Re: wifi / mqtt instability

Heiho, BLE and wifi are using the same radio. You need to change ble scan window and interval to give more radio time to wifi or stop scanning when publish mqtt data. Thanks for your help! That sound's reasonable. Do you have some concerete values / parameters in mind? What window / interval can you...

Re: Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.

... well, it turned out, that I made a typo a few months ago. Screwing up git submodule add, I got two mqtt-clients in my system. While the was using the correct one, the linker was not. Over the time, the progress made the new mqtt-client less and less ABI compatible to the one in my esp-idf direct...

Re: Guru meditation error (core 0 panic loadprohibited) when building with log level -> no output

Heilo,

I'd seems like I'm running into the same issue using a different firmware. Unfortunately, I don't understand your hint for increasing the task size. :-(

What are refereing to exactly. Is there a build configuration option?

Thanks,

Lipo voltage Lolin D32

Hello folks,

I'm wondering how to measure the LiPo voltage using a Lolin's D32. I wasn't able find any pins attached to one of the adcs. Do you know a code example for putting the esp32 into deepsleep when the battery reaches a critical level?

Thanks,

Memory model: How to synchronize acces?

Hello folks, I'm somewhat puzzled about freerots' memory model - I wasn't able to finde a suitable reference, yet. To illustrate my confusion, I modified the example blink app, to read data from the heap: #include <stdio.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "driver/g...
