Answers checklist.
IDF version.
v4.4.2
Operating System used.
Windows
How did you build your project?
Eclipse IDE
If you are using Windows, please specify command line type.
None
Development Kit.
ESP32-Wrover E Rev 3
Power Supply used.
External 3.3V
What is the expected behavior?
I expect aws to re-connect back to AWS when there is a network or internet disconnection and re-connection.
What is the actual behavior?
It is not able to manually reconnect my device to AWS after there is a network disconnection issue.
Steps to reproduce.
Step 1- Connect ESP to AWS once.
Step 2- Disconnect the internet from the WiFi Router.
Step 3 - Reconnect it back after sometime.
Step 4 - Do Step 2 and 3, three to four times.
