Problem with connect to AWS mqtt usind Ethernet board enc28j60

[marcoavaccaro]

Hello guys,

I'm using an esp32 dev board and an enc28j60 module to send messages to aws iot plataform using mqtt. I already done that using wifi but now i'm trying use ethernet.

I also already could post a tweet using this ethernet module with the lib Ethercard.h. So i can connect to internet via ethernet and can connect to aws mqtt using wifi. Now the problem is to do them both.

I could upload the new code to the esp but it crashes entering the function hornbill.connect() just after printing "test"

The log shows until the reboot is:

My IP: 192:168:1:10
Netmask: 255:255:255:0

Rebooting...

So i guess it connect to the internet but some error is happening and i don't know why. The backtrace translaction is: https://i.imgur.com/5BOvjsr.png

I am seeing the exact same thing with my setup when connecting to AWS using a modem (in my case) and not an Ethernet board.

I can connect to AWS just fine over WiFi but as soon as I try with a modem I get the same error you're seeing @marcoavaccaro.

Has anyone else come across this issue when trying to connect to AWS on another connection other than WiFi? Thank you so much in advance!

Hello @marcoavaccaro , did you find a solution on how to connect ESP32 to AWS using Ethernet?

Thanks, Simone

Also facing the same problem with DOIT DEV KIT V1

[woodlist]

I got the same problem on TTGO T1, upon successful establishing GPRS connection and mapping on DDNS, unable to run AsyncWebServer on 80 port. The WiFi is not initialized and do not required in given project

[madaerodog]

Hello guys, I had the same problem with ESP32 and a GPRS connection over Sim868. The way I made it work and my understanding of the situation is as follows:

Although you might not want to use Wifi in your project for the time being you might want to initiate it with WiFi.begin(); because Esp32's internal clock, TCP, other components, and features are only initiated when wifi is initiated.

Even more so, because you are not connecting to a Wifi network that would have given you the current time you have to manually set this internal time, for this, I have used https://github.com/fbiego/ESP32Time and I have used the time provided by the GPRS module upon boot.

My use case involved accessing an HTTPS link with a firmware file to download and install remotely via GPRS with a provided certificate. So without the internal components started and the current time correct the request will surely fail.

So as a quick summary of the fix:

include

include

ESP32Time rtc(3600); // offset in seconds GMT+1

and in setup before doing anything else:

WiFi.begin(); rtc.setTime(30, 58, 15, 13, 7, 2022); // you either set time manually or take it from your Ethernet / GPRS module

And this was the only way to make it work and not get the error. Hope it helps!

[mirkogeest]

This saved my day, thank you @madaerodog!

I only have added the WiFi.begin() without the setTime and now the aws iot sdk works like a charm.

My hardware is a LilyGo T-SIM7080G-S3 ESP32-S3 (TINY_GSM_MODEM_SIM7080), and the exact error I got when calling hornbill.connect was: assert failed: tcpip_send_msg_wait_sem IDF/components/lwip/lwip/src/api/tcpip.c:455 (Invalid mbox)
