Answers checklist.

• [X] I have read the Rainmaker documentation and the issue is not addressed there.
• [X] I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• [X] I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

IDF / ESP32-Arduino version.

v5.2.1

Operating System used.

Windows

How did you build your project?

Command line with idf.py

Development Kit.

ESP32-C3-DevKitC-02 v1.1

What is the expected behavior?

During the provisioning stage,

1. WiFi router/AP credentials should not be stored locally at the device level until connection is success.
2. Device should respond if it is unable to connect with WiFi Router with empty password string
3. Device should allow user to reconfigure the WiFi Router credentials details if it is incorrect.

What is the actual behavior?

During the provisioning stage,

1. Device is storing WiFi Router/AP credentials before it's verification
2. Device is keep trying to connect with the WiFi Router/AP with empty password string
3. Once device has reported that it is unable to connect with the WiFi Router/AP with provided credentials, second time during the provisioning it is not providing list of the WiFi Routers/APs available to select from the mobile app.

Steps to reproduce.

Use case - 1

1. During provisioning share empty password string

Use case - 2

1. Provision device with incorrect password
2. Once provisioning is failed, restart provisioning process from the mobile app (ESP RainMaker App)

Not sure if this i still an issue (and apologies for missing this out) but you also need to reset the device to factory settings as prompted by the phone app. Only then can you restart provisioning.
