What is the cheapest solution to add WLAN/BT to a STM32F4/F7 MCU?

[Davorin]

Good afternoon

Looking for a simple solution to add WiFi and/or BT connectivity to a STM32F4/F7 MCU..

USB dongles are out of question as it would require to a Linux system...

Seen that some people are using ESP32 hooked up to UART...but I am not sure if those chips have IPv6 support in their firmware...

thanks in advance

Not sure about cheapest, but from development cost POV it is very simple.

Ah great...there's even a cheap dev kit for it....

Something similar for WLAN as well?

ESP8266 are very popular and I'm sure someone has implemented IP6 on them. There is a lot of firmware running around so sometimes it's difficult to know exactly what you need.
