As of now I think these things are missing:

• Bluetooth Classic (and pairing and all that)
• Light Sleep for WiFi
• SPI Slave mode
• IPv6
• ESP-NOW
• Access to low level assembler

Hi! Without doing a lot of research I have ordered a few ESP32 modules and was surprised to find that classic Bluetooth wasn't available yet. Are there any other capabilities, that are still in the making?

Wanted to provide a bare minimum of security for a quick public demonstration and decided to add a push button to a GPIO pin, that has to be pressed while connecting. Wouldn't secure my credit card info like that, but for what I needed it works fine!
