, there are messages like I (5558837) wifi:new:<6,0>, old:<6,2>, ap:<255,255>, sta:<6,0>, prof:1 I (5559857) wifi:new:<6,2...

Ok, now that I know what to search for: https://github.com/m5stack/M5Stack/issues/52 https://forum.lvgl.io/t/problems-with-interface-after-connecting-to-network/2130 Meanwhile I also contacted m5stack support via email, directed them to this post and they told me this: "…btn read can`t use irq event...

Ok, I get it now. You could be onto something. With the very simple program that cycles the LED color on button press the trigger is IRQ_FALLING, and that works fine. But there is also no WiFi. That could indeed be the reason. I will dig into this. Above I mentioned that the timing of the callback i...

I tried if there is a difference when I change the trigger, but there is none trigger = Pin.IRQ_FALLING | Pin.IRQ_RISING trigger = Pin.IRQ_RISING trigger = Pin.IRQ_FALLING All show the same behaviour and the automatic triggering of the callback always stops it the button is pressed and hold. I would...

I have more information on this. I tried another ESP32 dev kit, the M5Stack Atom Matrix, instead of the Atom Lite, but the issue stays the same. So the hardware is not broken. The interrupt is defined as pin = machine.Pin(39, machine.Pin.IN, machine.Pin.PULL_UP) trigger_all = Pin.IRQ_FALLING | Pin.I...

Simple program that changes the LED colour on button press -- works totally fine Yes. Simple program that occasionally sends MQTT messages -- works totally fine Yes. First program that now sends an MQTT message instead of setting the LED colour -- causes reboots and repeat messages No, the MQTT mes...

It's GPIO39 of the ESP32-PICO. The pull-up for the switch is just done pin = machine.Pin(39, machine.Pin.IN, machine.Pin.PULL_UP) And at least for the build-in button, I think it's not possible to tinker with it. There is a little schematic at the bottom https://docs.m5stack.com/#/en/core/atom_lite ...

Hello all, I have a strange problem and hope that you have some ideas. Hardware is a ESP32-PICO D4 in a M5Stack Atom Lite. My first program to test interrupts in general works like a charm, it changes the color of the LED when the button is pressed. There are not bounces, color skips or what ever. T...

Thanks for your answer, that was new to me.
