boot crash: /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/freertos/queue.c:1442 (xQueueGenericReceive)- assert failed!

[jdpnlapperry1]

I am setting up a new Arduino ESP32 Feather board with BME680 sensor. The sample sketches I tried are working, and I have started to adapt the sample code.

My code compiles fine, but crashes with the following output:

Rebooting...

I installed the Exception Decoder in the Arduino IDE and get the following:

I am not a developer and am trying to hack my way through fixing this. Any help would greatly be appreciated!

You cannot call configTime until WiFi has been initialized.

lbernstone: Thank You! Thank You! Thank You! That was the issue...

[lbernstone]

It is there in the traceback if you know how to read it. Please close the issue.

@lbernstone

This issue happens also when i am using sim7000g. What should I modify to make it working?

I've made the modification you've suggested, but I still receive the same error.

I also added "WiFi.mode(WIFI_MODE_AP);" just before "if (!Esp32MQTTClient_Init((const uint8_t*)connectionString))" and the last thing I see in the monitor is "Info: Initializing SNTP".

PS. I also modified sntp_lwip.c

I added "#include "tcpip_adapter.h" and
int SNTP_Init()
{
LogInfo("Initializing SNTP");
tcpip_adapter_init(); // Should not hurt anything if already inited
sntp_setoperatingmode(SNTP_OPMODE_POLL);

and remains here, just like adding "WiFi.mode(WIFI_MODE_AP);"

Probably SNTP is waiting for the WiFi connection to be ready and I am using the GSM.

Indeed the problem is not the Azure MQTT client. Although the modem is connected to internet and I obtain an IP, the whole connection process is not completed.
