Hi there,
I've got a ESP32-C3 AWS Devkit last week and, after upate its firmware revision (I received the unit with a old 0,x,x revision so I updated to Rev. c1.0.20.bin using OTW as described at point 9.2 of "Getting Started Guide for Espressif's AWS IoT ExpressLink Evaluation Kit"), I started to send AT commands to its UART port.
It worked properly setting SSID and Password of my WiFi network, I readout ThingName and its certificate, I created the object with that name in IoT Core of my AWS account but, when I send AT+CONNECT command I get the "ERR14 4 UNABLE TO CONNECT Failed to securely authenticate with AWS" error message: I received this message after only 2 or 3 seconds after sending the AT+CONNECT command.
I also tried the "Start_Quick_Connect" software using the USB port of the DevKit but and I got an other error message: "Something went wrong while processing the request. Response: ["message":"Thing doesn't exist"}, Status code: 400.
I let you know that I have already set objects in AWS IoT Core, so I don't think that there is something wrong there.
However I followed the instructions at point 6.c of the previous document.
Any ideas?
Thank you all.
