Hello folks,

after stabilizing the wifi (pings are running fine now), I've some problems with MQTT / TLS - MQTT without TLS is doing fine.
Version: esp-idf v.3.3
Client: esp-mqtt
Broker: Mosquitto (Debian Stretch & Debian Buster)

I enabled TLS debugging at first, the mqtt-client is able to send ...

Heiho,

I added an non-scan-period of 1s. It appears to be more stable.

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 ...

Hello folks,

I'm running a small test network of 8 ESP32 devices on desk. ESP-IDF is release/v3.3 (branch), project is https://github.com/fieldtracks/JellingStone . The devices to BLE scannning + beaconing. Results are transfered over wifi / mqtt.

Every couple of minutes some devices loose their ...

... 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 ...

Hello folks,

after upgrading to esp-idf v3.3 and using the built-in mqtt client, I run into errors

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,

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,

Hello folks,

esp-idf supports handling duplicates:

CONFIG_BLE_SCAN_DUPLICATE : This select enables parameters setting of BLE scan duplicate.
CONFIG_DUPLICATE_SCAN_CACHE_SIZE: Maximum number of devices which can be recorded in scan duplicate filter. When the maximum amount of device in the ...

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 ...
