I need to add to standard firmware:
- Ethernet commands
- WebSocket commands
- FS commands with 512kB partition for user space
- BLE commands
Also need OTA service.

ESP32-WROOM32UEN4 have to small Flash memory. Can I use bigger one (8M/16M)?
Have to adjust partition table only or other things also? Or can't use it?

@DexterM Of course. If FS partition only requires 512 KB, you can use an ESP32-WROOM module with 8 MB of flash. You'll need to adjust the partition table files partitions_at.csv and at_customize.csv, as well as some partition-related configurations in sdkconfig.defaults. If you run into any difficulties, I can help you resolve them.
