ProhibitedCause

[dennisbach]

Hi Copercini,
Thank for your project. However, I programed in my board, it run failed.
Fatal exception 29. Fatal exception 28.
It means field of memory, it's protected and cannot load or store data into there.
Do you have any solution for this?
I tried to find the way store cert and key to another field of memory, but I don't know where is suitable.

Thanks

Hi @dennisbach ,
I finally get it work. Now it can connect to AWS IoT via MQTT successfully. I only met these Exception 29 or 28 when the connecting process failed. It means that the CA, Cert, Key may be incorrect. Please give us more information to help you solved the problem.

Hi @JimmyTai
First, about CA, Cert, Key, I already tested with MQTT.fx apps on PC. It ran successfully.
However, when I run on ESP8266, it printout as follow:

Hi @dennisbach ,

I am sorry for late reply.
I already put my whole esp8266 Arduino core on my Github.
Also I create a library to help you loading the certification and private key.
This is the link: https://github.com/JimmyTai/esp8266-AWSIoT

Hi @JimmyTai
Thank you so much. I will try and share my result later.

Hi Xuan, I am glad to hear that. Please let me know if there is any problem. By the way, hope you can give my github repo a star and share with other people who need it. Thank you. Jimmy
