[kklokeshkumar]

I Powered on the ESP32 DevkitC with ESPwroom32D module.
Opened Serial terminal @115200 buad rate. and Found the below mentioned Messages.
My Questions are:
1.what is the default Firmware Loaded in the ESP32 Module?
2. Does Default Firmware module Have AT command interface?.
3. What is SSC commands?. & Why SSC commands is used by default inspite of having AT commands?.
4. Can any body explain What does these messages mean to the Beginner?.

I think this message will help so many people who are looking for this basic information like me.

1. Ssc = simple serial commands
2. No
3. https://esp32.com/viewtopic.php?t=484, factory test
4. Just bootloader diagnostic messages

You should just load another firmware like AT, micropython, nodemcu, ...

Thanks for the Reply.
1. Apart from SSC What all is implemented in the Default Firmware?. Can you provide me any document related to that?.
2. So we have to write a new project after we buy the module right?.
