So i got this plain ESP-WROOM-32 (Not the NodeMCU like Dev-Board with cp2102 included)
Soldered it, connected it to my (separate) cp2102, now it's up and running.
Using picocom i see:
I did not flash it (yet) so this is all Factory.[...]

I can see the ESP32 in WiFi AP list and connect to it with my tablet, but now i'm stuck.
Can i use this without flashing my own firmware?
Can i send a sketch (arduino IDE foo.bin) via OTA?
I guess i probably got to set my WiFi AP's SSID/PW somehow (With my Tablet?)
I tried to go to http://192.168.4.1 but there is no webserver running...
All tutorials i found begin with compiling and flashing the ESP-IDF firmware
Help!
